DR. DAVY ON THE TEMPERATURE OF MAN WITHIN THE TROPICS. 
445 
It is deserving of remark, that whenever wine was used, except in great modera- 
tion, though never to the excess of an inebriating effect, on the following morning 
the temperature under the tongue was found to be more or less above the average, 
and the pulse commonly quicker than usual. It is also worthy of remark, that occa- 
sionally the effect at night was to increase the temperature of the body, and that in a 
marked manner ; but whether from some peculiar quality of the wine used, or from 
some deranged state of the system or other adventitious circumstance, I have not 
been able to determine. 
10. Of the Effect of Sea-sickness on the Temperature. 
During a voyage from Barbados to St. Christopher, and from thence to Barbados 
in May and June 1848, in a transport, stopping at some of the intermediate islands, 
an opportunity offered of making some observations on the effect of sea-sickness, 
from which I suffered more or less on the several days noticed in the subjoined Table. 
The degree of sickness, often amounting to vomiting, was such as to render rising 
disagreeable. Little food was taken on those days, excepting chicken broth witli 
some bread; no wine was drunk. The observations were made in the sitting posture 
in bed in a well-ventilated cabin.

It appears from these few observations, that under the influence of sea-sickness, 
the morning temperature was higher than ordinary and the pulse sotnewhat quicker; 
when the former was lowest, as on the 18th of May, then the vessel being in smooth 
water, there was scarcely any uneasiness experienced. Comparing the several obser- 
vations, perhaps the inference may be justifiable, that the tendency of sea-sickness, 
when not in its severest form, is of an equalizing kind in relation to the temperature, 
pulse and respiration, — a tendency no doubt promoted by the little variation to which 
the sea atmosphere is liable, especially within the tropics. On so obscure a subject, 
however, as sea-sickness, this remark is offered with some hesitation.
