5. Of the Early Morning Temperature of the Body withiti the 



Tropics. 

 According to the observations which I have made in Eng- 

 land, the temperature of the body, as measured by a ther-

 midnight, and highest on rising, after the rest of the night : 

 the average difference was 0.82. The limited observations 

 which I have as yet made within the tropics, lead me to infer 

 that the early morning temperature, just after waking and 

 quitting bed, is lower than the night temperature before retir- 

 ing to rest, and decidedly lower than the day temperature. 

 The following are a few of the observations which I have 

 hitherto made, leading to this conclusion. Of these some were 

 made at sea — those preceding the 7th of July ; the rest after 

 landing : —
