IV.—Observations on the Normal Temperature of the Monkey and its Diurnal Variation, and on the Effect of Changes in the Daily Routine on this Variation

Abstract

The observations recorded in the following pages were begun upwards of four years ago. In the course of an investigation into the anatomy and physiology of the central nervous system of the monkey, it was deemed necessary, amongst other things, to note whether the lesions established had influenced the temperature of the affected limbs. On consulting the chapter on “Animal Heat” by Pembrey in Schäfer's Text-booh of Physiology, and Richet's article “Chaleur,” in the Dictionnaire de Physiologie to find what the normal temperature of the monkey was, it was discovered that very few observations on the temperature of this animal had been made. Considering the high position which the monkey occupies in the animal scale, it seemed to us that this was an omission which we might with advantage do something to remedy; we decided therefore to avail ourselves of the material at our disposal, and to record the temperature of such healthy monkeys as should come into the laboratory from time to time.
