IV. Conclusions and General Remarks. 
That the temperature of man increases in passing from a cold 
or even temperate climate into one that is warm, — that the tem- 
perature of the inhabitants of warm climates is permanently 
higher than the temperature of those of mild, — and that the 
temperature of different races of mankind, ccderis paribus , is 
very much alike, — are conclusions which the preceding obser- 
vations on man seem to warrant. 
The first conclusion, I am aware, is not novel ; but I do not 
know that it was ever drawn before, excepting from very scan- 
ty data. 
The second conclusion, though conformable with the first, is, 
I believe, new ; indeed it is contrary to a received opinion, that 
the temperature of man in warm climates is actually lower than 
in cold. The opinion alluded to, I conceive, arose partly from 
hypothetical views of the subject ; and if I recollect rightly, it has 
been supported only by two or three observations recorded by 
Dr Chalmers in his History of South Carolina, which were 
made at a time when thermometrical experiments were not verv 
common, and when the standard temperature of man was rated 
much too low. Farther refutation of this opinion is perhaps 
unnecessary. The experiments I have made, with all the care 
in my power, are so numerous, and their results are so con- 
sistent, that, if I do not deceive myself, they put the question 
beyond the shadow of doubt, and fix as a fact, that, if the stand- 
ard temperature of man, in a temperate climate, be about 98°, 
(which I believe is the nearest approximation to the truth), in 
a hot climate it will be higher, varying with atmospheric varia- 
tion from 98J° to 101°. 
The third conclusion I believe to be perfectly accurate ; I 
say believe , because it is difficult, if not impossible, to collect 
more than presumptive evidence on the subject. However, 
may not the evidence be considered sufficiently satisfactory, 
since the variation of the temperature of the different races I 
tried did not exceed, in degree, what may be witnessed amongst 
different individuals of a ship’s company, all of one nation, or
