CHAP. II.] CONSTRUCTION AND USES OF NERVES. 97

 eliminated with the dung. At least, such is the na- 

 tural course in health ; a change takes place when 

 these organs do not perform their functions aright, 

 and we can perceive this misfortune in the dung, 

 when the liver is at fault, particularly in the yellows. 

 The importance of stimulating the lymphatics in all 

 disorders of the outer surface, as mange, surfeit, 

 farcy, &c. must be evident : as it is> also, in cases of 

 tumors, as poll-evil, fistula, and quittor.
