REPORT OF THE BUREAU OF ANIMAL INDUSTRY. GO 



inches of mucosa in fundus of stomach. Large intestine contains a 

 semi-liquid mass, chiefly earth. Four large ulcers in caecum, one of 

 them at least 1 inch across, covered by a yellowish slough; the peri- 

 toneum covering it is thickened and inflamed. In upper colon there is 

 considerable necrosis, involving the epithelium in patches. Lungs 

 normal, excepting the right ventral lobe, which is solid. Bronchi 

 and air cells of this lobe completely occluded by plugs as with No. 

 2; surface bright red, mottled with yellowish pointsthe ultimate 

 air cells filled with the cellular exudate. Subpleural ecchymoses 

 over both lungs. From the spleen a liquid and a gelatine culture 

 contained only hog cholera bacteria. They were very numerous in 

 cover-glass preparations from this organ. 



A rabbit inoculated from the consolidated lung tissue died on the 

 seventh day. At the point of inoculation a pasty mass extends to 

 abdomen, only subcutis involved. Spleen engorged. Single acini 

 and groups in the liver are completely necrosed, yellowish white. In 

 both organs hog cholera bacteria. Cultures from spleen pure. 



November 25. No. 15, black and white male, died yesterday morn- 

 ing. Redness of skin of abdomen, throat, and limbs. Superficial in- 

 guinals hemorrhagic. Spleen very large, gorged with blood. Lungs 

 normal, excepting a few lobules at the caudal border of principal 

 lobes, which are reel, collapsed, and contain lung worms. Pericardium 

 contains deep-colored serum and coagula; left auricle dotted with 

 petecchiae. JBronchial lymphatics hemorrhagic. Liver slightly cir- 

 rhosed. Cyst in right kidney one-half inch in diameter. Fundus of 

 stomach intensely congested, similarly the caecum and colon; no ul- 

 cers. Lymphatics of meso-colon hemorrhagic. A beef-infusion cult- 

 ure from a bit of spleen contains the motile hog cholera bacteria only. 

 A gelatine culture became liquefied by the heat of the laboratory; 

 no bacteria seen on a cover-glass preparation of spleen. 



No. 16, black and white female, died last night. Skin and spleen 

 as in previous case. The small ventral lobe of both lungs collapsed, 

 lungs otherwise normal. Liver in advanced stage of sclerosis; stasis 

 of portal circulation. Lymphatics of abdomen as in No. 15. Fundus 

 of stomach slightly reddened; one ulcer three-fourths inch across. 

 Extensive necrosis of mucous membrane in colon and rectum, slight 

 in csecum; wherever the membrane is free from a slough it is deeply 

 congested. Numerous hog cholera bacteria and some large (butyric) 

 bacilli in spleen. A beef infusion and a gelatine culture contain 

 them. From a bit of collapsed lung tissue a plate culture is made 

 and a rabbit inoculated. The plate contains in two days about six 

 to seven liquefying and a largo number of non-liquefying colonies, 

 the latter made up of motile hog cholera bacteria; the rabbit died on 

 the seventh day. Spleen very large, friable; contains large numbers 

 of hog cholera bacteria. On left lobe of liver an area of necrosis one- 

 fourth inch by three-fourths and one-sixteenth inch deep. On the 

 right lobe only three or four acini necrosed. Pylorus and duodenum 

 covered with hemorrhagic dots and patches. Culture from spleen 

 pure. 



November 26. No. 17, female of medium size; died suddenly this 

 morning without previous illness. Subcutaneous fat abundant. 

 Spleen moderately congested. Petecchiae in cortical portion of kid- 

 neys. Fundus of stomach slightly reddened. In lower ileum patches 

 of congestion. Scattered peteccliise in mucosa of large intestine; con- 

 tents normal. Glands of mesentery and meso-colon with cortex hem- 

 orrhagic. Large quantity of blood-stained serum in thorax. Fi-
