breathe the expired air of giandered horses for an hour and a half a 

 day for seven days, by means of a tube of canvas, and was unable to 

 .produce the disease in any case. 



The stable attendants serve as one of the most common carriers of 

 the virus. Dried or fresh discharges are collected from the infected 

 animal in cleaning, harnessing, feeding, and by means of the hands, 

 clothing, the teeth of the currycomb, the sponge, the bridle, and 

 halter and are carried to other animals. 



An animal affected with chronic glanders in a latent form is moved 

 from one part of the stable to another, or works hitched with one 

 horse and then with another, and may be an active agent in the 

 provocation of the disease without the cause being recognized. 



Glanders is found frequently in the most insidious forms, and we 

 recognize that it can exist Avithout being apparent; that is, it may 

 affect a horSe for a long period without showing any symptoms that 

 will allow even the most experienced veterinarian to make a diagno- 

 sis. An old gray mare belonging to a tavern keeper was reserved for 

 family use with good care and light work for a period of eight years, 

 during which time other horses in the tavern stable were from time to 

 time affected with glanders without an apparent cause. The mare, 

 whose only trouble was an apparent attack of heaves, was sold to a 

 huckster, who placed her at hard work. Want of feed and overwork 

 and exposure rapidly developed a case of acute glanders, from which 

 the animal died, and at the autopsy were found the lesions of an acute 

 pneumonia of glanders grafted on chronic lesions, consisting of old 

 tubercles, which had undoubtedly existed for years. 



In a recent case under the care of the writer a coach horse was 

 examined for soundness and passed as sound by a prominent veteri- 

 narian, who a few months afterwards treated the horse for a skin erup- 

 tion from which it recovered. Twelve months afterwards it came into 

 the hands of the writer, hidebound, with a slight cough and a slight 

 eruption of the skin, which was attributed to clipping and the rubbing 

 of the harness, but which had nothing suspicious in its charactei\ 

 The horse was placed on tonics and put to regular light driving. In 

 six weeks it developed a bronchitis without having been specially 

 exposed, and in two days this trouble was followed by a lobular pneu- 

 monia and the breaking of an abscess in the right lung. Farcy buds 

 developed on the surface of the body and the animal died!^ The 

 autopsy showed the existence of a number of old tubercles in the 

 lungs which must have existed previous to purchase, more than a 

 year before. 



Public watering troughs and the feed boxes of boarding stables and 

 the tavern stables of market towns are among the most common recip- 

 ients for the virus of glanders, which is most dangerous in its fresh 

 state, but cases have been known to be caused by feeding animals in 

 the box or stall in which giandered animals had stocxl more than a
