IIQ NAVIN ON THE HOESE. 



breathino- of the patient, it will be seen that two efforts are 

 made to expel the air from the lungs. There is, generally, a 

 sort of dry, husky, gruntish cough, and both it and the heav- 

 ino- are grcatlv aggravated if the horse is exposed to any dust. 

 The belfy, in heaves, becomes enlarged, and the horse is said 

 to be pot-bellied. Indigestion, or dyspepsia, is a common ac- 

 companiment of heaves. The horse may be a great eater, 

 and the large quantity of food taken only aggravates the 

 trouble. The horse looks rough and stupid, and is generally 

 used up. He is of but little account for any purpose. 



Cmises.— The more common causes which produce heaves 

 are over-exertion and indigestion; and there can be no bettei 

 way of producing it than by putting the horse to severe laboi 

 or exertion on a full stomach. The race-horse and the car- 

 riage-horse are guarded against this accident by not being re- 

 quired to perform while the stomach is full or distended. It 

 may result from some other diseases. A running together or 

 rupturing of the iiir-cells of the lungs gives rise to this sort 

 of breathing. A. mere enlargement of the air-cells, or a puffy 

 condition of the substance of the lungs, will cause it. 



Treatnmit.—Tlisii treatment of the horse which will prevent 

 the occurrence of this disease is of more importance to be 

 attended to than the administration of drugs, with a hope of 

 curing it, after it has taken place: regular and moderate 

 feeding, and moderate exercise when the stomach is full; and, 

 when the labor is necessarily severe, let the food be of that 

 kind that is nutritious, but not bulky. The horse should not be 

 allowed to swell the stomach with water, after feeding— a habit 

 too prevalent in this country. Free room for action is neces- 

 sary to the health of the lungs, when the horse is at service, 

 and this they can not have, if pressed by a gorged stomach. 



Of course, many remedies have been recommended for 

 heaves, and I presume about the same want of success attends 

 all of them. The following may be used to relieve the horse, 

 or palliate the disease :
