82 THE ARMY HORSE. 



The enlargement of the lympathie ghmds situated in the 

 space betAveen the lower jaw is another important symptom. 

 In the beginning the gland is a little sensitive, slightly doughy, 

 and adheres to the base of the tongue or to the lower maxillse; 

 in some subjects it adheres to the skin. In exceptional cases 

 the enlargement of the gland is absent. 



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

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



There is frequently difficulty in breathing, and the patient 

 becomes rapidly fatigued. 



Farcy. 



(Plate XV.) 



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

 tlie 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. 



SyTYiptoms. — Acute glanders is rare in the liorse (10 per 

 cent), except in transit and in tropical climates. It is, on the 

 contrary, the ordinary form in the mule. Sometimes it is 

 primary ; in other instances it follows the chronic form, where 

 the vitality of the animal has been lessened by other acute 

 affections. 



The disease produces an ulcerous destruction of the respira- 

 tory mucous membrane, and also involves the skin, lungs, and 

 other organs. 



It begins with a chill, followed by intense fever, which 

 reaches 107° F. A sticky, yellowish, irritating, bloody nasal 

 discharge appears. The nasal mucous membrane is overrun 

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

 may perforate the septum nasi. The respiration is rattling, 

 wheezing, and moaning due to»contraction of the larynx; to 

 these sj'mptoms are often added those of farcy. "We may find 

 diarrhea. The patient is extremely weak and emaciation pro- 

 gresses rapidly. 



In general, acute glanders runs a rapid course; its usual 

 termination is death. This ordinarily takes place within from 

 three to fourteen days.
