444 DR. DAVY ON THE TEMPERATURE OF MAN WITHIN THE TROPICS. 
The additional observations — those made some hours after the exertion — are given 
as illustrating an important fact, viz. the rapid manner in which, when the body is 
free from disease, the functions on rest return to their ordinary state ; whilst, on the 
contrary, when disease is present, especially of an organic kind, even though latent 
in relation to the most obvious class of symptoms, indications of it may be obtained 
by attention to the temperature, pulse and respiration ; and often, as in instances 
of pulmonary disease, in a very remarkable and decided manner. 
8. On the Effect of Cool and IVell-ventilated Rooms, and of Close and Heated 
Rooms on the Temperature. 
As regards ventilation, and consequently coolness where there is a concourse of 
people, the cathedral church of Barbados, and Harrison’s school-room adjoining, in 
which lectures were given on the opening of the '■ Reid School of Practical Che- 
mistry,” may be mentioned as good and bad e.xamples. In illustration of the effects 
of each, 1 shall give a few observations on temperature, noted down when made, 
which was within about half an hour after quitting the church and the school, con- 
veyed in a carriage, attending in the one divine service, in the other a lecture. The 
temperature of the air marked, as usual, was that of my sitting-room, which was 
cooler by several degrees than the school-room, but less cool commonly than the 
church.

9. On the Effect of taking Food and Wine on the Temperature. 
The effect of a meal in moderation, whether the light one of breakfast or the fuller 
and heavier one of dinner, was to raise the temperature; and this also when wine 
was sparingly used at the latter, viz. to the extent of two or three glasses ; but when 
more freely drunk, as it commonly is in company, then often its influence on tempe- 
rature appeared to be depressing. I shall give a few instances in illustration : —
