accompanied with fever, and hence it is called lung fever. 

 Fever in the feet is a common expression, signifying sym- 

 pathetic fever. Indeed, it is a question in my mind, whether 

 fevers of all kinds are not to be attributed to some local or 

 general disturbance of some action or function of the body.

 sometimes they are superficial, or just under the skin. 

 However, although we see them sometimes so situated, 

 it must be confessed that the cases are extremely rare. 

 The fistula most frequent and difficult of cure is always 

 deep-seated and ia the vicinity of g, joint, as the poll and
