DISEASES OF HORSES AND CATTLE. 159 



head lie flat. If there is cold water near at hand, 

 that can be dashed over the head and neck; in a 

 minute or two the animal will be all right. I have 

 found the attacks fewer when the animal got a 

 dose of physic occasionally; aloes is the best 



Congestion of the Brain. — This is usually caused 

 from injuries, such as the animal striking its head 

 hard against the top of a door as in coming out or 

 going into a car. I have seen several cases of this 

 kind, and they may be severe enough to cause rup-

 loud and rough. If the animal's head is raised, 

 it will throw it into spasms for a few minutes, but 

 soon gets back to the sleepy state, and if- it does not 

 turn into inflammation, the animal will likely die 

 in a comatose state, or there may be a few convul- 

 sions before death. Cattle in this condition will 

 stand for hours with their heads pressed hard

Treatment: Give a large dose of physic, one 

 ounce of aloes and two drams of calomel, made in-
