Note 1514 — THE ETHNOLOGY OF ANCIENT BRITAIN

Professor W. Z. Ripley thinks that the difference is nearer 1·5 than 2 (L’Anthr., vii, 1896, pp. 516-9); while Mr. Gray (Man, ii, 1902, No. 41, pp. 50-1) regards the method of subtracting 2 as ‘illogical’, and would subtract 8 mm. from the breadth and 10 mm. from the length.

Certain minute differences between Broca’s system of measuring the skull, which is followed everywhere except in Germany, and that adopted by the German anthropologist, von Ihering, are lucidly explained by Otto Ammon (L’Anthr., vii, 1896, pp. 676-82) and Professor Ripley (The Races of Europe, 1900, p. 593), but may, for the purpose of the present inquiry, be safely disregarded.
