“…In addition to such differences in selection, variations in circumstances of measurement and in the age-and-sex structures of the population samples make statistical comparisons between previous studies and our own unwarrantable. Nevertheless it is apparent from the studies most closely resembling ours-those of Whiting (1915) in England, Ivy (1945) in America, Renbourn and Bonsall (1946) in India, and Cullumbine (1949) in Ceylon ( ings. This conclusion is confirmed by our own observations in Melbourne (Table III), in which it was found that the mean oral temperatures in hot weather were similar to those of the Islanders.…”

“…Several other features of the Islanders' temperatures suggest that this is so. The frequency distributions of the temperatures look normal, as do those of the populations studied by Whiting (1915), by Renbourn and Bonsall (1946), and by Ivy (1945). A high incidence of fevers would cause positive skewness or a bimodal distribution.…”

“…This conclusion is confirmed by our own observations in Melbourne (Table III), in which it was found that the mean oral temperatures in hot weather were similar to those of the Islanders. The occurrence of higher oral temperatures in tropical than in temperate conditions is evident even in population samples selected, like those of Renbourn and Bonsall (1946) and of Cullumbine (1949), as being free from disease. In the light of these findings it is reasonable to regard the mean temperatures of the Fijians and Gilbertese as natural to their climatic environment rather than as reflecting a high incidence of febrile illnesses.…”

“…Several studies indicated that a smaller increment of the T re in a warm ambient temperature has often been observed in HA people (Gisolfi and Robinson, 1969;Gisolfi, 1973;Henane and Bittel, 1975;Nielsen et al, 1993). This higher core temperature accompanying HA has often been reported in the literature (Davy, 1850;Sundstroem, 1927;Mason, 1940;Renbourn, 1946;Ladell, 1964;Cisse et al, 1991). For example, people living in a tropical climate have been shown to have a higher oral temperature in summer when compared to winter (Driver, 1958).…”

The effect of low-intensity exercise in the heat on thermoregulation and certain biochemical changes in temperate and tropical subjects under poorly and well-hydrated states was examined. Two VO 2max matched groups of subjects consisting of 8 Japanese (JS) and 8 Malaysians (MS) participated in this study under two conditions: poorlyhydrated (no water was given) and well-hydrated (3 mL · Kg Ϫ1 body weight of water was provided at onset of exercise, and the 15th, 35th and 55th min of exercise). The experimental room in both countries was adjusted to a constant level (Ta: 31.6Ϯ0.03°C, rh: 72.3Ϯ0.13%). Subjects spent an initial 10 min rest, 60 min of cycling at 40% VO 2max and then 40 min recovery in the experimental room. Rectal temperatures (T re ) skin temperatures (T sk ), heart rate (HR), heat-activated sweat glands density (HASG), local sweat rate (M sw-back ) and percent dehydration were recorded during the test. Blood samples were analysed for plasma glucose and lactate levels.The extent of dehydration was significantly higher in the combined groups of JS (1.43Ϯ0.08%) compared to MS (1.15Ϯ0.05%). During exercise M sw-back was significantly higher in JS compared to MS in the well-hydrated condition. The HASG was significantly more in JS compared to MS at rest and recovery. T re was higher in MS during the test. T sk was significantly higher starting at the 5th min of exercise until the end of the recovery period in MS compared to JS.In conclusion, tropical natives have lower M sw-back associated with higher T sk and T re during the rest, exercise and recovery periods. However, temperate natives have higher M sw-back and lower T sk and T re during experiments in a hot environment. This phenomenon occurs in both poorly-hydrated and wellhydrated states with low intensity exercise. The differences in M sw-back , T sk and T re are probably due to a setting of the core temperature at a higher level and enhancement of dry heat loss, which occurred during passive heat exposure.

“…early stages of disease. Renbourn and Bonsall (1946) have brought this question up to date. Sundstrcem (1927), Radsma (1938), andMason (1940) noted that the mean temperature of tropical white residents was above the usual normal.…”

The time is opportune for a re-discussion of the important problem of climate and human survival. During the recent war it was made plamn to us that campaigning might take place in all parts of the globe and in climates which were as varied as they were extreme. It was not merely' a question of carrying on a desultory or sedentary existence in *inauspicious environments, but of maintaining the highest possible. vigilance and efficiency while engaged in heavy manual work. We are reminded of the statement of Burot and Legrand, that " in the tropics the soldier is always in campaign; if not against the enemy, at least against the climate." And again of the Roman axiom, " In the land of the enemy, beware of the country, the water, and the time of the day."
