I have had a life which, for variety and romance, could, I think, hardly be exceeded. I have known what it was to be a poor man and I have known what it was to be fairly affluent. I have sampled every kind of human experience. I have known many of the most remarkable men of my time. I have had a long literary career after a medical training which gave me the M.D. of Edinburgh. I have tried my hand at very many sports, including boxing, cricket, billiards, motoring, football, aeronautics and ski-ing, having been the first to introduce the latter for long journeys into Switzerland. I have travelled as Doctor to a whaler for seven months in the Arctic and afterwards in the West Coast of Africa. I have seen something of three wars, the Soudanese, the South African and the German. My life has been dotted with adventures of all kinds. Finally I have been constrained to devote my latter years to telling the world the final result of thirty-six years’ study of the occult, and in endeavouring to make it realize the overwhelming importance of the question. In this mission I have already travelled more than 50,000 miles and addressed 300,000 people, besides writing seven books upon the subject. Such is the life which I have told in some detail in my Memories and Adventures.
