FISTULA. 69 



disease is accompanied with fever, and hence it is called 

 lung fever. Fever in the feet is a common expression, 

 signifying sympathetic fever. -Indeed, it is a question 

 in my mind, whether fevers of all kinds are not to be at-

 sometimes they are superficial, or just under the skin. 

 However, notwithstanding, that we see them sometimes 

 so situated, it must be confessed that it is extremely rare. 

 The fistula, most frequent and difficult of cure, is always
