Abstract
The observations were made on brown people of whom 37 were men and 5 women; in addition, 8 [male] blacks were studied. The majority of the men were from Mico College and represented a homogeneous group so far as age, nutritive state and living conditions were concerned. These were for the most part between the ages of 19 and 22 yrs. The women were between the ages of 23 and 30 yrs., excepting one of 40 yrs. Some of the subjects were mildly infected with hook worm, otherwise in good health. In general, the observations were made under temp. conditions not unlike those obtained in many American laboratories in spring and summer. In addition to the well known factors of age, sex, height and weight, there is the possible influence of environmental temperature, humidity and the effect of dietetic habits, with special reference to the amount of protein consumed. The protein intake of these students was much lower than is commonly the case with American students. The physical activity was also much lower than for the average American student. With the [male] brown the general picture is that of a slightly depressed metabolism ([long dash]5%). The smaller groups of [female] browns and o blacks do not confirm these findings. Average deviation for these is but [long dash]2.0%.
