tarly to a current of air ; thus riding against the 

 ti'ind will often produce it both in the horse and the 

 rider : tlie stable door opening against the horse's 

 flanks is a frequent cause also; in fact, any unusual ex- 

 posure will produce it. But what is less generally 

 known is, that this complaint is frequently taken from 

 the removing from a cold into a warm situation : thus 

 a horse removed from grass to a stable, commonly ex- 

 hibits symptoms of a cold. Any alteration of tempera- 

 ture, therefore, whether from heat to cold, or from 

 cold to heat, may produce it: — thia is an additional 

 argument against the keeping of stables so hot as they 

 usually are. There are some circumstances, independ- 

 ent of the known causes producing this affection, 

 with which we are not well acquainted: at some 

 times horses wilt resist the greatest variations of tem- 

 perature ; at others, the slightest change affects thema 

 It is peculiar that a horse, becoming habituated to 

 one stable, is hardly ever moved into another, even 

 though of the same apparent heat, without having a 

 cough. In many cases, colds and coughs seem de- 

 pendant on some particular effect the air in general 

 has on them ; in which cases they rage universally, 

 and put on an epidemic form. 



When a horse has been much exposed, and is sus- 

 pected of having caught a eold ; if, before its effects 

 have become apparent, w'arm clothing, a warm mash- 

 of malt, som.e sound ale, or in fact any thing that 

 proves a cordial to the constitution, is made use of, 

 the access of cold is prevented ; for a slight fever is 

 raised by this means in the constitution, that pre- 

 vents the foniiation of that which would have arisen 

 from the cold ; — the same takes place in ourselves^
