Treatment. — If more than one animal in a herd becomes 
affected and after examining the teeth you find nothing wrong 
with them and you cannot see the mark of any injury outside 
around the jaws, and if they are not sore to handle, then be 
suspicious of this disease. Separate the affected animals from 
the sound ones and treat as follows: 
Give a full grown animal two drams of iodide of potas- 
sium, night and morning, on the tongue with a spoon or in 
the drinking water. Continue this treatment until there is a 
watery discharge from the eyes and the skin takes on a 
scurfy appearance. When this takes place discontinue for a 
few days — six or seven — then repeat until the same conditions 
reappear. In severe cases it is necessary to repeat four or 
even five times. In the majority of cases it is necessary in 
addition to this to blister the lump once a month with iodine 
omtment during treatment. 
Should this fail it is best to destroy the animal and burn 
the carcass, as there is danger of communicating the disease 
to others of the herd. The meat should not be eaten, as there 
is grave danger of communicating the disease to those who 
eat it.
