The brain was moderately firm, and weighed forty-nine ounces and a half. The mucous membrane of the trachea was of a greenish color, probably due to post mortem change.

The liver was very flabby; it weighed forty-three ounces; the gall-bladder contained four drachms of bile. The spleen was firm and of a mahogany color; it weighed six ounces. The pancreas was healthy, and weighed three ounces. The cortical substance of the kidneys was pale, the pyramids purple, the pelves bluish; the kidneys weighed five ounces and a half each. The walls of the small intestine were quite thin; its mucous membrane presented a dark-purple congested appearance; Peyer's patches, which were not swollen, were of a dingy stone color, with central dots of pigment in the follicles composing the patches. The large intestine presented nothing remarkable except in its lower portion, where the mucous membrane was of a deep crimson color; there was no ulceration or exudation of lymph on its surface.—Assistant Surgeon Harrison Allen, U. S. A.⃰


⃰ 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.
