TATHOLOGY. <?7 



That these vefsels equally extend to the sur- 

 face, is evident ; for if turpentine he applied tcr 

 the skin, it very soon pafses to the kidneys, and is 

 discovered in the urine hy its smell ; and a blister 

 of cantharides has frequently been known to affect 

 the urinary pafsages; 



When these vefsels are gently stimulated, they 

 ■will remove cartilage, bone, &c. as in spavin and 

 splints ; and obstinate diseases of the eyes often 

 owe their cure to the action of these vefsels alone. 



From what has been said, we may conclude, 

 that the causes of farcy are, principally, putrid 

 matter coming in contact with the skin, altering 

 the action of these vefsels, and causing inflamma- 

 tion, &c. Change of temperature, by proaucing 

 great debility, may be another cause. Want of 

 exercise and cleanlinefs may have a tendency to 

 produce farcy. It has been known to take place 

 after the cure of obstinate grease*, and always 

 from the absorption of the matter of glanders. In 

 short, any cause producing long-continued debility f 

 may produce farcy. 



* Or by absorption of matter from old ulcers on th«f 

 fettack joints.
