over the windpipe and in the space between the lower jaws. Apply this 

 liniment once a day for two or three days. 



If the animal can swallow without much difficulty, give the following 

 as a drench, to be repeated every six hours: fluid extract hyoscyamus, 

 one dram; powdered chlorate of potash, two drams; molasses, two 

 ounces. 



Should great difficulty be experienced in breathing, do not attempt to 

 give drenches, but persevere in steaming the nostrils, and dissolve two 

 ounces of chlorate of potash in every gallon of water given. Even if 

 this is not swallowed and returned through the nose it will be of bene- 

 fit as a gargle to the pharynx. 



If breathing begins to be loud, relief is sometimes afforded by giving 

 as a drench two ounces of jaborandi in half a pint of water. If this 

 benefits, repeat the dose five hours after the first. This will cause a 

 free flow of saliva from the mouth within a half hour. 



Roaring This is caused by an obstruction to the free passage of the 

 air in some parts of the respiratory tract. This is really a symptom of 

 some ailment and not a disease of itself. There are many causes that 

 may induce temporary, intermitting or permanent noisy breathing; but 

 in nine out of every ten cases of chronic roaring, the cause is paralysis 

 of the muscles of the larynx. A skilled veterinarian who is able to de- 

 termine the cause of the trouble, may be able to benefit, but the result 

 is doubtful. 



Note. — An animal that is a roarer should never be used to breed 

 from, no matter how valuable the stock. This taint is transmittible, 

 and the offspring is born with a predisposition to this trouble. 



High. Blowing. This is a noisy breathing that is decidedly a nasal 

 sound, and must not be confounded with "roaring." Tbe sound is pro- 

 duced by the action of the nostrils. This is a habit and not an un- 

 soundness. In "roaring" when the animal is put to severe exertion the 

 sound increases, in "high blowing" the sound ceases. 



Whistling. This is one of the sounds made by a "roarer" and 

 therefore needs no further notice, except to state that this sound may be 

 made during an attack of severe "sore throat" and will pass away with 

 the disease that causes it. 



Thick Wind. This is another term which Is applied to a disease, 

 which is only a symptom. The great majority of horses called "thick 

 winded" belong either to the "roarers" or have the "heaves." Occa- 

 sionally a mare heavy with foal, or horses excessively fat are affected
