对七十九只黑猩猩、八十九只大猩猩和六十三只红毛猩猩的牙冠进行了测量。提供了每种猿的 48 个乳牙尺寸和指数以及 78 个恒牙列尺寸和指数的基本统计数据，包括平均值、头骨数量、标准差和平均值的标准误差。就恒牙而言，性别是分开的。由于磨损导致尺寸变化，因此需要进一步划分年龄组。即使这些细分产生的小样本，标准误差也很少大于平均值的 4%，因此获得的数字是对猿类牙齿变异性的可靠估计。这些数据为现有类人猿和化石类人猿牙齿之间的定量比较提供了基础。
Measurements have been taken of the crowns of the teeth of seventy-nine chimpanzees, eighty-nine gorillas and sixty-three orang-outangs. Basic statistical data, comprising the mean, the number of skulls, the standard deviation and the standard error of the mean, are presented for forty-eight dimensions and indices of the deciduous teeth and for seventy-eight of those of the permanent dentition of each type of ape. A separation between the sexes has been made in the case of the permanent teeth. Further separation has been made into age groups, where necessitated by changes in dimensions due to wear. Even with the small samples resulting from these subdivisions, the standard error is seldom greater than 4 % of the mean, and therefore the figures obtained are reliable estimates of the variability of the teeth of apes. The data provide a basis for quantitative comparisons between the teeth of existing and fossil anthropoids.
