GLANDERS FARCY. 421 



large, and become adherent to the bone, feeling hard to the touch, 

 and almost like exostosis. Here the permanent character of the 

 discharge and the adherence of the glands to the bone are the 

 diagnostic signs from ozena. 



IN THE THIRD STAGE, the discharge increases rapidly, and be- 

 comes yellow and opaque in fact, it is pure pus. If the nose is 

 carefully examined, its lining membrane will be seen to present 

 one or more sores, with depressed centres and ragged edges, and 

 surrounded by small varicose vessels leading to thein from all 

 directions. In proportion to the extent of the local mischief, con- 

 stitutional disturbance is displayed. The appetite fails the horse 

 lose? flesh and spirits the coat is turned the wrong way the 

 skin is hidebound, and the legs fill slightly during the day, but go 

 down at night the nose is, at last, frightfully ulcerated, the sores' 

 spreading to the larynx ulcers break out on the body and the 

 horse finally dies, worn to a skeleton. 



When the diagnosis of the disease is confirmed, as it is undoubt- 

 edly highly contagious, both to other horses and to man himself, 

 the patient ought to be destroyed. By the use of green food, his 

 life may be prolonged for a time, and a certain amount of work 

 may be got out of him ; but the risk of contagion is too great to 

 be incurred, and no man who regards his own welfare, and that 

 of his neighbors, should keep a glandered horse. 



FAKCY. 



THIS DISEASE appears to depend upon the development of the 

 same poison as in glanders ; but the attempt at elimination is made 

 in the skin, instead of the mucous membrane lining the nose. A 

 horse inoculated with glanders may exhibit farcy, and vice versa; 

 so that the essence of the disease is the same, but its seat is a 

 different tissue. 



FARCY usually shows itself first by one or two small hard knots 

 in the skin, called " farcy buds." These soon soften, and contain 

 a small quantity of pus ; but as this is rapidly absorbed, the lym- 

 phatics which convey it into the circulation inflame; and at a 

 short distance another bud is formed, and then another, and 

 another. These buds are usually met with in the thin skin cover- 

 ing the inside of the thighs and arms, or the neck and lips. They 

 vary from the size of a shilling to that of a half-crown \ and as 

 they increase in numbers, the skin becomes oedematous. In pro- 

 cess of time, the general system suffers, as in glanders, and the 

 horse dies, a miserable, worn-out object. No treatment can be 

 relied on to cure the disease ; and as it is equally contagious with 

 glanders, every farcied horse ought at once to be destroyed. The 

 hard nature of the buds, and the thickened lymphatics extending 

 like cords between, clearly make known the nature of the disease.
