specific discbarge is characteristic. The discharge accumulates on the 

 hair surrouudiug the ulcer and over its surface aud dries, forming 

 scabs which become thicker by successive deposits on the undersurface 

 until they fall off, to be replaced by 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 dis- 

 charge becomes purulent in character and assumes the appearance of 

 healthy matter. The surface of the gangrenous bottom of the ulcer is 

 replaced by rosy granulations, the ragged edges 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 at any part of the body. 



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

 hood of the chancres. These 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, form- 

 ing 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 the above; the button^ the chan- 

 cre, the cord, and the discharge. We have in addition to these symp- 

 toms a certain number of accessory symptoms, which, while not diag- 

 nostic 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 glan- 

 ders, and such a hemorrhage from the nostrils should always be regarded 

 with suspicion. The animal with farcy frequently develops 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 irregular movement of the flanks, and on auscultation of the 

 lungs we find sibilant or at times a few mucous rales. Another com- 

 mon symptom is a sudden swelling of one of the hind legs; it is suddenly 

 found swollen in the region of the cannon, the eulargemeut 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 stock- 

 ing in lymphatic horses, or the cedema which we have in chronic heart
