[Vol. XXIII, 1922. J P. C. Mahalanobis : Analysis of Statures. 7 



The special significance of the present material is that it does re- 

 present a mixed race which has interbred and whose component 

 races are still in a pure form. 



Plan and Scope of the Paper. 



Dr. Annandale took a very large number of measurements 

 extending to forty different characters. But the records are not 

 complete in each case. As I have already mentioned a series of 

 200 has been obtained for seven l metric characters. A second 

 group 2 consists of about T20 to 180 and a third 3 of 50 to 100 

 complete records. In addition eye and skin colour were recorded, 

 as also observations on hairyness in all cases. 



In the present paper the frequency distribution and variability 

 of stature has been discussed at some length. Certain points 

 have been considered in great detail, much of which it will not be 

 necessary to repeat in subsequent parts. 



The second part (material for which is nearly ready) will contain 

 a study of the frequency distribution and variability of individual 

 organs included in the first group. Correlation between the or- 

 gans of the first group will be next discussed and after that the 

 study of the second and the third group will be taken up. Finally 

 I hope to discuss the distribution and correlation of eye, hair and 

 skin-colour in a separate paper. 



I should make nry position quite clear; I frankly confess 

 that I know very little of anatomy. My work on the data supplied 

 has been purely statistical. 



Some of the results may appear to be thoroughly unconvention- 

 al or sometimes perhaps even startling in character. With such a 

 short series, it is of course impossible to lay emphasis on the 

 numerical value of any particular constant. But I would like 

 to draw the attention of Anthropologists to statistically signi- 

 ficant magnitudes as not unworthy of careful study. I have 

 contented myself with pointing out statistical results and have 

 refrained from drawing Anthropological conclusions. 



The chief object of the present study is to invite the attention 

 of Plrysical Anthropologists of India to the importance of the 

 application of accurate statistical methods to their ' f crude :> mea- 

 surements. As some of the technical terms may be unfamiliar
