研究了美国白色和黑人士兵在湿热和干热条件下的生理反应。在湿热的条件下，40对身体脂肪、体重和身高相匹配的男性以每小时3.5英里的速度绕着一个路线走了一个小时。在炎热干燥的条件下，在8种不同的条件下研究了8对体脂、体重和身高相匹配的男性，这些条件包括服装、阳光、阴凉、行走和坐姿的组合。本系列实验结果表明：（1）在黑人和白人都穿衣服和步行的湿热条件下，黑人具有较高的生理耐受性。在炎热干燥的条件下，两组人都穿着衣服，走路或坐着，他们的耐受性大致相同。在炎热干燥的条件下，两组人都裸体暴露在阳光下，晒黑的白人有更高的耐受性。这些结果进一步表明，所发现的差异不是瞬时环境效应的函数，可能主要是遗传起源。结果进行了讨论，种族分类系统和人类形态属性的分布。
The physiological responses of American White and Negro soldiers were studied under hot-wet and hot-dry conditions. Under hot-wet conditions 40 pairs of men matched for body fat, weight and stature were walked around a course at 3 1/2 mph for one hour. Under hot-dry conditions 8 pairs of men also matched for body fat, weight and stature were studied under 8 different conditions which included combinations of clothing, sun, shade, walking and sitting. The results of this series of experiments indicated: (1) Under hot-wet conditions with both Negroes and Whites clothed and walking, the Negroes had a higher physiological tolerance. Under hot-dry conditions with both groups clothed, walking, or sitting they had about equal tolerance. Under hot-dry conditions with both groups nude and exposed to the sun, sun-tanned Whites had the higher tolerance. These results further suggested that the differences found were not a function of transient environmental effects and may be mostly genetic in origin. The results are discussed in relation to racial taxonomy systems and the distribution of human morphological attributes.
