others of the same kind; and the excess of discharge may drop on 

 the hairs below and form similar brownish yellow crusts. The farcy 

 ulcers may retain their specific form for a considerable time — days 

 or even weeks — but eventually the discharge becomes purulent in char- 

 acter and assumes the appearance of healthy matter. The surface 

 of the gangrenous bottom of the ulcer is replaced by rosy granula- 

 tions, the ragged edges are beveled off, and the chancre is turned 

 into a simple ulcer which rapidly heals. 



The farcy buttons occur most frequently on the sides of the lips, 

 the sides of the neck, the lower part of the shoulders, the inside of 

 the thighs, or the outside of the legs, but may occur on any part of 

 the body. 



We have next an irritation of the lymphatic vessels in the neigh- 

 borhood of the chancres. Those become swollen and then indurated 

 and appear like great ridges underneath the skin; they are hot to 

 the touch and sensitive. The cords may remain for a considerable 

 time and then gradually disappear, or they may ulcerate like a farcy 

 bud itself, forming elongated, irregular, serpentine ulcers with a 

 characteristic, dirty, gray bottom and ragged edges, and pour out 

 a viscous, oily discharge like the chancres themselves. 



The essential symptoms of farcy are, as above described, the button, 

 the chancre, the cord, and the discharge. We have in addition to 

 these symptoms a certain number of accessory symptoms, which, 

 while not diagnostic in themselves, are of great service in aiding the 

 diagnosis in cases where the eruption takes place in small quantities, 

 and when the ulcers are not characteristic. 



Epistaxis, or bleeding from the nose without previous work or 

 other apparent cause, is one of the frequent concomitant symptoms 

 in glanders, and such a hemorrhage from the nostrils should always 

 be regarded with suspicion. The animal with farcy frequently de- 

 velops a cough, resembling much that which we find in heaves — a 

 short, dry, aborted, hacking cough, with little or no discharge from 

 the nostrils. With this we find an itregular movement of the flanks, 

 and on auscultation of the lungs we find sibilant or at times a few 

 mucous rales. Another common symptom is a sudden swelUng of one 

 of the hind legs; it is found suddenly swollen in the region of the 

 cannon, the enlargement extending below to the pastern and above as 

 high as the stifle. This swelling is hot and painful to the touch, and 

 renders the animal stiff and lame. On pressure with the finger the 

 swelling can be indented, but the pits so formed soon fill up again on 

 removal of the pressure. In severe cases we may have ulceration of 

 the skin, and serum pours out from the surface, resembling the oozing 

 which we have after a blister or in a case of grease. This swelling 

 is not to be confounded with the stocking in lymphatic horses or the 

 edema which we have in chronic heart or in kidney trouble, as
