some subjects it is adherent to the skin. In exceptional cases 

 the enlargement of the gland is wanting. 



The general health of the animal suffers as the affection pro- 

 gresses; emaciation appears; the hair becomes dull and bristly. 



We frequently observe the symptoms of asthma and the patient 

 becomes rapidly fatigued. 



Cough is frequently present. 



Farcy. 



Farcy is naore rare in the chronic than in the acute form of the 

 disease: its favorite regions are the inner side of the extremities, 

 shoulders, neck, chest, and abdomen. 



The pimples and tumors vary from the size of a pea to that of 

 a walnut, or larger; they suppurate and discharge a yellow, sticky 

 liquid of bad aspect. They rarely heal, and if they do a jagged 

 scar remains. 



Acute glanders. 



Symptoms. — Acute glanders is rare in the horse (10 per cent). 

 It is, on the contrary, the ordinary form in the ass and mule. 

 Sometimes it appears from the beginning, in other instances 

 it follows the chronic form, where the vitality of the animal is 

 lessened by other acute affections. 



It runs a rapid courss, producing an ulcerous destruction of 

 the respiratory mucous membrane, and also involves the skin, 

 lungs, and other organs. 



The disease begins with a chill, followed by intense fever, which 

 reaches 107'' F. We observe a sticky, yellowish, irritating, bloody 

 nasal discharge. The nasal mucous membrane is overrun with 

 pimples and ulcers, which rapidly join one another; they may 

 p3rforate the septum nasi. The respiration is rattling, wheezing, 

 and moaning (laryngeal contraction); to these symptoms are 

 often added those of farcy. We may find diarrhea. The patient 

 is extremely weak and emaciation progresses rapidly. 



In general, acute glanders has a rapid course; its usual termi- 

 nation is in death. This ordinarily takes place within from three 

 to fourteen days. 



In the horse there is no disease of which an exact diagnosis is 

 so important as that of glanders. Other horses and mules are 

 not alone liable to contract the disease from affected animals; it 

 can be communicated to man as well.
