The relationships of the Austric-speaking tribes of India, with special reference to the measurements of Hos and Saoras
The total material dealt with in the paper is not large, and that small series are being used to represent very large populations. It is also less valuable than it should be owing to differences in methods of measurement, and some uncertainty as to whether data collected by different observers are truly comparable even in cases where they followed the same technique. It seems to be safe to assume that certain of Risley’s measurements can still be used with profit, and that his means are not affected very markedly owing to the fact that the subjects were selected. Above all the number of characters used is not sufficient to give reliable estimates of racial affinity. Recognising these limitations it appears to be adequately demonstrated that four distinct ethnic groups are represented by the series considered,viz.,
Saoras (possibly allied to Oraons and others).
Hos, Mundas and Bhumij (Austric-speaking).
Kayasthas and Brahmins.
These four appear to be quite distinct, but it is extremely probable that there are transitional types between some pairs of them, and data for these will be required in order to reveal their ethnic relationships.
