386 THE MODERN HORSE DOCTOR. 



fact set forth every year in the comptes rendus of the Alfort 

 School. 



" It is no less certain that, in the greatest number of cases, 

 whenever a horse becomes glandered from over work, it falls 

 greatly off in condition before the disease makes its appearance 

 — a fact which accords with the great exhalation of carbonic 

 acid and water, the fatal consequences of the activity of the re- 

 spiratory and circulatory functions. 



" On the other hand, whenever glanders has declared itself, 

 the horse rapidly falls off — he becomes a dog-horse — and this 

 disappearance of his fat coincides with the augmented exhalation 

 of carbonic acid, which becomes remarkable at the period of 

 eruptive and acute glanders. 



" Another fact is, that the influence of excessive work may be 

 counteracted, and even rendered harmless, by a large reparative 

 alimentation. Demonstrative experience of this passed under 

 our eyes, on a very extensive scale too, on the occasion of the 

 construction of the fortifications of Paris. The horses worked 

 hard in draught became glandered or not, according as they be- 

 longed to masters who could afford to (and did) keep them well 

 or not. Most of the glandered horses were the property of un- 

 fortunate piece-workers, (idcherons,) knowing little of the man- 

 agement of horses, and too parsimonious of their feed ; while, 

 on the other hand, the disease spared such as were well fed by 

 wealthy contractors, undertaking the work on their own account. 



"XI. The laboring ox is not subject, on account of being 

 worked up, to any disease having the least analogy with glanders. 

 Not to notice his difference of organization, which is a principal 

 consideration in this question, I contend that the difference of 

 results from the same cause in the bullock and the horse is owing 

 to the modes of using them, to the constant slowness of pace of 

 the one, and the occasional and frequent rapidity of that of the 

 other. This difference may cease to exist whenever the ox is 

 forced into quick work, and especially should he be fat at the 

 time. In such condition, under the influence of hurried respira- 

 tion, oxidation of the combustible elements takes place with so 

 great rapidity that the exhalation of the carbonic acid product 

 cannot get vent with sufficient celerity, and the consequence is,
