the animal dies asphyxiated or charbonneux. In this case, a new 

 principle, a ferment, becomes generated in the blood under the 

 influence of extreme oxidation. 



" XII. I am not to be supposed to admit that in every case 

 glanders is the result of extreme oxidation. I reserve this inter-

FARCY. 



Authorities define farcy to be a disease of the lymphatic ves- 

 sels, making its appearance in the form of circular swellings, 

 termed farcy buds, which terminate in a discharge and ulcer- 

 ation. 



Symptoms. — The horse usually exhibits some symptoms of a 

 deranged condition ; sometimes, however, scarcely noticeable, at 

 others very apparent. The horse is not in his usual spirits, 

 appears dull, and does not partake of food with his accustomed 

 relish. Some horses will have febrile symptoms, pulse quicker 

 than natural, mouth hot, urine high-colored, &c. ; others are 

 suddenly attacked with a swollen leg. Horses often become sud- 

 denly lame in one of the hind extremities. Mr. Percivall re-

 the cause and seat of lameness, no suspicion having existed, at 

 the time, that farcy was present in the animal's system. It may 

 so happen, however, that none of these preliminary symptoms 

 are observed or observable ; that, on the contrary, farcy at once 

 develops in an attack on some locality — most probably one hind 

 limb. Indeed, so sudden, sharp, and severe are attacks of farcy 

 in some instances, that in the course of one night the horse's 

 limb will be swollen to a frightful size, so as to incapacitate him 

 almost from turning in his stall and walking out of the stable. 



" Ordinarily the development of farcy plainly accounts for the 

 halting or lameness ; now and then, however, the lameness ap- 

 pears without any ostensible cause. 



" Viewing the affected limb from behind, we perceive a fulness 

 on the inside of the thigh, along the course of the femoral vein ;
