302 Dr Davy on the Temperature of Man, 
On the 4th of April, in Lat. S. 23° 44', at between 12 o’clock 
and 1 in the afternoon, when the weather was very fine, a 
gentle breeze blowing, and the temperature of the air 80°, I re- 
peated my observations on the preceding gentlemen, and on 
four more, and on a little girl and a boy. The circumstances 
were favourable, much the same as those already described, 
and the individuals not unusually warm, though our sensation 
of heat was rather more than was agreeable.

Lastly, on the 5th of May, in Lat. S. 35° 22', after having 
been three weeks between this latitude and that of 30°, the 
weather damp and cool, I repeated my observations on a few 
of the same gentlemen as before, and at noon, when the tem- 
perature of the air was 60°, and when we felt cool, almost 
cold.

I have had an opportunity of observing the effect of the sud- 
den change of atmospheric temperature on the heat of man, in 
descending from Kandy to Trincomalie. 
The town of Kandy, the capital of the interior of Ceylon, is 
situated in Lat. N. 7° 17', and is elevated about 1500 feet above 
the level of the sea*. Trincomalie, celebrated for its harbour, 
the first in the east, and one of the best in the world, is situa- 
ted in Lat. 8° 34'. Kandy is surrounded by hills and moun- 
* This elevation I have ascertained by means of the barometer. For the 
exact latitude of Kandy I am indebted to G. Lusignan, Esq.
