A Scottish surgeon in colonial India …

The eldest son of a Church of Scotland minister, James Esdaile was born in Montrose in 1808. He studied medicine at the University of Edinburgh, obtaining an MD in 1829 with a dissertation on narcotics.Footnote ¹⁵ As he suffered from chronic bronchitis and asthma, he was advised to live in a tropical climate. Through his various contacts he was successful in securing a junior, but nonetheless lucrative, position in the medical services of the British East India Company as assistant surgeon in 1831. Apart from the fact that he served in Azamgarh in central north India, little is known of those early years, which seem to have passed uneventfully. However, continued ill health forced him to take long leave for three years, from 1836 to the end of 1838. During this period, he travelled back to Britain, using the sea-cum-land route via Egypt and continental Europe.Footnote ¹⁶

Soon after his return to India, Esdaile was posted as civil surgeon at Hooghly in early 1839.Footnote ¹⁷ In addition to his duties, which included running the hospital attached to the town's jail, he also oversaw the functioning of the Imambarah Hospital and College – created by prominent Bengali Shi'a Muslim philanthropist Muhammad Mohsin (1732–1812), and managed by the East India Company – which was at the time under the charge of Dr Badan Chander Chaudhari, a graduate of the Calcutta Medical College.Footnote ¹⁸ Esdaile's first years at Hooghly seem to have been as uneventful as his earlier stint in upper India, his activities having left few traces other than three letters written in 1844 from Hooghly to his senior colleague and friend, Dr John Grant (1794–1862), superintending surgeon of Bengal, then on leave in Britain. The letters show him to be a well-read man with a wry sense of humour, at ease in French and Latin. We learn he had his eyes set on a more important medical appointment in Calcutta – a professorship at the Calcutta Medical College, for example – anything to get him away from what he called ‘the wretched and obscure village’ of Hooghly.Footnote ¹⁹ We know from his earlier writings, especially from his travelogue, that he found the summer heat unbearable and life in provincial India torpid and monotonous amid largely self-indulgent and irresponsible colleagues. And while he reckoned that Indians ‘have great quickness of apprehension, wonderful application, retentive memories … are very curious, and [can] make rapid progress in our language, and knowledge’, they were ‘exclude[ed] from places of trust, and emolument’, by the heavy exactions of irresponsible government ‘and by the grinding of the poor by the rich’. Also, he found the Indian lower classes ‘hideous’, but attributed this to ‘hard work, exposure and bad food’. Nevertheless, he staunchly believed in the long-term civilizing benefits of the British colonial enterprise as long as it was based on ‘general education, and the introduction of our arts and sciences’.Footnote ²⁰

Nothing out of the ordinary can be gleaned from Esdaile's professional activity in these early years. We learn from an article he published in 1845 in the Indian Medical Journal – reprinted soon after in the Boston Medical and Surgical Journal – that he had treated two cases of European patients suffering from non-secretion of bile using innovative, yet conventional, remedies.Footnote ²¹ In another reprint in the same issue of the Boston journal, he relates a remarkable case of aneurism by anastomosis where he was led as a last resort to operate on a prisoner for a tumour on his head in order to save his life. If the operation itself was particularly daring, long and complicated, the procedure and post-operative medical care were yet again conventional.Footnote ²² And although he makes no mention of pain in either report, we learn from some of his other writings that he had to perform many operations in which the patients suffered from intense pain and, often, fatal post-operative trauma, eventually leading to a very high mortality rate – around 50 per cent – common for operations of this importance.Footnote ²³ Esdaile describes one such case soon after his arrival in Hooghly: ‘a peasant was brought to the hospital with a prolapsus ani, the size of a pint bottle, that had been down for several days. Cold and astringent lotions were applied to the part for many hours, and he was suspended by the heels as long as he could bear it, before an attempt was made to return the protruded part. The most persevering efforts at reduction were continued for two days in vain, and the man was carried home by his friends to die miserably’.Footnote ²⁴

… Turns magnetic …

It was the search for a means ‘of alleviating … suffering among the natives of Bengal’ that brought Esdaile's attention to mesmerism through the writings of Dr John Elliotson (1791–1868), professor of the principles and practice of medicine at University College London and senior physician at the University College Hospital.Footnote ²⁵ A brilliant physician and teacher whose life was hallmarked by unorthodox tendencies, Elliotson had a vast public following, including among contemporary literati – Wilkie Collins, Charles Dickens, George Eliot, Harriet Martineau and Edgar Allan Poe, to name some. A champion of phrenology – having founded the London Phrenological Society in 1823 – he was also one of the earliest to introduce the stethoscope in Britain. Elliotson's tryst with mesmerism dated from the autumn of 1837 when, on closely observing the demonstrations in London of the Frenchman Jules Denis Dupotet (1796–1881), he began using it to relieve his patients of pain in surgery.Footnote ²⁶ However, his penchant for public spectacle which attracted huge audiences, including celebrities and royalty, led to a series of serious controversies with his colleagues. A lasting antagonism towards mesmerism from the Lancet's founder–editor, Thomas Wakley (1795–1862), exacerbated the hostility of a naturally conservative medical establishment, and culminated in an eventual ban on practising mesmerism in the hospital's wards. Undaunted, Elliotson continued using it in his private practice and spent his personal fortune to launch and edit The Zoist, a widely read quarterly periodical, published between 1843 and 1855 and devoted to phrenology and mesmerism. It carried contributions from Herbert Spencer and Sir Richard Burton, among others.

In his wide readings around mesmerism and its history going back to the French Commission of 1784, Esdaile was particularly struck by a recent request from the Archbishop of Lausanne and Geneva to the Pope asking whether Rome would permit the generalized use of animal magnetism in his diocese. He remarked that while Rome summarily rejected the request, the judgment did not contest the facts – that is, the reality of mesmeric or magnetic phenomena – rather it was based purely on the dread that it was ‘probably of diabolic origin’.Footnote ²⁷

Esdaile began to understand mesmerism as not ‘a new and unnatural art’, concluding,

While eschewing all theoretical speculation about what he called the ‘metaphysics of mesmerism’, he reckoned that the body's ‘vital powers’ ‘of one person can be poured into the system of another’, contrary to the widespread belief amongst most European medics of their being confined within the body's limits.Footnote ²⁹ The medic's role, ‘instead of doubting or dogmatising about Mesmerism’, was, then, to put his convictions to the test – ‘for it is a thing to be done, and not talked of only’. The subject needed to be taken up experimentally, ‘without previous knowledge of it, and having no theories to make or defend, that the truth or falsehood of Mesmerism may be speedily decided’.Footnote ³⁰

Conscious of the hostility of his own medical hierarchy in Britain, and even amongst his colleagues in India, Esdaile resolved to find out the truth for himself on the first favourable opportunity – which, in order to avoid any suspicion of contrivance and complicity between him and the patient, entailed finding a patient who would fulfil at least the following five conditions:

The opportunity presented itself on 4 April 1845. Madhab Kaura, a low-caste, illiterate and ‘ignorant’ felon condemned to seven years’ rigorous imprisonment in the Hooghly jail afflicted with double scrotal hydrocele, was brought to the Imambarah Hospital, where Esdaile immediately drained some of the liquid and disinfected the incision with corrosive sublimate (bichloride of mercury). Seeing the man nonetheless continue to suffer from acute pain, he decided to operate upon him under mesmerism with the help of Dr Chaudhari, who was in charge of the hospital (Figure 1). He reckoned that Kaura – ‘the very worst specimen of humanity, theoretically considered’ – provided an ideal subject for his experiment as he could never have heard of mesmerism, thus eliminating all risk of collusion between operator and subject. In addition, he fulfilled the other four conditions mentioned above.Footnote ³² However, never himself having witnessed mesmerism at first hand, learning that Dr Chaudhuri had only seen it practised once ‘but without effect’ while a student at the Calcutta Medical College, and unable to reach the Bengali magician he was only to meet a couple of months later, he devised his own technique:

Just then the man began to show signs of falling into a trance.

Esdaile lost no time in contacting the district judge and a senior tax official, who, along with his indigenous medical staff, were invited to witness the experiment, which he carried out in stages over the next eight days, each time in the presence of eyewitnesses, both European and Indian, who were to furnish written testimonies. The water having been completely and painlessly removed from the scrotum, Kaura was relieved and recovered effortlessly in a matter of days.Footnote ³⁴

With tens of affidavits from reliable eyewitnesses under his arm, along with attested illustrations of the patients (such as those reproduced here), closely followed by the meeting with the local magician, Esdaile could now triumphantly declare that his experiment was a total success. In the months that followed, Esdaile successfully performed a total of seventy-three major surgical operations, including fourteen for massive scrotal tumours weighing between four and fifty kilos (Figure 2).

Figure 2.

Hurronundo Saha, a twenty-seven-year-old patient with a scrotal tumour as large and, at fifty-three kilograms, almost as heavy, as his whole body, operated on on 14 October 1846 in the presence of Dr Duncan Stewart, Presidency surgeon and professor of midwifery at the Calcutta Medical College, whose eyewitness account of the operation appears in James Esdaile, Introduction of Mesmerism into the Public Hospitals of India, 2nd edn, London: W. Kent and Co., 1856, pp. 22–3. From ibid., Appendix.

Indeed, ‘these singular and prodigious tumours are so common in Bengal’, observed Esdaile, ‘that they may be considered as an endemic curse of the climate, the disease [being largely] confined to the sea-board of India’.Footnote ³⁵ His technique was all the more striking when compared with what he referred to as the ‘worse than useless’ native treatment, which

As news of his painless method spread, Esdaile's other mesmeric operations in these first months included drainage of hydrocele, excision of tumours, amputation of limbs, mastectomies, penectomies and the occasional extraction of teeth. He also sometimes used mesmerism in medicine to treat pathologies such as headaches, tic douloureux, colic, rheumatism and eye inflammation.Footnote ³⁷

Importantly, however, Esdaile performed few mesmeric manipulations himself as he was rarely successful in going beyond attaining a state of somnolence in his patients. He attributed this to the disproportional effort he had to put in given his weak health and chronic pulmonary problems.Footnote ³⁸ Saving his own strength for the performance of surgery, he employed a battery of about a dozen indigenous Hindu and Muslim mesmerizers aged between fourteen and thirty years, most of them compounders and dressers from the Hooghly Hospital:

He also taught and employed some of his recovered patients as mesmerizers.Footnote ⁴⁰

A separate operator was assigned to each patient. They worked in silence in darkened rooms on individual patients who, like their mesmerizers, were bare-bodied, wearing only a loincloth to cover the midriff. The operator sat behind them, leaning over and nearly in contact with their face, and made passes from the back of the head to the pit of the stomach, dwelling mainly over the eyes, nose and mouth. Although Esdaile was aware of individual variations, these were not really of concern to him.Footnote ⁴¹ Indeed, as mentioned earlier, he firmly believed that beneath this plurality of techniques lay a common phenomenon known to Europeans as mesmerism. He held that while there was a considerable degree of homogeneity in the techniques that he shared with his collaborators, these contrasted to what he referred to as the ‘European method’, a distinction he dwelt on in some detail in his writings.Footnote ⁴² What mattered to him was that the same effects be produced ‘on the banks of the Thames, and the Seine, the Rhine, and the Hooghly’. Climatic differences were irrelevant: ‘It is not supposed that the truth is affected by degrees of latitude’, as he summarily put it.Footnote ⁴³ For Esdaile, local practices, those in Europe included, were then to be conceived of as distinct and yet mutually translatable.Footnote ⁴⁴ Furthermore, as he believed that mesmeric phenomena were produced through the movement of certain ‘vital powers’ between operator and patient, the nature of the actual rituals used or spells chanted mattered little – hence his own provocative chanting of the ‘King of the Cannibal Islands’ during his encounter with the magician referred to in the introduction above.

All the while, he painstakingly accumulated affidavits from eyewitnesses whom he had invited from a wide section of society in and around Hooghly, as well as from Calcutta, to attend almost all his mesmeric operations. These took place in a specially constructed operating theatre with separate spaces for trance induction and for surgery, both open to view by the invited witnesses. They included his European and Indian medical colleagues and subordinates in Hooghly, colonial civil servants, the principal of the Hooghly College and various teachers, but also physicians and surgeons from Calcutta, professors from the Calcutta Medical College, the French governor of Chandernagore, the archdeacon of Calcutta and a number of clergymen, as well as members of the Bengali elite, the bhadralok. As he put it,

On 29 July 1845, a public exhibition was arranged at the district and jail hospitals at Hooghly, the account of which was published in the form of a letter in The Englishman, a Calcutta newspaper: ‘The party was very numerous, two steamers having brought the curious from Barrackpore [a British military cantonment] and Calcutta’, it read, ‘and there was a large assemblage of the European and Native residents of Hoogly and Chinsurah [the one-time Dutch township nearby]’.Footnote ⁴⁶ In a separate account, Esdaile himself mentioned that ‘six medical men were of the party, and one of them publicly acknowledged the faithfulness of the report sent to the newspapers’.Footnote ⁴⁷

Esdaile reported his early results in the India Journal of Medical and Physical Science. He simultaneously published them in a small booklet for the general public entitled Mesmeric Facts, warning his readers, however, that they would not find in it ‘the most efficacious processes for exciting the mesmeric action in the system, because I should be sorry to be instrumental in making mesmerism easy to the unprofessional Public’.Footnote ⁴⁸ He also immediately started a correspondence with the figureheads of mesmerism in Britain, notably Elliotson, who lost no time in reprinting Esdaile's correspondence and reports in The Zoist, and he published in the Calcutta Medical Journal, the India Register of Medical Science and the major local newspapers, notably the Englishman and Military Chronicle and the Bengal Hurkaru. Many of them, including the newspaper articles, were also almost immediately reprinted in medical journals such as the Boston Medical and Surgical Journal and the (Boston) Medical Times. And newspapers in Bombay, Madras and Delhi, as well in Britain, Australia and the United States, were quick to report on Esdaile's achievements. However, many of his colleagues, especially members of the influential Medical Board in Calcutta, showed hostility to mesmerism.

In February 1846 Esdaile received orders to join the Company's armed campaign against the Sikh kingdom of Punjab. Before leaving, he addressed a detailed report of all his operations to the Medical Board, which it ‘did not condescend even to notice’. Footnote ⁴⁹ He also hurriedly mailed a manuscript containing a detailed account of his mesmeric experiences as a working surgeon and the path that led him to them to his father in Scotland. The latter, with the help of his younger son and fellow clergyman, David Esdaile (1811–80), succeeded in getting the book published in London under the title Mesmerism in India, and Its Practical Application in Surgery and Medicine the very same year. Based on factual and certified evidence and seeking to distance itself from the plethora of cynical manipulators and false priests of mesmerism, the book was an appeal to metropolitan colleagues and the lay public to pressure the conservative medical establishment in favour of mesmeric anaesthesia. ‘From the moment I witnessed the extreme degrees of Mesmerism,’ Esdaile declared in the text,

The book was an instant success, with a US edition appearing within a year, in 1847, with a reprint in 1850.

… And mesmerizes Calcutta

On his return from military service later that year, Esdaile addressed a detailed report of the seventy-three cases with eyewitness reports directly to the government, bypassing the Medical Board. The deputy governor of Bengal, Sir Herbert Maddock, reacted promptly, ordering further experiments to be conducted. For this purpose, a room with accommodation for ten patients was allotted in the Calcutta Native Hospital for the admission of patients willing to submit to operation under mesmerism, and a committee appointed by government to watch and to report upon the experiments carried out by Esdaile. The committee consisted of three doctors, three European lay members and four members of the indigenous elite. Despite some scepticism on the part of certain members – notably its secretary, William Brooke O'Shaughnessy (1809–89), already well known for his pioneering work on galvanism and telegraphy, who was at the time professor of chemistry and materia medica in the Calcutta Medical College and lobbyist for cannabis – their report was on the whole positive, and in November 1846 the governor general of India, Lord Hardinge, sanctioned a small hospital in Calcutta to be put at his disposal.Footnote ⁵¹ By 1848, a mesmeric hospital supported entirely by public subscription was opened in Mott's Lane in central Calcutta especially for Esdaile's work. This provided him the opportunity to expand his clientele, which now included well-off Indians and also a small number of Europeans.Footnote ⁵² However, it was closed eighteen months later, ether and chloroform having won the day over ‘magnetism’. Chemical anaesthetic agents, it was argued, were incomparably cheaper than the wages of dozens of human mesmeric operators and much quicker to act than the many hours, and sometimes days, it took for the latter to effectively put their patients to sleep. The economic argument, in addition to pressure from a hostile medical establishment back in Britain, seems to have won the day: the East India Company authorities were always on the lookout to limit expenditure.

However, thanks to the local press and protests from a large and influential section of ‘the native community’ expressing their faith in ‘a science, the value of which, if not as yet fully known, they have learnt to appreciate from the evidence of their own senses’, the Mesmeric Hospital reopened in the Sukeas’ Lane Dispensary in September 1849.Footnote ⁵³ Although far removed from the city centre of Calcutta and thus less visible, it still attracted patients – and attention. It was even visited by foreign dignitaries, for instance by Jan Jacob Rochussen (1797–1871), the Dutch governor general of Java, who even resolved to set up a similar hospital on his return to Batavia.Footnote ⁵⁴ And Dupotet reported on the mesmeric activities in Calcutta in his Parisian Journal du magnétisme.Footnote ⁵⁵ At the same time, news of Esdaile's success spread within British India, leading medics elsewhere in the subcontinent to emulate his method, the reticence of the colonial medical establishment notwithstanding.Footnote ⁵⁶ One Dr Charles Davidson, a Company surgeon, communicated with Esdaile on his observations of indigenous trance-inducing techniques known in north India as jhar-phoonk, and later communicated with Elliotson on such practices all over the subcontinent.Footnote ⁵⁷

In 1848, the new governor general of Bengal and fellow Scotsman, Lord Dalhousie (1812–60), demonstrated his esteem for Esdaile and his work by appointing him to the position of Presidency surgeon and, whilst not supporting the continuation of the mesmeric hospital in Calcutta, in the following year gave Esdaile the position of marine surgeon, the highest and most lucrative post in the civilian medical service in Bengal. Having completed his full tenure of twenty years’ service with the East India Company, conducting 260 operations under the influence of mesmerism during his last six years in India, with a death rate down from 50 per cent to 5 per cent, Esdaile returned to Britain in 1851.Footnote ⁵⁸ Although he retired from the EIC's service in 1853, he actively continued to work and write for the cause of mesmerism. And he could count on the unfailing support of Lord Dalhousie, who even wrote a testimonial certifying the veracity of Esdaile's account of his mesmeric work in India.Footnote ⁵⁹

As for the continuation of his work in India, ‘After the departure of Dr. Esdaile to England mesmerism received no encouragement owing to a majority of medical men giving preference to chloroform in operative surgery’, wrote Dr Badan Chunder Chaudhuri, the medical officer in charge of the Imambarah Hospital and Esdaile's collaborator in his early experiments.Footnote ⁶⁰ However, even though the use of mesmerism disappeared from the repertoire of colonial surgeons with Esdaile's retirement, we might still ask whether his numerous indigenous assistants did not continue to practise it. We do know that the three original mesmerizers at the Imambarah Hospital in Hooghly remained on the staff until 1863. A report by Dr James Elliot, then the civil surgeon at Hooghly, dated 19 June of that year, further noted that two of them, who were well qualified, had recently obtained employment as native doctors, while the third was carrying on as compounder at the city's jail.Footnote ⁶¹

By the time of Esdaile's return, several hospitals dedicated to mesmerism had mushroomed across the British Isles, including in Bristol, Dublin and Exeter.Footnote ⁶² Esdaile himself was active in setting up the Scottish Curative Mesmeric Society and in the administration of Elliotson's London Mesmeric Infirmary. He continued to write and campaign for the globalization of mesmerism as an effective anaesthetic – in The Zoist, but also in pamphlets addressed both to his medical colleagues and to the general public. In one work he pleaded that, even if

He also corresponded with one of the pioneers of mesmeric surgery in Britain, James Braid (1795–1860), distinguishing his own techniques and fundamental conceptions from the latter's hypnotic technique of ‘neurypnology’.Footnote ⁶⁴ Braid had developed this procedure after being introduced to magnetism through the Frenchman Charles Lafontaine's (1803–1892) demonstrations during his English tour in 1841.

Despite his unshaken belief in mesmeric anaesthesia, Esdaile was careful not to be identified as a militant for the mesmeric cause à la Elliotson. ‘I beg the reader not to do me the injustice to think me a Mesmeric doctor’, he pleaded in his book,

He was also open to comparing chemical anaesthetic agents with mesmerism. While he conceded that chloroform could be as successful with moderate-sized tumours, amputations, and so on, it would, he claimed, be fatal in the removal of larger tumours:

Esdaile died in London in early 1859. Although his ‘magnetic crusade’ was soon forgotten and his experiments were swept into oblivion in European and colonial medical establishments in the latter half of the nineteenth century, his experience has been kept alive in other quarters, notably amongst practitioner–historians of medicine in the United States, and parapsychologists in Britain.Footnote ⁶⁷ As for the occult healing practices which Esdaile came into contact with and incorporated in his own surgical procedures, they continued to enjoy a vigorous life in Bengal and even experienced a renewal towards the turn of the twentieth century, incorporating hypnotism and mesmerism into ‘traditional’ tantrism.Footnote ⁶⁸

Hospitalizing magic, globalizing mesmerism

It is clear, then, that Esdaile's mesmeric enterprise cannot possibly be understood within the diffusionist model, which has all too often been mobilized to explain the global spread of knowledge, techniques and practices that are deemed to originate in Europe.Footnote ⁶⁹ Nor can it be understood as a case of knowledge transfer, by reducing James Esdaile to a simple passeur (no pun intended), a cog in the wheel of a – one-sided – intercultural transmission.Footnote ⁷⁰ Indeed, Esdaile's enterprise bears little relation to the animal-magnetic movements that had stirred continental Europe since the last decades of the eighteenth century, which were more concerned with the operator controlling the subject's will and senses than with its use as an anaesthetic. Nor does it bear much resemblance to the export and practice of mesmerism in the French colony of Saint Domingue half a century earlier and its eventual appropriation by the island's enslaved population, for whom syncretic forms of Vodou and mesmerism ‘offered freedom from established medicine and … from the authority of the white master’.Footnote ⁷¹ Quite to the contrary, as we have already seen, the flow in Esdaile's case is in the opposite direction, with a Scotsman in colonial Bengal arranging for a meeting between mesmerism and indigenous magic, seeking thereby to establish an equivalence between the two for use in surgery. Yet there is also evidence that traditional magical practitioners in India did begin to help themselves opportunistically to European mesmerism later in the century to create a market for ‘modern’ occult therapies.Footnote ⁷² Furthermore, there seems to have been little or no evidence of aversion on the part of the colonial medical establishment in India to establishing similarities for fear of threatening colonial and scientific authority.

In recent decades, there has been a renewed interest in Esdaile amongst some social and cultural historians of science and medicine. For instance, Waltraud Ernst, while giving a balanced account of Esdaile's mesmeric experience, is, however, primarily interested in the reasons for its eventual failure – principally, she belives, because of his unshakeable belief in the existence of a mesmeric fluid which obeyed the laws of Newtonian physics and his reliance on native Indian testimonies and experiences which she claims lacked credibility in the eyes of the British medical establishment.Footnote ⁷³

However, much of this recent interest comes from scholars of postcolonial and subaltern studies who have been quick to denounce Esdaile as a paragon of colonial attitudes to Indians and their ‘colonized’ bodies. These critiques are largely based on a series of sharp dichotomies: first between scientifically rigorous metropolitan medicine and lax colonial medicine, where the rigorous norms of the metropole are slackened, and where ‘scientific’ research can be practised that is unthinkable, or not ethically permissible, in the metropole, and second between colonial science and indigenous or traditional science or healing practices, which are based on religion, superstition and/or magic.Footnote ⁷⁴

Thus, for Chandak Sengoopta, ‘human experimentation of dubious kinds [was] not shaped solely by an abstract drive for total classification but also by cultural convictions about the bodies and minds of the colonized … in the brief second life that “mesmeric surgery”, out of favour in the metropole, experienced in colonial Bengal’.Footnote ⁷⁵ This paper has shown that mesmerism not only was practised on colonial subjects and European elites in India, but also had a considerable following in medical circles in Britain, France and the United States – and, I might add, Russia. Sengoopta goes on to assert that Esdaile considered Bengalis to be an ‘ignorant, passive, and mindless’ race.Footnote ⁷⁶ The story is far more complex, for while he did believe that his poor Bengali patients were ‘simple, unsophisticated children of nature’, others, such as his assistants, members of the colonial administration and the Bengali bhadralok whom he solicited as witnesses and allies, were deemed to be much more sophisticated.Footnote ⁷⁷ Furthermore, even his ‘simple’ patients could metamorphose into difficult and complex beings, as in the case of a peasant woman named Lokee who came back for a second operation in October 1845 after an initial tumour in her leg was removed under mesmeric influence some months previously (Figure 3).

Figure 3.

This time she could not be influenced as she showed ‘excitement of mind’.Footnote ⁷⁸ Furthermore, the evaluation committee set up by Sir Herbert Maddock (see above) found that out of the ten cases they had witnessed, three did not respond to the mesmeric procedures for want of the required predisposition and had to be discharged.Footnote ⁷⁹

For another postcolonial critic, Gyan Prakash, ‘it was in the public display of its magical effect that mesmerism emerged as a science, perched precariously in between cold scientific scrutiny and superstition in its “widest” and “most absurd forms”’ – science ‘gone native’, as he qualifies Esdaile's practices.Footnote ⁸⁰ Prakash unfortunately ignores a vast body of science studies literature that has convincingly shown that science is essentially native – everywhere – as remarked on in the introduction above.

The best-known of recent critical accounts is perhaps Alison Winter's chapter in her book on Victorian mesmerism, which opens with extracts from the same passage from Esdaile describing his encounter with an Indian magician that I have used here. Interpreting the meeting within the diffusionist framework of the export of ‘Victorian mesmerism’ to India, Winter sees it as a ‘familiar exchange, in which British colonials projected “native superstition” onto Indian culture. Victorian stories of the East’, she continues, ‘scripted dramas whose Indian players performed the superstition and subordination assigned to them, confirming the power and rationality of their British masters’.Footnote ⁸¹

Before engaging with the essential arguments of these critics, let me stress that contrary to the trope shared by all three, the distinction between European and ‘traditional’ Indian medicine was in fact quite blurry and there was a significant porosity between them. British medics relied on a large corps of indigenous assistants who, although often trained at the British-run Calcutta Medical College, were taught from textbooks written by indigenous practitioners which combined principles of European and indigenous medicine almost until the end of the nineteenth century.Footnote ⁸²

Coming now to the central claims of these critiques, both Prakash and Winter view Esdaile's project as a public performance, for the former to ‘transform the Indian viewer from superstitious to wondrous’, and for Winter to ‘convert exotic practitioners into educated medical helpers or discredited superstitious fools’.Footnote ⁸³ Now, even if their use of performance is metaphorical, in what follows I shall take the performance trope literally. First, because the history of mesmerism is inextricably linked with public performances. Esdaile's story is no exception, albeit his performances served very specific purposes and were very differently configured from those in Europe, for instance. Indeed, he was chary of giving public performances outside the surgical context. For instance, he declined an invitation from students at Hindu College in Calcutta to mesmerize one of them ‘because I have made it a rule not to mesmerise, except for philosophical and medical purposes’.Footnote ⁸⁴ Their location, the arrangement of these spaces for public demonstration and the respective roles of, and interplay between, Esdaile and his mesmerizers on the one hand and the audiences on the other combined to define the efficacy of the mesmeric procedures themselves. However, given its importance, the treatment that this subject rightly deserves is outside the limited scope of the present paper, although one of the roles of Esdaile's audience is discussed below at some length.

Second, while it is true that many of Esdaile's operations were public performances, their aims were quite different from those imputed by Prakash and Winter. From all the evidence available, it is clear that Esdaile did not seek to charm his audience into believing in Victorian science and Western rationality, but conversely to ensure that his own procedures found a legitimate place in the pantheon of Victorian science. To this end, he explicitly and repeatedly expressed the need to publicly demonstrate the efficacity of his anaesthetic techniques. In so doing, he was following well-established strategies developed and honed by men of science since at least the seventeenth century – as ‘a way of publicly warranting that the knowledge produced … was reliable and authentic’.Footnote ⁸⁵ By the nineteenth century, public performances were very much part of the process of scientific experimentation, Michael Faraday (1791–1867) being one of its best-known proponents.Footnote ⁸⁶

Yet if public display is one dimension of scientific activity, private experiment is another, earlier, phase of the process.Footnote ⁸⁷ Again, Esdaile was also very aware of this aspect. ‘Great weight,’ he wrote,

Unlike Faraday, who conducted these experiments in the seclusion of his basement laboratory, Esdaile needed to conduct his early experiments in the presence of a limited set of hand-picked witnesses with the appropriate professional and social credentials to testify that ‘[n]o “hocus pocus”, no pretensions to exclusive powers, no attempts at concealment, are resorted to’.Footnote ⁸⁹ It is important to point out here that these audiences were not composed purely of ‘Indian viewers’, as his postcolonial critics imply. On the contrary they were mixed, picked each time from amongst his European and South Asian medical colleagues, colonial administrators, European missionaries and the Bengali elite – in short, the upper echelons of the population on both sides of the colonial divide.

But what of the ‘work meeting’ with the Bengali magician which this paper began with – which again was overseen by a witness of legal standing, the deputy magistrate of Hooghly, Baboo Essanchunder Ghoshaul? To make sense of this meeting, it is necessary to remind the reader that although Esdaile learned about mesmeric phenomena purely through reading about it, and that too rather late in his Indian career, he had no first-hand knowledge of the material operations and gestures necessary to induce a trance. Nor did he have any mesmeric practitioners whom he could directly watch to learn its techniques, unlike Braid and Elliotson, who, as already mentioned, were introduced to mesmerism by directly watching French demonstrators – Dupotet and Lafontaine respectively. Esdaile thus had to reconstitute all the gestures and the entire procedure by imagining them purely from published reports. And even though there was at least one practical manual for the purpose – Joseph Philippe François Deleuze's Instruction pratique sur le magnétisme animal (1825) – he himself ‘had never seen anyone mesmerised, nor read a mesmeric book’.Footnote ⁹⁰ Even if he did, it is doubtful that he would have been able to successfully translate the instructions effectively. Indeed, an influential body of scholarly literature has convincingly shown the limits of transmission of knowledge through the written word alone. Thus the tacit and gestural knowledge or skill sets needed to make knowledge operational in many cases are not exclusively verbal and necessitate sensorial communication through the presence of a skilled person.Footnote ⁹¹ Esdaile's ‘work meeting’ with the Bengali magician is, then, to be understood as a private, or ‘backstage’, encounter, prior to both the ‘frontstage’ public performance and the ‘first experiment’. It was a means of certification, again in the presence of a judicial witness, of the do-it-yourself procedures that Esdaile had laboriously worked out during his initial experiments. Since he was convinced of ‘the identity of the two processes’, the success of this comparison and the model of translatability on which it was premised would, among other things, legitimize the interoperability of mesmerizers he was to use in his surgery.Footnote ⁹² Indian magic could now be justifiably hospitalized.

However, Esdaile was not only seeking to establish his procedure and equivalence as valid knowledge. Indeed, by gathering as many witnesses as possible from both sides of the colonial divide, and publishing his accounts in professional medical journals as well as in those specializing in mesmerism, in the Indian and British press and in pamphlets and books for the British public, Esdaile was simultaneously attempting to breach the medical establishment's exclusive authority on deciding what counted as legitimate in medicine and surgery. He thus sought to mobilize a manifold of heterogeneous allies with a convergent interest in his brand of mesmeric anaesthesia. This involved unsettling established boundaries across a multitude of domains: between practices sanctioned by the medical establishment on the one hand, and mesmerism, superstition and magic on the other; between specialist and general publications; between medics and laypersons; between colonizers and colonized; between tropics and temperate zones; between European and Indian racial identities; between local and universal; and treating patients’ subjective accounts and professional expertise on par – a way of reshuffling the pack of entities, both scientific and extra-scientific, in order to create a new set of boundaries. It was for this reason that Esdaile sought to have officials from the judiciary present at every step and invest his witnesses’ testimonies with a legal status. This implied adding the dimension of judicialization to public displays of science. Lord Dalhousie's testimonials gave extra weight to the whole.

Esdaile thus hoped to get mesmeric anaesthesia recognized as a global practice, valid as much for ‘feeble and ill-nourished’ Indians and Africans with a ‘depressed state of the nervous system’ as for Europeans – on condition that they ‘condescend to return for a moment to the feet of their mother Nature’. At times, ‘simple, unsophisticated children of nature, neither thinking, questioning or remonstrating’, were far superior to Europeans, those ‘unnatural children, left to our self-sufficiency and artificial resources’.Footnote ⁹³ Public performances which mobilized witnesses from both sides of the colonial divide, alongside his concerted efforts at publishing, were also clearly part of his strategy to ensure the circulation of his mesmeric practice beyond colonial India, to the imperial metropole and the empire beyond.

Nonetheless, if Esdaile held an unwavering belief in the anaesthetic powers of mesmerism and its myriad global avatars, and was a passionate proponent of its cause, he was also very much part of the colonial order, and crucially dependent on it for advancing his enterprise, and his career. If at times he disturbed the colonial order, he certainly did not seek to destroy it, believing as he did in the benevolent superiority of Europe. In introducing mesmerism as an anaesthetic, Esdaile also sought to display the genuine concerns that he, as a representative of a colonial power, had for the well-being of its subjects, which in return ensured their submission and respect – a crucial dimension, it must be remembered, of modern science.

These are just some of the many paradoxes and contradictions of this entangled tale. But it was not the asymmetries of power and racial prejudice that confined this knowledge to the colonial margins. On the contrary, these were, as we have seen, conspicuously mobilized by Esdaile in his attempt to bring mesmeric anaesthesia to British-run hospitals in India and into mainstream Victorian science.

To sum up, this article has attempted to show that knowledge flows and the circulation of scientific practices have several different dimensions. First, this movement is not self-evident. It involves investments and consciously crafted strategies by scientific actors to continuously unpack what ostensibly moves as a black box in order to transform and reconfigure it for their own purposes. We see this in Elliotson's and Braid's appropriation of French mesmeric practices, and in Esdaile's adoption of Indian magic (a traditional relief for many ailments and pain) towards their respective anaesthetic ends. By positing deep similarities with magical practices the world over, Esdaile further sought to globalize mesmerism. We saw also that the successful circulation of practices crucially depends on the movement or adaptation of tacit knowledges on which they are based, which can potentially be replaced by other tacit knowledges on condition that equivalences be established between them. Finally, public displays can be used not just for certification but, by judicializing them, also to fight a recalcitrant medical establishment in India as well as in Britain. All these dimensions underline the fact that to understand science and its dynamics, we as historians of science cannot simply focus on knowledge practitioners, their texts, instruments and practices, but must also take into account the social, cultural, political and legal dimensions within which their practices are situated. These not only provide a context, a passive backdrop, to scientific activity, but, as we have seen, also are themselves actively mobilized and reconfigured in the construction and circulation of knowledge.
