on the subject throwing no light on it, I shall abstain from 

 dwelling upon that part of its history. 



Cause. — Ill-ventilated and not properly drained stables, 

 we fear, are too frequently the remote cause of glanders. 

 There the ammonia from -the urine fills the whole atmo- 

 sphere ; this being constantly inhaled, ultimately produces 

 a poisonous effect upon the lungs, in consequence of an 

 undue quantity of oxygen being breathed. Besides, the con- 

 stant irritation which it must naturally produce upon that 

 delicate portion of the mucous membrane, which is the organ 

 of smell, it induces the formation of those tubercles which, 

 once formed, can never be eradicated. 



We find that glanders almost invariably breaks out in ill- 

 aired stables, and which are besides kept too hot. Fracture 

 of the nasal bone has also been known to produce this 

 malady ; as well as a long-continued and inveterate catarrh, 

 with a constant and irritating discharge from the nostrils, 

 may assume the form of glanders. We find that in the lofty, 

 well-aired stables of gentlemen this disease is comparatively 

 little known, and when it does show itself in such, it has in 

 all probability been introduced by some addition to his 

 stud, of one or more horses previously affected. In such a 

 case, all the other animals in the stable may catch the 

 malady, as glanders is known to be highly contagious. In 

 many of the crowded, ill-aired stables of London and other 

 large cities, this disease is but too often an inmate, and 

 frequently great havoc is made among the horses in conse- 

 quence. Persons who are in the daily habit of riding to 

 town, should bespeak a stall expressly for themselves in a 

 livery- stable, because, by introducing a diseased horse, the 

 infection may be caught by their horses, in consequence of 

 any slight wound about the muzzle coming in contact with 

 the crib, on which the mucus of the glandered animal has
