74 REPORT OF THE BUREAU OF ANIMAL INDUSTRY. 



No. 33, large black and white male; said to have died last night. 

 Advanced post mortem changes. No examination made, excepting 

 to see the condition of lungs, which were healthy. 



No. 34, medium-sized white, died last night. Considerable red- 

 dening over ventral aspect of body. Inguinals reddened on section. 

 Small quantity of dark-colored serum and numerous yellowish flaky 

 coagula attached to abdominal organs. Spleen very large, dark, 

 friable. Liver cirrhosed. Kidneys with cortical portion thickly 

 dotted with petecchise, hemorrhage into pelvis. Lymphatics in ab- 

 domen with cortex more or less hemorrhagic. Extensive and deep 

 ulcer ation in large intestines; in caecum and upper colon as large 

 patches, in lower colon as small ulcers. The mucosa which is not 

 destroyed is deeply congested. Stomach along fundus deeply red- 

 dened. Extensive fibrous adhesions of left lung to walls of thorax. 

 Collapse involves ventral, cephalic, and portions of principal lobe of 

 right lung, and small portion of principal and ventral lobe of left 

 lung. Extensive muco-purulent secretion in trachea, bronchi, and 

 subdivisions throughout both lungs. Bronchial glands with cortex 

 hemorrhagic. A beef infusion culture from the spleen contains hog 

 cholera and butyric bacteria. In the gelatine culture each track 

 of the wire contains countless colonies of what are shown under the 

 microscope to be motile hog cholera bacteria. From a bit of col- 

 lapsed lung tissue a plate culture was made and a rabbit inoculated. 

 The plate develops countless non-liquefving colonies. The rabbit 

 died on the eighth day. Spleen enlarged. Liver infested with coc- 

 cidia. A slight amount of coagulation-necrosis. Hog cholera bac- 

 teria in both organs and in cultures from the spleen (both gelatine 

 and liquid). 



December 5. No. 35, small black and white female, died yester- 

 day. Redness of skin over abdomen and inside of limbs. Spleen 

 enlarged, slightly congested. Lymphatics with cortex infiltrated 

 with blood. Large quantity of blood-stained serum in abdomen. 

 Liver sclerosed. A few scattered petecchise in cortical portion of 

 kidneys. Mucosa of colon pigmented; a few small ulcers present. 

 Lungs normal, with exception of a few collapsed lobules in ventral 

 lobe of each lung. Dark-colored serum in pericardial cavity. The 

 spleen contains large numbers of butyric bacilli. A liquid culture 

 contains both hog cholera and butyric bacilli. A gelatine culture 

 remains sterile. 



No. 36, large black and white female, died yesterday. Lungs nor- 

 mal. Spleen. very large, dark, friable. Liver sclerosed; lymphatics 

 generally with cortex congested or hemorrhagic. Large number of 

 ulcers in caecum and colon; mucosa deeply congested. Prom spleen 

 countless colonies of hog cholera bacteria in a gelatine tube culture. 

 In a liquid culture the butyric bacilli are also found. 



No. 37, medium Jersey red and the last of a lot of seven, dead 

 forty-eight hours. This animal has been sick for some time; the 

 spleen was very large, gorged with blood. Lymphatics pale. Large 

 number of old ulcers, from one-sixteenth to !- inches across in 

 csecum and colon; mucous membrane generally pale. Of the lungs, 

 both ventral and a small portion of cephalic lobes with smaller 

 bronchi and alveoli plugged with dry catarrhal products. A liquid 

 culture from the spleen contains hog cholera and butyric bacilli. A 

 gelatine culture contains countless colonies. The spleen pulp on 

 cover-glass preparations shows many. From the diseased lung tissue 

 a rabbit was inoculated and a plate culture made. The latter de-
