poison is still in the system, and will break out in a violent

Causes. — From what has already been said of this disease, 

 the reader will have expected to find the same causes operating 

 to produce it that are known to cause glanders — and such we 

 find to be the fact — surfeiting, filthy stabling, overwork, and 

 infection. Inoculation with the matter of glanders will produce 

 farcy, and with that of farcy will produce glanders. Hence, it 

 seems unavoidable to conclude that, if glanders is the result of 

 a particular poison, farcy is the consequence of the same poison 

 operating under modified circumstances. Why this virus 

 should, in the one case, first attack the mucous membrane lining 

 the air-passages, and in the other the lymphatic vessels and 

 glands, I know no satisfactory explanation. Yet the fact is not 

 at all inconsistent with well-known phenomena of disease in the 

 human family, as well as in the lower animals. Two persons 

 may be exposed to the miasm of a damp situation, where ani- 

 mal and vegetable substances are decaying, and the one be at- 

 tacked of typhoid fever, and the other of dysentery or fiux. 

 Two horses may be exposed, in the same team, to a hard drive, 

 rain, and cold, and the one take inflammation of the lungs, and 

 the other pleurisy. 



The older writers describe two varieties of farcy — button 

 farcy, the one we have described, and water farcy. But the 

 latter is now known to be of an entirely difiierent character from 

 true farcy, being a diffuse inflammation of the cellular membrane. 

 IS'o difiiculty need be experienced in distinguishing between the 

 two diseases. In the latter disease the swelling is in larger 

 lumps, which appear very suddenly, and is attended by puffy 

 swelling of the limbs, along the belly, etc. There are no knot- 

 ted cords, nor the small buds, to be found. Farcy may be dis- 

 tinguished from surfeit-lumps, which are large and irregular in 

 form, and of short continuance ; sometimes subsiding or going 

 away in a few liours, though oftener remaining some time. (See 

 Surfeit). To conclude my remarks on the distinguishing of
