156 THE HORSE. 



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 inflammation of the lymphatic vessels in the neigh- 

 borhood 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, 

 forming elongated, irregular, serpentine ulcers with a characteristic, dirty, 

 gray bottom and ragged edges, and pour out a viscious 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 re- 

 garded 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 auscul- 

 tation of the lungs we find sibilant or at times a few mucous rales. An- 

 other common symptom is a sudden swelling of one of the hind legs; it 

 is suddenly found 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 oedema which we have in chronic
