DISEASES OF THE HORSE. 97 



Heaves 



Are produced by driving the horse against a heavy current of air, 

 and inhaling an excess of air ; thus overcharging the lungs, they 

 become ruptured, and when once ruptured, can never be cured The 

 food should be well wet, so that he will inhale no dust while eating, 

 as it is very injurious. The dust of a threshing machine for one'

 three drams calomel, in one pint of linseed oil. Keep him in a com- 

 fortable box, feed him on whatever he can eat— bran mashes, boiled 

 oats, or, if he is very bad, give him a sloppy drink of oat-meal, rye- 

 meal, or linseed-meal, whichever he can take. 



Bots. 

 Bots are one of the natural appendages of the stomach of a horse 

 —as much so as his lungs, arteries, nerves, or any other essential part 

 of his vital organism. They never injure the horse. 



They have been placed in the stomach of all horses by nature, for 

 a specific purpose, and no horse can live without them in the stomach
