 a half pint of water. In about a week, a condition 

 known as "iodism" is set up. This is shown by a dis-

 condition of the skin, especially of the neck, as if bran 

 were scattered at the roots of the hair. When iodism is 

 noticed, the medicine should be stopped. The tumor in 

 most cases gradually disappears, and the animal makes

may be repeated in two weeks. An animal with a tumor 

 that is discharging should not be allowed to run with

 may be taken as food, and, entering a wound, is capable 

 of growing and causing the disease. 



If the tumor is not large, or is not discharging so 

 as to affect the general health, the flesh of the animal 

 is not considered to be dangerous for food.
