P. TOPINARD, Éléments d’Anthropologie générale, p. 620. The
value for African negroes is here very small. Another series
quoted by Topinard (_Ibid._, p. 622), consisting of 100
skulls of each group, gives the following averages:
Parisians, 1551 cc.; Auvergnats, 1585 cc.; African negroes,
1477 cc.; New Caledonians, 1488 cc. (a misprint in
Topinard’s book makes this appear as 1588 cc.).
