11. Vomiting. 



This is sometimes met with in cattle, but never in horses. 



Causes. — It is generally caused by some irritation of the 

 fourth, or true digestive part of the stomach, or it may be 

 caused by eating some bones, old clothes, or a boot, or some- 

 thing of that kind. Sometimes it is caused by nails which 

 are taken into the rumen with food. Often after an animal 

 is slaughtered there are nails and rubbish found in the 

 stomach. 



Treatment. — Give a physic consisting of 



Epsom Salts 1 pound. 



Brown Sugar ^2 pound.

Bicarbonate of Soda 2 dessertspoonfuls. 



Mix and ^ive as a drench every second day until the
