Growth of body height and weight and skeletal maturation are discussed, based on 49 male and 61 female Hottentot children aged 3 to 17 years from Warmbad, Namibia (South West Africa) and 124 boys and 113 girls aged 1 to 21 years of related populations, the Rehoboth Basters of Namibia and Cape Coloreds from Cape Town, South Africa. The related populations are taller and heavier than the Hottentots, and have almost the same body height as American blacks and whites at least after the age of 18 years. In the Hottentots and Rehoboth Basters, the mean TW2 skeletal age is always less than the British standard by one or two years in both sexes. In general, the Rehoboth Basters have a skeletal age that is intermediate between Hottentot and British children. In both Hottentots and Rehoboth Basters, the increase in body height shows a linear relation to the skeletal age, and the regression curves are almost parallel in both sexes. The differences in body height and weight between the Hottentots and Rehoboth Basters become greater after the skeletal ages of 15 years for boys and 13 years for girls.
基于来自纳米比亚（西南非洲）瓦尔姆巴德的49名3至17岁的霍屯督男孩和61名同龄女孩，以及纳米比亚的雷霍博斯混血儿和南非开普敦的开普有色人种的124名1至21岁男孩和113名同龄女孩，对身高、体重增长以及骨骼成熟情况进行了讨论。相关群体比霍屯督人更高更重，至少在18岁以后，他们的身高与美国黑人和白人几乎相同。在霍屯督人和雷霍博斯混血儿中，两性的TW2骨骼平均年龄总是比英国标准低一到两年。一般来说，雷霍博斯混血儿的骨骼年龄介于霍屯督儿童和英国儿童之间。在霍屯督人和雷霍博斯混血儿中，身高增长与骨骼年龄呈线性关系，两性的回归曲线几乎平行。对于男孩，骨骼年龄在15岁以后，对于女孩，骨骼年龄在13岁以后，霍屯督人和雷霍博斯混血儿在身高和体重上的差异变得更大。
