Fetal and infantile development of weight and height are studied in relation to period of gestation and weight of placenta. The body weight at birth was selected as a measure of fetal development, whereas the development attained at the age of 6 years served as a measure of intantile growth. Weight and height at birth increase only slightly with increasing duration of pregnancy, whereas there is no cchange in the weight at birth/placental weight ratio. The weight at birth increases with increasing weight of placenta. The quotient weight at birth/weight of placenta increases with a deviation of the weight from the average constitution (represented in this study by the relation between height and weight). Deviations from the mean weight, the mean body height and the mean constitution at birth are still noticeable even when the child has reached the age of six, although on the whole there is evidence of a tendency towards levelling-out. The weight at birth correlates more closely with the placental weight than with the body weight at the age of 6 years. The shorter the period of gestation, the higher the body weight at the age of six. This connection is explained by the action of the feeding centre which participates in both inducing parturition and in developing the body weight. There is no connection between placental weight and body weight at the age of six.
研究了胎儿和婴儿体重与身高的发育情况，并将其与妊娠期和胎盘重量相关联。出生时的体重被选作胎儿发育的一个衡量指标，而6岁时所达到的发育水平则作为婴儿生长的一个衡量指标。出生时的体重和身高仅随着孕期的延长而略有增加，而出生体重/胎盘重量的比值则没有变化。出生体重随着胎盘重量的增加而增加。出生体重/胎盘重量的商随着体重偏离平均体质（本研究中由身高与体重的关系表示）而增加。即使孩子到了6岁，出生时平均体重、平均身高和平均体质的偏差仍然很明显，尽管总体上有趋于平稳的趋势。出生体重与胎盘重量的相关性比与6岁时的体重更为密切。妊娠期越短，6岁时的体重越高。这种联系是由参与诱导分娩和体重发育的摄食中枢的作用来解释的。胎盘重量与6岁时的体重之间没有联系。
