water. This causes great c-pprefsion of the chest, 

 and difficulty in breathing, and a rupture of the 

 air-cells is the consequence. Thefe ruptured air- 

 cells form on the surface or edges of the lungs, and 

 are never completely emptied in expiration. 

 When this is the case, the animal not being able 

 to expel the air at one expiration, another imme- 

 diately takes place, and is attended with a very 

 high rising of the flank, which suddenly falls. 

 t This action goes on in regular succefsion. 



It is observable, that large quantities of wind is 

 found in the intestines of broken winded horses, 

 which may probably be owing to the great and 

 long-continued action of the belly. 



From a consideration of the causes of broken 

 wind, it must evidently appear, that it is an incur- 

 able disease, and our intention must be to mitigate 

 it as much as pofsible. This is best done, by giv- 

 ing the animal small quantities of the most nutri- 

 tious food and water at a time, and often, in the 

 the day ; by these means preventing, as much as 

 pofsible, prefsure on the chest, to which may be 

 added occasional doses of gentle purging medicines, 

 to keep the body open.
