ANTHROPOMETRY IN INDIA. 199 



than the eastern, but in other respects no great differences 

 appear in Risley's tables, except that his frontozygomatic 

 index (the proportion borne by the minimum breadth of 

 the forehead to the maximum of the zygomata taken as 

 100) is larger in Sikkim than in Chittagong as 76 to 74. 

 Topinard, in his masterly review of Risley's work, objects 

 to this index as of little value, because the minimum frontal 

 breadth gives little or no indication of the breadth of the 

 frontal lobe. The really valuable index, as he shows, is 

 got by comparing the Stephanie or maximum frontal breadth 

 with the zygomatic. But in the living subject this is 

 extremely difficult ; and though I myself employ Topinard's 

 index with profit, I am conscious that my data are often 

 wide of the fact. On the other hand the fronto-minimal 

 plan is easy though untrustworthy, and on the whole and 

 in the main, or in a certain number of cases, does point in 

 the desired direction. Thus the index so gotten singles out 

 the Brahmans from the other Bengalis (82*4, the next in 

 order being the respectable caste of Kayasths with 79*3), 

 and thus brings them into line with the nine Punjabi castes 

 or tribes, who with the exception of the Kachis in the N. W. 

 Province are the only ones which rise above 80. Both 

 sections of Mongoloids have faces longer as well as broader 

 than Hindus, whence the vertico-kephalic index, or propor- 

 tion of the maximum breadth to the total height of the 

 head (chin to vertex), is not very significant. ] And I can- 

 not help entertaining serious doubts of the entire trust- 

 worthiness of the figures for Oudh and the N.W. Province, 

 in which I seem to detect a marked personal equation,
