In Quain’s “Dictionary of Medicine,” ii., p. 1063, Dr. Gowers says:--“The state now designated hypnotism is really induced trance, and trance has been accurately termed ‘spontaneous hypnotism’.... “The mental functions seem, in most cases, to be in complete abeyance. No manifestations of consciousness can be observed, or elicited by the most powerful cutaneous stimulation, and on recovery no recollection of the state is preserved. But in some cases volition only is lost, and the patient is aware of all that passes, although unable to give the slightest evidence of consciousness.... “In the cases in which the depression of the vital functions reaches an extreme degree, the patient appears dead to casual and sometimes to careful observation. This condition has been termed ‘death-trance,’ and has furnished the theme for many sensational stories, but the most ghastly incidents of fiction have been paralleled by well-authenticated facts.

In a well-authenticated case of death-trance the intense mental excitement produced by the preparations for fastening the coffin lid occasioned a sweat to break out over the body.” [CASE OF BENJAMIN DISRAELI.] Many notable men have at one time or another been subject to this disorder.

The _Lancet_ of December 22, 1883, pp. 1078-80, contains particulars from the pen of W. T. Gairdner, M.D., LL.D., etc., Professor of Medicine in the University of Glasgow, of a remarkable case of trance, extending continuously over more than twenty-three weeks, which attracted a considerable amount of notoriety at the time and led to an extensive discussion. In his comments upon the case, the author continues, in the issue of January 5, 1884, pp. 5, 6:--
