 brief description of the post mortem appearances: 



Autopsy notes. — No. 152. — Skin of limbs and abdomen dotted with purple spots; 

 on abdomen general reddening. Points of extravasation and ecchymosed spots 

 throughout the subcutaneous connective and fatty tissue and on gastro-splenic 

 omentum. Superficial inguinal glands greatly enlarged and congested. Spleen en- 

 larged, filled with blood, and very soft. Petechias on epicardium. Numerous lobules 

 of the lungs collapsed. Glomeruli of kidneys appear as deep red petechia3. In cae- 

 cum and upper portion of colon extensive and deep ulcers. A few in the ileum near 

 the valve. The mucosa of the stomach, small and large intestine, thickly covered 

 with dark red points or petechias. 



No. 167. — Dying, and hence killed by a blow on the head. Spleen swollen, friable; 

 epicardium dotted with points and spots of extravasation. In lungs a few collapsed 

 lobules. Lymphatic glands generally very deeply congested, similarly the mucous 

 membrane of fundus of stomach and the kidneys. Large ulcers in caecum and upper 

 portion of colon. 



No. 168. — Subcutaneous and subperitoneal tissue contains numerous ecchymoses 

 from i to f inch in diameter. Spleen enlarged , gorged with blood, friable. Petechiae 

 on epicardium. Lungs not collapsed; its parenchyma contains numerous deeply 

 congested areas from i to i inch in diameter. Eadneys enlarged, with extravasations 

 on surface and in parenchyma. Cortex of lymphatics in general deeply* congested. 

 Extensive, almost continuous, ulceration of caecum and upper portion of colon, in 

 part blackish, the remainder of the large intestine being the seat of severe inflam- 

 mation and extravasation. Mucous membrane of stomach similarly involved. 



No. 175. — Subcutaneous tissue dotted with pale red spots. Tumor at the place of 

 the first inoculation firm throughout, pale yellowish. Superficial inguinal glands, 

 as well of those of thorax and abdomen, with purplish cortex. Spleen tissue still 

 tu-m, dotted with numerous bright red points, but shghtly enlarged. Beneath the 

 entire epicardium and endocardium many extravasations. Cajcum and upper por- 

 tion of colon extensively ulcerated. Serous surface of large intestine dotted v.ith 

 extravasations. 



No. 158.— Subcutaneous fatty tissue deeply reddened. Spleen shghtly enlarged. 

 Lymphatics in general with deeply congested cortex. Adhesive peritonitis matting 

 the various viscera together and to abdominal walls; fibrinous and serous exudate 

 abundant in the abdominal cavity. A few lung worms present. Caecum and colon 

 extensively ulcerated; rectum congested. Serous surface of this tract dotted with 

 exti-avasations. Fundus of stomach deeply congested. 



No. 176.— Shght reddening of skin and subcutaneous fatty tissue. Cortex of lym- 

 phatic glands in general deeply congested. Spleen much enlarged and surface dotted 

 with numerous bright red elevated points. A few petechiee on endocardium and 

 epicardium. Lungs deeply congested throughout; kidneys likewise inflamed. Stom- 

 ach shghtly reddened at fimdus. Small intestine also slightly congested. Serosa 

 of large intestine dotted with extravasations. The mucosa of c^cum and small 

 portion of colon one mass of necrosed tissue. Walls thickened. 



No. 189. — Extensive and deep reddening of skin of abdomen, throat, and limbs. 

 Subcutaneous tissue only shghtly reddened; spleen enlarged, gorged with blood, 

 friable. Besides the general congestion of the lungs there are small darker areas, 

 representing hepatized lobules. Bronchial glands and those along lesser curvature 

 of stomach swollen and gorged with blood; the other lymphatics only moderately 

 congested. Besides a small number of ulcers throughout the large intestine the 

 mucous membrane is deeply congested and dotted with occasional hemorrhagic 

 points. Kidneys extensively inflamed; on section the cortex shows extravasations. 



No. 190.— Considerable reddening of the skin of abdomen and ventral aspect of 

 limbs, very shght in subcutaneous tissue. Spleen greatly enlarged; dark pm-ple;
