[The Cephalic Index.] 7. Next taking the cephalic indices—on glancing the eye down the column containing these data, it will be seen that all the castes have cephalic indices, showing the formation of the head to be dolicho-cephalic without exception, those of the castes Dhânuk, Arakh, Nat and Kewat being slightly sub-dolicho-cephalic, thus presenting a very marked contrast to the head of the Burman, which is decidedly brachy-cephalic, showing an index of of 83·1. The Burman, however, belongs to the Mongolian type of race, and nothing further need be said about him here. Out of four hundred and fifty adult males of the Brâhman caste the average cephalic index is found to be 73·7, a figure practically the same as that found by Mr. Risley, the lowest index being that of the Bhât, and the highest (of course excluding the Burman, who is Mongolian) that of the caste Kewat. 8. Again, if we take one representative caste out of each of the main divisions and compare them thus:— ====================================== Division. | Caste. |Cephalic | | Index. ~~~~~~~~~~~~~~~~~~~~+~~~~~~~~+~~~~~~~~ 1.

In the above investigation both the facial angles of Camper and Cuvier have been invariably taken and recorded, but as the latter is scientifically more accurate, at any rate on the living subject, it will suffice to notice the results under the latter measurement alone, as it gives us more accurately the true or sub-nasal prognathism of the individual. 10. All the measurements of facial angles were taken with Broca’s facial goniometer, by far the best instrument for the purpose. All human beings, no matter to what race they belong, are, of course, prognathous, the only difference being one of degree, the more acute angle shown indicating naturally the greater degree of prognathism.
