decreased in volume. Cough is present which is very 

 severe, though so far as may be possible suppressed. 



Treatment. — Apply a blister under the throat, over the 

 course of the windpipe, and along the chest. Clothe well, 

 and let the stable be rather warm than cold, though by no 

 means hot. Foment the nostrils with hot bran in a nose- 

 bag. Give the animal a drink composed of sulphuric ether 

 one ounce, laudanum one ounce, liquor ammonia acetatis 

 six ounces, solution of aloes four ounces, tincture of gen- 

 tian two ounces, and cold water one pint. Then three times 

 daily administer the adjoined, in the shape of drink, also 

 being careful to lower the horse's head that instant he 

 coughs : — 



Extract of belladonna one drachm. 



Liquor potassa; one ounce. 



Liquor ammimia acetatis six ounces. 



Tincture of cantiiarides a scruple. 



Give thrice a day till the appetite is lost. Then discontinue. 



Every night the drink composed of sulphuric ether and 

 laudanum and water may be administered, omitting, how- 

 ever, the liq. amm. acet. and the solution of aloes. Should 

 the cough be distressing, let the horse take a tar ball night 

 and morning. 



During the progress of such a complaint we need not

 passages should be the immediate consequences ; or other- 

 wise, that such an irritable state of them may remain after 

 the more active symptoms have ceased, as to give rise to 

 ruinous chronic affections. The inflammation may thus 

 leave roaring, w^heezing or whistling, as a sequel ; and thick 

 wind may result. 



CHRONIC DISEASES OF THE PULMONARY AERATING PASSAGES. 



ROARING. 



The artificial habits of life to which we subject the horse 

 occasion numerous morbid changes in his organs, yet in 

 none more than those connected with his respiration : and 

 not only do the grand masses of the lungs suffer, but the 

 very passages to them are altered in structure, and rendered 

 incapable of transmitting the air with its proper freedom. 

 The obstructing matter, on the principle of wind instru-
