8. In some cases the eyelids become swollen so much 

 that the animal can hardly open the lids sufficiently 

 wide to see. Many cases are accompanied by a more or 

 less prominent swelling under throat or root of the 

 tongue, between the branches of the lower jaw. 



As a rule the sick animal becomes separated from the 

 rest of the herd ; if weather is warm it seeks the shade, 

 stands vdih arched back and shrunken abdomen, or lies 

 down from weakness. In cool weather, or during the 

 Avinter season, many cases perish largely from exposure 

 to cold nights and cold rains. 



EXAMINATION AFTER DEATH may help one in making 

 an accurate decisionin regard to the disease causing the 

 death of the animal. Post mortem conditions are some- 

 times quite characteristic and constant ; yet in some in- 

 stances some of the common characteristics may be ab- 

 sent or not sufficiently marked as to be recognized. The 

 condition of the carcass as to flesh will vary with the 

 length of time the animal was sick, and the type or se- 

 verity of the disease. As a rule a few days of high fever 

 that suspends all digestive action Tsill lead to rapid 

 emaciation. In cutting through the skin notice that 

 there is verv little blood in it or the tissue just under the 

 skin, and the small amount of blood in the skin is pale, 

 and does not readily coagulate. After opening the ab- 

 dominal cavity, examine the liver, the spleen, the kid- 

 nevs, the bladder, the stomachs, and the intestines. If 

 the animal died in one to three days after becoming sick 

 the liver may be very large — engorged with blood and 

 bile, giving it a rather dark brown color; but if the 

 animal lived a number of days after becoming sick the 

 liver will be engorged with bile and will have a deep 

 yellowish tinge ; this yellow color is very prominent upon 

 a cut surface of the liver. The gall bladder is usually
