THE HOKSE AND ITS DISEASES. 113 



Notwithstanding the clearness of the cause, the cure is 

 not so evident. If a harsh hollow cough is accompanied 

 by a staring coat, and the appearance of worms, a few 

 worm balls may expel these parasites, and remove the 

 irritation of the intestinal canal. If it proceeds from 

 irritability of the air passages, which will be discovered 

 by the horse coughing after drinking, or when he fii'st 

 goes out of the stable in the morning, or by his occasion- 

 ally snorting out thick mucus from the nose, medicines 

 may be given, and sometimes with advantage, to diminish 

 irritation generally. A small powder given in a bran 

 mash composed as follows, every night for 9 days, will 

 have a beneficial effect : — 



l^itre 3 drachms. 



Tartar Emetic 1 



>) 



and a cough ball every morning, made with the following : 



Opi, Crude 1 drachm. 



Garlic 2 ,, 



Gum 2 „ 



Tartar Emetic 1 ,, 



Made up with Tar, 



The above ball to be given the first thing in the 

 morning, a bran mash one hour afterwards, half an hour 

 gentle trotting, exercise at twelve o'clock, weather 

 permitting ; hay, five pounds per day ; walking exercise 

 morning and evening, for half an hour at the time, and 

 the animal to be well clothed ; also, take four quarts of 

 blood away, and blister the glands ; when chronic cough 

 occurs after eating, the seat of the disease is evidently 

 in the substance of the lungs. The stomach distended 

 with food presses upon the diaphragm, and the diaphragm 

 upon the lungs, and the lungs already labouring under 

 some congestion, are less capable of transmitting the 

 ail'; in the violent effort to discharge their functions, 

 irritation is produced, and the act of coughing is the 

 consequence of that irritation.
