8 Medical Topography of the 



in several instances, one of which, a child, died after 

 many weeks ; another recovered, after losing a con- 

 siderable piece of the jaw-bone, with three of the 

 double teeth in it. Neither of these patients had 

 taken calomel, but considerable quantities of bark 

 and wine. 



We have a fever in this country, which has got the 

 name of Lake- Fever. This is the fever which is said 

 to be not unlike the Yellow-Fever. It never attacks 

 us till late in the summer, and the first months of au- 

 tumn. A frost sufficient to stiffen the mud, or freeze 

 water so that it can be perceived, puts an end to any 

 new cases. It begins with slight chills, pains of the 

 back, loins, and head. The symptoms do not vary 

 from those of the ague and fever, except in the dura- 

 tion of the paroxysms, which have regularly an exa- 

 cerbation once in twenty-four hours, and commonly 

 in the latter part of the day. These fevers have no 

 regular duration or change, but frequently end in re- 

 gular fits of the ague and fever, and sometimes go off 

 as the typhus. It often happens, that those who 

 have been afflicted with this fever remain debilitated, 

 and subject to slight returns, for two or three years, 

 with oedematous swelling of the feet, hands, and face, 

 a pale yellowness of the skin, flatulency of the stomach, 

 and, in a few instances, a vomiting of yellow bile, 

 once in every few weeks. I have never seen any 

 thing which resembled the black-vomit y as described 

 in the Yellow- Fever.
