and the one readily participates in the irritation produ- 

 ced in the other. 



Jf a hard 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 first goes out of 

 the stable in the morning, or by his occasionally snort- 

 ing out thick njucus from the nose, medicines may be 

 given, and sometimes with advantage, to diminish irri- 

 tation generally. Small doses of digitalis, emetic la; (ar, 

 and nitre, administered every night, frequently have a 

 beneficial effect, espt cially when mixed with tar, which 

 seems to have a powerful influence in allaying the irri- 

 tation. 



Feeding has much influence on this complaint. Too 

 much dry meat, and especially chalf, increases it. 



Wheii chronic cough chiefly occurs after eating, the 

 seat of the disease is evidently in the substance of the 

 lungs. 



The two most frequent consequences of severe chest 

 afleclions in the horse are recognised under the terms 

 thick ivlnd and broken loiiid. The breathing is hur- 

 ried in both, and the horse is generally much distressed 

 when put upon his speed ; but it is simply quick bieath- 

 ing in the first, witli a peculiar sound like half-rooiing 

 — the inspirations and expirations being rapid, forcible, 

 but equal.

 the cough becomes chronic, leads on to thick-wind, and 

 then there is but a step to broken-wind. 



Is there any cure for broken-wind ? None ! ]No me-

If, however, we cannot cure, we may in some degree 

 palliate broken-wind ; and, first of all, we must attend
