On the 28th of October, two days after our return to Kan- 
dy, at half-past 11 o’clock in the morning, I tried, for the last 
time, the temperature of these men, with the exception of two 
who were absent. They were in good health, though hardly 
recovered from the fatigue of a rapid harassing journey, in 
cool wet weather, through a country on the eve of breaking out 
in rebellion ; the temperature of the air at that time had sud- 
denly risen to 84° from 69°, which it was at 7 a. m.

Kandy, from its peculiar situation, so near the Equator., 
nearly in the middle of a large island, elevated as it is above 
the level of the sea, and surrounded by mountains, is subject 
to considerable vicissitudes of temperature in the course of the 
day, and consequently is a place well adapted for making ob- 
servations on the effects of these vicissitudes on animal heat. 
In fine weather, the temperature of the air at sun-rise is always 
below 70°, and I have seen it as low as 55° ; and in the after- 
noon, in such weather, it is always above 76°, and frequently 
as high as 83°. 
On the 18th of January 1818, a favourable day, I tried the 
temperature of an individual at different hours, and obtained 
the following results.

It may be proper to mention how the individual passed the 
day. He rose at 6 a. m. ; read till 9 a. m. ; breakfasted tem- 
perately at 10 ; was engaged in some chemical experiments from
