The changes that occur in the liver are not such as would 

 attract the attention of the average observer. 



The kidneys in very acute cases frequently have numerous small 

 blood points scattered over the surface, giving to the organ a 

 speckled, ''turkey egg" appearance. These small hemorrhages 

 are more numerous on the lower surface. On cutting into the 

 cavity of such kidneys, blood clots are often found. In mild or 

 chronic cases the kidneys appear normal. The bladder may also 

 be the seat of extensive hemorrhage, especially on the mucous 

 surface. 



In some animals which have died in the same herd, as those 

 showing the hemorrhagic conditions mentioned, the outer surface 

 of all organs examined may appear quite normal, and no suspicion 

 of cholera would be aroused; but on examination of the mucous 

 surface of the stomach and intestines positive signs of cholera are 

 often found. 



Remove the stomach and intestines and make an examination 

 of the inner walls. This is best done by stripping away the fat 

 which holds the coils of intestines together, then with a knife or 

 a pair of scissors cut open lengthwise portions of the large intes- 

 tine, beginning with the blind gut and continuing some distance 

 along the large intestine. Wash away the dung carefully, with- 

 out scraping the surface of the gut. The mucous surface of these 

 parts in some animals that die of cholera appear to be in a healthy 

 condition; in other cases, however, there will be seen, scattered
