The liver was congested, softened, shrunken in protracted 

 cases, colored of a deep yellow especially in the interior, and 

 with gorged biliary radicles so that the acini stood out very 

 prominently. The gall bladder was usually well filled with a 

 thick, fiocculent bile, yellowish green, blackish green or choco- 

 late color. 



The spleen appeared shrunken, somewhat spherical, 2 to 3 ozs., 

 firm, and with a dark, reddi.sh brown pulp. 



The kidneys were greatly enlarged, weighing 12 to 16 ozs., 

 dark red or bluish black, friable, and on .section exuding freely a 

 bloody or chocolate-colored liquid. The capsule was easily de-

 urine, but was .sometimes empty. 



The heart cavities were empty or contained small diffluent

The patient usually dies in a state of collapse which has lasted 

 for several hours, yet in certain cases it is preceded by a convul-

It is certain that the affection may appear in a mild form, as 

 sheep slaughtered in apparent health are found to show the gen- 

 eral icterus, the congested liver, and the leucocytosis with crena- 

 tion of the red globules which characterize the disease. The 

 icteric carcasses are said to be recognized and condemned at 

 Kansas City and Omaha. 



The duration of the affection is from i to 5 days, though it 

 may last longer, and severe attacks usually end in death. 



^he. prevention of this disease can, as yet, be based only on the
