as well as platyrrhyny. We may therefore safely reject Risley's hypothesis as to the nasal index being an indication of the caste.
Of the other anthropological measurements the cephalic index is another of great impor. tance. Here, too, we have the same difficulty of assigning any particular type to any particu lar caste. Among the Brahmanas of Bengal we have, according to Risley, 29 the following percentages of cephalic and nasal indices:
Cephalic Index:
THE INDIAN ANTIQUARY
Hyper-dolichocephalic (-700)..
Dolichocephalic (70-0-74.9) Mesaticephalic (75-0-79·9) Brachycephalic (80·0 and over)
Nasal Index:
Leptorrhynian (less than 70.0) Mesorrhynian (70-0-84-9) Platyrrhynian (85 and over)
Hyper-dolichocephalic (-70-0).. Dolichocephalic (70-0-74.9) Mesaticephalic (75-0-79.9) Brachycephalic (80·0 and over)
Nasal Index:
Leptorrhynian (less than 70-0). Mesorrhynian (70-0-84.9) Platyrrhynian (85 and over)

The results we obtain from these figures are that the Brahmanas are principally mesati. cephalic, but mesorrhyny and leptorrhyny are fairly well balanced among them. On the other hand the Santals are distinctly platyrrhynic; they are also mesaticephalic, but there is a large percentage of dolichocephalism among them. These results, however, do not agree. with Datta's biometrical analysis of the measurements given by Risley in his Tribes and Castes of Bengal; an Ethnographic Glossary. Though rather lengthy, I have thought fit to reproduce in a condensed form Datta's figures here as his paper 31 may not be available to all. According to Datta, the somatological type most prevalent in India is the dolichoid-mesorrhynian.
