Abstract
EXPERIENCE has shown that it is often dangerous to place too great reliance upon averages when dealing with distributions, and this is particularly the case with the head index. In a map of the world on a very small scale, it is impossible to avoid broad generalisations which mask important racial movements; as an example, one has only to compare Arabia and India in Prof. Griffith Taylor's diagram of Biasutti's pl. vii. with the original.
