72 BEPORT OF THE BUREAU OF ANIMAL INDUSTRY. 



in a very dark rrmcosa dotted with, numerous punctif orm ecchymoses. 

 At root of left lung there is some collapse, extending slightly into 

 all lobes. Of right lung the ventral and cephalic lobes are collapsed, 

 with occasional emphysematous lobules interspersed. Lungs other- 

 wise normal. Extensive hemorrhage of both auricles in the form of 

 diffuse patches and petecchise. A gelatine and a liquid culture from 

 the spleen remain sterile. A plate culture made from a bit of col- 

 lapsed lung tissue contains a considerable number of colonies, which 

 are made up of bacteria resembling those of hog cholera, but differ- 

 ing from them in their manner of growth on gelatine, in beef infu- 

 sion, and in the absence of motility. A rabbit inoculated from the 

 same bit of lung tissue remains well. A plate culture from a bit of 

 normal tissue from the same lung contains but one colony. 



No. 24 died yesterday; medium-sized female. Spleen very large, 

 extends beyond median line. Lungs normal, excepting collapse of 

 a small portion of the right ventral lobe. Lymphatic glands in gen- 

 eral with hemprrhagic cortex, Csecum and colon very much con- 

 gested, ulceration superficial and slight. Entire fundus of stomach 

 of a uniform deep wine color, A gelatine and a liquid culture from 

 the spleen contain only motile hog cholera bacteria. In the former 

 the colonies are very numerous. The bacteria are demonstrated in 

 cover-glass preparations from spleen pulp. 



No. 25, medium sized black male, died yesterday. Spleen very 

 large. Subperitoneal tissue full of petecchia). Lymphatics with 

 hemorrhagic cortex. Hemorrhages under serosa of duodenum and 

 common bile duct. Valve completely ulcerated. Intestine other- 

 wise normal and feces dry, Lungs contain a large number of sub- 

 pi eural hemorrhages; parenchyma normal; epicardinm hemorrhagic. 

 Kidneys contain a specimen of kidney-worm (Sclerosfomapinguicola). 

 A gelatine and a beef infusion culture from the spleen became con- 

 fused with those of another pig (No. 435). to be described later on. 

 One set of cultures remained sterile; the other contained hog cholera 

 bacteria. In all probability the sterile cultures belonged to this 

 animal. 



December 2. No. 26, medium-sized female, died last night. Con- 

 siderable redness of skin over the ventral aspect of limbs and along 

 median line of abdomen. Spleen very large, blackish. Several 

 strong fibrous adhesions between costal and pulmonary pleura. Lung 

 tissue normal. Left kidney contains a small cyst. Large number 

 of round depressed ulcers stained yellow, most numerous in caecum. 

 One ulcer is one-half inch across, the inflammation extending to 

 serosa. Stomach very dark, pigmented along fundus. On a cover- 

 glass preparation from spleen numerous large bacilli (probably buty- 

 ric). They did not develop in the liquid and gelatine culture, which 

 latter contained only hog cholera bacteria colonies, very numerous 

 in each needle track. 



No. 27, small black male. Superficial inguinals enlarged, pale, 

 cedematous. Superficial ulceration and hemorrhagic changes in 

 caecum. Lungs normal. Post mortem changes too advanced for 

 cultures. 



No. 28, small female, died last night. Superficial ingninals with 

 cortex hemorrhagic. Spleen slightly enlarged. Minute hsemato- 

 mata on its surface. Slight sclerosis of liver. Left kidney contains 

 six cysts one-half inch diameter. Stomach in f undus some what con- 



fested. In large intestine, ulcers one-quarter to three-eighths inch 

 iameter, with adherent yellowish, projecting slough, most numerous
