Takahira notes that there are individual variations due to mode of life, occupation, and physical training. In women, whose basal metabolism averaged 9 per cent, below that of men, determinations during the menstrual period were avoided, but no rise in metabolism took place before the period (see p. 526). The basal metabolism of common laborers was higher than that of those in other occupations: Calories per Increase above Sq. M. Japanese Stand- per Hr. ard Per Cent. 30 common laborers (men) 40.23 +7.2 20 “ “ (women) 36.43 +7.2 Takahira concludes that the differences in metabolism between Japanese, Europeans, and Americans are slight and are such as may be observed in groups of any race. These conclusions are supported by the observations of Okada, Sakurai, and Kameda1 who find that 42 Japanese men show a basal metabolism which is 2 per cent, less than the Du Bois standards and that 11 women were 0.7 per cent, less than that standard. Eijkman2 took a Zuntz portable respiration apparatus to the tropics and in investigations made at Batavia in Java found that the 1 Okada, S., Sakurai, E., and Kameda, T.: Arch. Tnt.
