wooden tongue. In this case the animal falls off in condition, 

 because of not being able to eat, and soon dies. 



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 

 ointment 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.
