EEPOET OF THE BUEEATJ OF ANIMAL INDUSTRY. 73 



in caecum. . About one-third of the ventral lobe of each lung and a 

 few lobules of the right principal lobe collapsed. Lungs otherwise 

 normal. In a beef infusion culture from the spleen both hog cholera 

 and butyric bacteria were present. A gelatine culture contained but 

 two colonies. From a bit of collapsed lung tissue a plate culture 

 was made and a rabbit inoculated. On the plate about fifteen col- 

 onies of hog cholera bacteria appeared. The rabbit died on the fif- 

 teenth day. Bare indications of necrosis in liver. Spleen very large. 

 Both organs contain a moderate number of hog cholera bacteria. 

 A roll culture from the spleen is pure. 



No. 29, large black male, died about thirty-six hours ago. Tem- 

 perature below freezing point. Skin deeply reddened over entire 

 ventral aspect of body. Superficial inguinals enlarged, slightly con- 

 gested. Spleen very large (about 14 inches long), very soft and 

 friable. Slight sclerosis of liver and old perihepatitis. Eetro-peri- 

 toneal glands with cortex hemorrhagic. Cyst in right kidney. 

 Slight ecchymoses in fundus of stomach. Valve and patch of mu- 

 cous glands in csecum very dark with pigment. Slight superficial 

 ulceration in csecum and upper colon. Lungs and heart normal. 

 Both gelatine and beef infusion cultures contain hog cholera bacteria. 

 In the former the colonies are very numerous. 



No. 30, small black male, died thirty-six hours ago. No redden- 

 ing of skin. Superficial inguinals and spleen but slightly enlarged. 

 Peritonitis. Petecchiae under serosa of small and large intestines 

 and bladder. Moderate amount of fibrinous exudate. Valve com- 

 pletely ulcerated, ulcer deep. One near valve has caused thickening 

 of serosa of intestinal wall. In caecum an extensive patch of ulcera- 

 tion; in colon a few ulcers and numerous punctiform hemorrhages. 

 Right lung completely adherent to costal pleura by means of fibrous 

 tissue. A small ventral portion of principal lobe of loft lung is air- 

 less, pale red, mottled with yellowish points. Air tubes and vesic- 

 ular portion occluded with dry cylindrical plugs. A culture in gela- 

 tine from the spleen develops numerous colonies in each track of 

 the wire. A liquid culture contains the butyric bacillus also. A 

 bit of the solidified lung tissue was used for a plate culture and to in- 

 oculate a rabbit. The plate developed countless colonies of hog 

 cholera bacteria as tested by other cultures. The rabbit died on the 

 tenth day. The spleen was enlarged, the liver full of centers of ad- 

 vanced necrosis, involving one to three acini; hog cholera bacteria 

 very numerous in both organs. 



December 3. No. 31, small black and white female, died yesterday. 

 Well marked odor of decomposition. No skin discoloration. Spleen 

 but slightly enlarged. Lymphatics in general with hemorrhagic 

 cortex. Liver in state of advanced sclerosis. Stomach normal. A 

 few large old ulcers and a considerable number of small ones 

 throughout cgecum and colon. Mucosa itself pigmented with patches 

 of fresh congestion. Lungs normal. A liquid culture from the 

 spleen contains only butyric bacilli. 



No. 32, small black and white female. No skin discoloration. Lym- 

 phatics, including inguinal, bronchial, and peritoneal with more or 

 less hemorrhagic cortex. Spleen engorged. Liver sclerosed. Kid- 

 neys with numerous petecchise throughout cortical portion. Stomach 

 pale. Several large old- ulcers in upper colon. Caecum and colon 

 pigmented. Lungs normal with exception of a few collapsed lobules 

 in ventral lobes. Both a gelatine and a beef infusion culture contain 

 hog cholera bacteria. Colonies very few.
