Temperature of different parts oj the Body. 51 



Observations on my own temperature were in accordance 

 with the preceding. I may mention a few made on the follow- 

 ing day, at different times, when in my cabin, where the teni- 

 perature of the air was uniformily 80°. 



These observations, and many more which I made during 

 the voyage, and since landing in Barbadoes, clearly shew that 

 the temperature of the body rises with the temperature of the 

 air, and that on sudden transition from a mild or cool climate 

 to a hot climate, there is a tendency to a state approaching to 

 a feverish state, marked not only by increase of temperature, 

 but also by accelerated action of the heart and quickened respi- 

 ration, especially on making bodily exertion. 



Such effects obviously suggests to the newly arrived in a 

 tropical climate great temperance in all things ; the using less 

 wine and animal food than they had been accustomed to in a 

 cooler atmosphere ; dressing coolly, and avoiding as much as 

 possible, for a time, all fatiguing exercise and exposure to the 

 sun. Unfortunately, such care is seldom observed, and many 

 have to regret the neglect of it ; indeed, on landing, it is often 

 difficult to observe the precautions which health requires, 

 there being commonly duties to be performed demanding im- 

 mediate exertion and exposure ; not to mention the tempta- 

 tions to do too much, arising out of curiosity on visiting a 

 country new to one. 



4. Of the Temperature of different parts of the Body on entering 

 a Warm Climate. 

 Common observation shews, that on entering a warm cli- 

 mate, the extremities especially become warm ; coldness of the 

 hands and feet is no longer experienced, but rather an unplea- 

 sant sensation of heat in them, with a disposition generally in
