THICK WIND. — BROKEN WIND. 269 



consideration are of a numerous character, some of which I 

 shall enumerate, in order to shew how their ill effects may 

 as far as practicable be counteracted. 



Amongst the principal of these causes, a thick, close 

 atmosphere ; distention of the stomach and bowels, either from 

 feeding too abundantly, or from the animal drinking too much 

 water; also the presence of an abnormal amoimt of gases 

 within the intestinal canal ; also taking the horse to severe 

 work immediately after he has been heartily fed, with perhaps 

 bulky food, are amongst the most common. The two last, 

 indeed, regarded in combination, are causes which on nume- 

 rous occasions give rise to the immediate death of the 

 animal. 



Improper articles of diet constitute another class, the prin- 

 cipal of which are — mow-burnt hay, fusty oats, soft beans, and 

 hard water, 



FoEMS OF Disease which mat be mistaken for 

 Thick Wind and Broken "Wind. — The principal of these, 

 and which indeed is not unfrequently mistaken for Thick 

 "Wind, is a peculiar state of the respiratory organs often 

 present within their mucous tissues, and which, in the gene- 

 rality of cases, is to be clearly traced to a severe attack of 

 Epizootic Catarrh. 



The state in question is characterised by a general debility, 

 manifested not only in the action of the animal, but in the 

 breathing also. The symptoms in many respects are closely 

 similar to those of Thick Wind. The animal blows heavily, 

 especially when travelling up a hill, and occasionally looks round 

 to his sides ; utters perhaps a faint grunt, or an occasional 

 cough, accompanied with a slight wheezing sound during the 

 act of inspiration.
