BEPORT OF THE BUREAU OF ANIMAL INDUSTRY. 71 



covered by ulceration. Cephalic half of both lungs airless, affected 

 with broncho-pneumonia; catarrhal exudate filled alveoli and air 

 tubes. Epicardium dotted with hemorrhagic points. Slight, feeble, 

 pleural adhesions. 



For cultures from spleen, see No. 18. A rabbit inoculated with 

 lung tissue died on the fifth day. Spleen slightly enlarged; contains 

 many hog cholera bacteria. Gelatine culture contains very many 

 colonies of the same. 



No. 20, a large female. No skin lesions; a few strings of coagula 

 over coils of intestine; spleen small; base of pyramids of kidneys 

 much reddened; ileum dotted with subperitoneal hemorrhagic points 

 and patches; mucosa not affected; mesenteric glands with cortex 

 hemorrhagic. Large intestine empty, scattered ulcers one-eighth to 

 one-fourth inch across. Liver sclerosed. 



A beef-infusion culture inoculated with a bit of spleen tissue con- 

 tains hog cholera bacteria and butyric bacilli. A gelatine tube cult- 

 ure contains a few hog cholera colonies. 



November 29. No. 21, small Jersey red, female, died last night. 

 Skin deeply reddened along median line of abdomen. Large quantity 

 of blood-stained serum in peritoneal cavity. Serosa of ileum and the 

 mesentery completely covered with hemorrhagic points and patches. 

 Lymphatics of abdomen hemorrhagic throughout their substance. 

 Petecchiae in cortex of kidneys. Mucosa in fundus of stomach hem- 

 orrhagic. Mucosa of lower ileum a confluent layer of necrosed tis- 

 sue. Numerous round ulcers in caacum and colon; slough projects 

 slightly. Lungs hypostatic, interlobular spaces distended with coag- 

 ulated blood, most marked in dependent lobes. Simple collapse of 

 both ventral lobes and of the right principal near the root. Ventri- 

 cles of heart dotted with petecchise, auricles ' black, covered with 

 clotted extra vasated blood. Hog cholera bacteria present in cover- 

 glass preparations from spleen and in both gelatine and liquid cult- 

 ures. 



No. 22, male, Jersey red, died last night. Glands of abdomen with 

 cortex infiltrated with blood. Spleen engorged. A few hemorrhagic 

 patches in fundus of stomach. In caecum and colon ulcers about 

 three-eighths inch across; very thin, adherent, yellowish slough. 

 About one ulcer to 4 square inches of surface. Considerable blood- 

 stained serum in pleural cavities, hemorrhage in anterior half of left 

 lung, which is solid, blackish on section. Clots and reddish foam in 

 trachea and bronchi; hemorrhage seems somewhat older than in No. 

 21. Pleura of right lung roughened and parts adherent to chest wall. 

 Ventral lobe solid, bronchioles firmly plugged with dry catarrhal se- 

 cretion. Hog cholera bacteria on cover-glass from spleen pulp and in 

 a gelatine and liquid Culture made therefrom; only five to ten col- 

 onies in each track of the platinum wire. A rabbit was inoculated 

 from a bit of the solidified lung tissue and a plate culture made. 

 The latter develops numerous colonies of hog cholera bacteria. 

 The rabbit died on the thirteenth day. Numerous hog cholera bac- 

 teria in both organs. A gelatine culture from the spleen contains 

 the same organisms. 



No. 23, small black male. Buzzards had removed pectorals of one 

 side. Lymphatics congested, not hemorrhagic. Crowded petecchiae 

 in subcutis and beneath peritoneum of ventral abdominal wall. Spleen 

 very large, congested. Four or five small hemorrhages on diaphragm. 

 Mucosa of caecum and upper colon ulcerated in large patches. In 

 lower colon the ulcers are small, yellowish, depressed areas embedded
