On the temperature of man within the tropics
In a former paper which was published in the Philosophical Transactions for 1845, the author gave the results of an inquiry on the temperature of man in England, as measured under the tongue by a thermometer made for the purpose, and using certain precautions necessary to ensure accuracy. An inquiry of the same kind and with the same instrument he has conducted in the West Indies, extending over a period of nearly three years' and a half. This is the subject of his present communication. For the sake of comparison, he has followed in it nearly the same order as in the former. The results are given in a tabular form, divided into sections, and are followed by an appendix in which are recorded the daily observations in monthly sequence, accompanied by observations on the pulse, respiration and atmospheric temperature. The following are the principal conclusions which seem to be warranted by the results:— 1. That the temperature of man within the tropics, on an average, is nearly 1° higher than in a temperate climate, such as that of England.
