tlu'in ami they do not sweat no maiter how hard or fast you drive 

 them on a hot summer day. 



Causes. The causes of this trouble are generally by I KM ng 

 cooled off too quickly, by being watered or stood in a draught 

 when very hot from a hard drive. It is caused more readily in 

 hor,ses not acclimated, or when the animal is not well. Northern 

 horses that are fed corn all summer, and worked hard in the hot 

 sun, are very liable to suffer from this trouble. 



Symptoms. Perhaps the first thing noticed will be dullness of 

 the animal, and no sweating. When driven, the animal will 

 breathe very fast and almost suffocate, but does not sweat. The 

 pores of the skin become blocked up and the nerve centres de- 

 ranged, and the waste and poisonous material that should come 

 out with the sweat remains in the system. The blood becomes 

 impregnated with this effete 1 material, and on going to the lungs 

 to be purified it gives extra work to the lungs, thus the cause of 

 the panting breathing and suffocation. An animal in this con- 

 dition is very easily overcome by the heat and subject to sun- 

 stroke. 



Treatment. In the treatment of this trouble, the great object 

 in view is to promote the secretions of the skin. If the animal 

 is much exhausted, and breathing fast, give the following: 



Sweet nitre 1 ounce. 



Alcohol 3 ounces. 



Water 1 pint. 



Mix, and give as a drench, and repeat every hour until 

 relieved. 



Give a change of feed; feed oats and bran, but no corn; give 

 the animal a good bath, and put three or four blankets on him
