Postscript to Dr. Davy’s Paper on the Temperature of Man. 
Received May 8, — Read May 16, 1850. 
The thermometer with which the preceding observations were made was broken 
immediately after my return to England, when travelling by railway, no special pre- 
caution having been taken in the packing of it, as by inclosing it in elastic horse-hair ; 
and in consequence I had not the means at once of making further trials on tempe- 
rature for the purpose of comparison. Recently, having had another thermometer 
constructed as delicate as that before used and divided with the same minuteness — 
each degree of Fahrenheit into ten parts — I have been enabled to continue the trials; 
as yet, however, only for one month, that of April, without interruption. They have 
been made thrice daily, at about the same hours as those recorded in my former 
paper. The results, under ordinary circumstances of health, exercise, &c., have ac- 
corded with those then obtained, the highest temperature having been found to be 
immediately on rising in the morning after the night’s rest, and the lowest at night, 
just before retiring to rest. This accordance will probably be received in proof that 
the difference of results in the West Indies and in England has been mainly owing 
to difference of climate and the habits of life connected therewith ; and apart from 
these, to no change in the individual, the subject of the trials. 
May 4, 1850.
