70 EEPOET OF THE BTJBEAU OF ANIMAL INDUSTRY. 



brinoTis deposit on pleura; lungs partly expanded; cephalic half of 

 right lung solid, blackish; air- tubes and alveoli filled with extra- 

 vasated blood. Interlobular tissue distended with blood-stained 

 serum (pulmonary hemorrhage). Left lung in the same condition. 

 Trachea full of reddish foam. Blood and fibrinous coagula in peri- 

 cardial cavity. Beef infusion, into which a bit of spleen was placed, 

 remains sterile; also a tube of gelatine inoculated from the spleen 

 with platinum needle. In a cover-glass preparation of the spleen 

 large (butyric ?) bacilli. 



No. 18, small female, died last night. Buzzards have consumed 

 thigh muscles. Diffuse reddening along median line of abdomen. 

 Hemorrhagic spots one-eighth to one-fourth inch across, subepider- 

 mal, chiefly on ventral aspect of limbs; subcutaneous and subperi- 

 toneal ecchymoses. All abdominal lymphatics with cortex infiltrated 

 with blood. Serosa of large intestines as if sprinkled with fresh 

 blood; several subserous hemorrhagic spots one-half inch across on 

 diaphragm, along inferior vena cava, common bile duct, and gall 

 bladder; also under mucosa of the whole length of small intestine, 

 throughout cortical portion and between pelvis and medullary por- 

 tion of kidneys. Fundus of stomach one mass of petecchise and 

 larger extravasations. One ulcer in csecum, old, with indurated base. 

 Valve and the patch of mucous crypts at its base ulcerated; depth 

 of ulcer indurated, consisting of a tough, pale tissue. Small old ul- 

 cers in upper colon. Lungs dotted with small hemorrhages, chiefly 

 subpleural. Three, or four hemorrhagic patches under costal pleura 

 of each side. Lung tissue normal, excepting the base of right ven- 

 tral and the tip of left ventral lobe, which are collapsed. Hemor- 

 rhages under epicardium over entire heart; left auricle one ma'ss of 

 ecchymoses. Coagula of fibrin in auriculo-ventricular groove. 



Through an oversight the cultures from this animal and the one 

 following were both numbered the same, so that it was impossible to 

 identify them. A liquid culture from each was made by adding a 

 bit of spleen tissue. A gelatine culture from each was made simply 

 with platinum wire. One tube of infusion contains hog cholera and 

 butyric bacteria; one tube of gelatine contains immense numbers of 

 hog cholera colonies. The other two tubes remain sterile. A rabbit 

 inoculated from the collapsed lung tissue remained well for a month 

 after. A plate culture from the same contained about six colonies, 

 evidently of hog cholera bacteria. 



No. 19, small male, died last night. Diffuse reddening on abdomen 

 along median line. Superficial inguinals very large, pale, cedema- 

 tous; peritonitis; feeble adhesion of coils of intestine to ventral wall 

 and or lobes of liver to one another. Slight fibrinous deposit on 

 intestines. Liver sclerosed. Lymphatics hemorrhagic. Cortex of 

 kidneys dotted with extravasations. Mucosa of large intestines of a 

 dark slate color; it is dotted with closely-set conical elevations, tough, 

 whitish, about one-eighth inch high * and one-sixth across. When 

 scraped away a depressed pale pink, sharply-outlined spot remains. 

 Microscopic examination of th intestine showed that these elevations 

 correspond to amorphous masses, which failed to become colored on 

 applying the ordinary staining agents. They covered portions of 

 the mucosa which were either wholly or partially necrosed and in- 

 capable of being stained. In some places the outline of the tubules 

 could still be discerned. On applying Weigert's fibrin stain, long 

 meshes of fibrin corresponding in general to the outline and position 

 of the destroyed tubules appeared. Valve thickened and completely
