DISEASES OF HORSES. 691 



Mix, and when cool give, as a drench, at one dose. After 

 three or four hours, 



Take Sweet Spirits of Niter 2 ounces. 



Laudanum, ....... 1 ounce. 



Water, \ pint. 



Mix and give at one dose. If this is done in the beginning, 

 it may arrest the attack. Give nitrate of potash, four drams, 

 three times a day, in the food, drink, or in a drench of cold 

 water; and bathe the nostrils with warm water, or cause steam 

 to be breathed, but not too hot. If there is a cough, bathe the 

 throat with the ammonical liniment (see index), or 



Take Mustard, powdered, ..... 3 ounces. 

 Water, hot, 1 quart. 



Mix and bathe the throat with it. Give loosening food. If 

 the discharge from the nose continues too long, give sulphate 

 of iron, two drams, twice a day; or chlorate of potash, two 

 drams three times a day ; or sulphate of copper, one dram, 

 three times a day, and after giving any one of these for a week, 

 it is best to change to some other. 



Congestion of the Lungs. This consists of an increased 

 amount of blood in the lungs, which interferes with the breath- 

 ing. It is the most common disease of the lungs, and goes be- 

 fore inflammation of the lungs. 



CAUSES. Driving an animal fast, when in a weakened con- 

 dition, is the most common cause. It follows influenza and 

 catarrh, and is sometimes caused by breathing impure air, and 

 possibly by a draft of cold air. A bloated condition of the 

 bowels which greatly interferes with the breathing may cause it. 



SYMPTOMS. If it is caused by over exertion, the animal will 

 be sluggish, will tremble especially in the flanks and will 

 breathe with difficulty. The nostrils will be wide spread ; the 

 pulse quick and labored, and sometimes indistinct; the mem- 

 brane lining the nose and eyes will be red, and a peculiar gur- 

 gling noise can be heard by placing your ear to the side of the 

 chest. His ears and legs will be cold ; he persists in standing, 

 but may, in some cases, lie down, but soon jumps up again. 

 It is sometimes produced very suddenly.
