Abstract
WE are greatly indebted to Dr. Yates and Mr. Healy for having brought to light, in the course of the computations they record above, the fact that our previous estimates1 of the standard deviations of the individual measurements of the teeth of the anthropoid apes are in error, and that our published figures need to be divided by √2. The mistake was due to a misunderstanding in the interpretation of the analysis of variance which was carried out to separate the component of variance that is due to differences between corresponding teeth in the same jaw and that due to differences between animals. The standard errors of the means of the dimensions are correct as published.
