In 1927 Hilda M. Woods and I contributed to this Journal a study of some aspects of a syndrome called “Status Thymicus,” “Status Thymico-Lymphaticus” or simply “Status Lymphaticus.” We were moved by three considerations: (1) that Prof. H. M. Turnbull had placed at our disposal a long series of weighings of the Thymus, the alleged principal villain of the piece; (2) that every year a not inconsiderable number of deaths are put to the account of this syndrome; (3) that the first volume of Prof. J. A. Hammar's monograph on the Thymus had recently been published. Since our publication, the annual quota of victims shows no signs of diminution (Table I) and the second volume of Prof. Hammar's work has appeared.
