⃰ September 14, 1864, Dr. Allen presented to the Pathological Society of Philadelphia a brief "Synopsis of Autopsies made at Lincoln General Hospital," to which the reader is referred.—(Proceedings of the Pathological Society of Philadelphia, in the American Journal of the Medical Sciences, January, 1865, page 133.) In this paper he analyzes the appearances observed in forty-one cases of diarrhœa and dysentery, thirty-five of fever, twenty-one of pneumonia, and five of diphtheria. The notes of Dr. Allen's autopsies, from which the accounts here presented have been condensed, were not contained in the case-books of Lincoln hospital turned in to the Surgeon General's Office at the close of the war, but have since been copied into them from the originals, loaned for the purpose.
