 bilitating atmosphere. 



Nature does wonders in enabling every animal 

 to accommodate itself to the situation in which it is 

 placed, and the horse that lives in the stable, even 

 suffers less from it, than would scarcely be conceived 

 possible. But he does not, and cannot possess the 

 power and hardihood which he would acquire under 

 other circumstances. This air of the improperly 

 close and heated stable is still further contaminated 

 by the urine and dung, which rapidly ferment there, 

 and give out simulating and unwholesome vapors. 

 When a person first enters an ill -managed stable, 

 and especially early in the morning, he is annoyed 

 not only by the heat of the confined air, but by a 

 pungent smell, resembling hartshorn ; and can he 

 be surprised at the inflammation of the eyes, and the 

 chronic cough, and the disease of the lungs, by 

 which the animal who has been all night shut up in 

 this wretched atmosphere is often attacked ; or if 

 the glanders and farcy should occasionally break 

 out in such stables? It has been ascertained by 

 chemical experiment that the urine of the horse 

 contains an exceedingly large quantity of hartshoni, 

 and not only so, but that, influenced by the heat of a 

 crowded stable, and possibly by other decompositions 

 that are going forward at the same time, this am- 

 moniacal vapor begins to be rapidly given out, almost 

 immediately after the urine is voided. When dis- 

 ease begins to appear among the inhabitants of these
