The secondary differences which distinguish them, are doubtless occasioned, on the one hand, by the number of crania employed by the two authors to obtain their means; on the other, from some diversity in the use of these materials. M. Pruner Bey distinguished the sexes, which are united by M. Broca: the latter has placed in one group the Hottentots and Bosjesmans, separated by M. Pruner, etc. From M. Broca’s table it appears that the mean of all these indices, leaving deformed skulls out of the question, is 0·78. From a numerical point of view this would be that of true mesaticephaly. The mean group ought, it seems to me, to descend equally as it rises, and consequently to absorb at least a part of M. Broca’s sub-dolichocephali. In fact, upon inspecting the two tables, it appears that the indices above 0·74 and below 0·79 comprise the greater number of races belonging to the three fundamental types, and taken from all parts of the world. It seems to me that true mesaticephaly should be comprised within these limits. I do not, however, propose that those which have been adopted should be changed.
