Note 58 — Chapter II
Reading edition
According to the quinary nomenclature adopted in many countries of Europe, the indices are grouped by series of five: dolichocephalic from 70 to 74.9; mesocephalic from 75 to 79.9; brachycephalic from 80 to 84.9; hyper-brachycephalic from 85 to 89.9. The two systems might be combined with advantage, as I proposed ten years ago, under the following nomenclature, which I have adopted in this work:—Cephalic index of the skull: From 69.9 and under, hyper-dolichocephalic; from 70 to 74.9, dolichocephalic; from 75 to 77.7, sub-dolichocephalic; from 77.7 to 79.9, mesocephalic; from 80 to 83.2, sub-brachycephalic; from 83.3 to 84.9, brachycephalic; from 85 to 85.9, hyper-brachycephalic; from 90 and upwards, ultra-brachycephalic.
