62 NAVIX ox THE HORSE. 



certain undertakings, is one of the most frequent causes of 

 glanders, acute and chronic; but principally of acute. No 

 discussion, I should imagine, Avill aidse on this point, it being 

 an acknowledged fact, set forth every year in the Comptes 

 Rendus (or Annual Publication) of the Atfort school. 



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

 whenever a horse becomes glandered from overwork, it falls 

 greatly off in condition before the disease makes its appear- 

 ance — a fact which accords with the great exhalation of car- 

 bonic acid and water, the fatal consequences of the activity 

 of the respiratory and circulatory functions. 



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

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

 disappearance of his fat corresponds with the augmented ex- 

 halation 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 re- 

 parative alimentation. Demonstrative experience of this 

 passed under our own eyes, on a very extensive scale, too, on 

 the occasion of the construction of the fortifications of Pai*is. 

 The horses worked hard in draught became glandered, or not, 

 according as they belonged to masters who- could afford to 

 (and did) keep them well, or not. Most of the glandered 

 horses were the property of unfortunate piece-workers, know- 

 ing little of the management 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 to gland- 

 ers. N'ot 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 con-"
