appear like great ridges underneatb the skin; thej are hot to the touch 

 and sensitive. The cords may remain for a considerable time and then 

 graduall}' disappear, or the}^ may ulcerate like a farcy bud itself, form- 

 inj>- elongated, irregular, serpentine ulcers with a characteristic, dirty, 

 gray bottom and ragged edges, and pour out a viscous, oih' discharge 

 like the chancres themselves. 



The essential s^nnptoms 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 s3^mptom8, 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 glan- 

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

 regarded with suspicion. The animal with farc}^ frequently develops 

 a cough, resembling much that which w^e find in heaves — a short, drj^, 

 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 w^e find sibilant or at times a few mucous rales. 

 Another common symptom is a sudden swelling 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 scrum pours out from the surface, resembling the oozing w^hich we 

 have after a blister or in a case of grease. This swelling is not to be 

 confounded with the stocking in Ij'mphatic horses or the edema which 

 we have in chroni<; heart or in kidne}" trouble, as in the last the sw^elling 

 is cool and not painful and the pitting on pressure remains for some 

 time after the latter is withdrawn. It is not to be confounded with 

 greasy heels. In these the disease commences in the neighborhood of 

 the pastern and gradually extends up the leg, rarelv passing beyond 

 the neighborhood of the hock. The swollen leg in glanders almost 

 invariably swells for the entire length in a single night or within a 

 ver}'^ short period. When greasy heels are complicated b}' lymphan- 

 gitis we have a condition very much resembling that of farcy. The 

 swelled leg in farcy is frequently followed by an outbreak of farcy 

 buttons and ulcers over its surface. In the entire horse the testicles 

 are frcquentl}'^ swollen and hot and sensitive to the touch, but they have 

 no tendency to suppuration. The acute inflammation is rapidl}^ fol- 

 lowed by the specific induration, which corresponds to the local lesions 

 in other parts of the body.
