In the following table the examples are derived from Dr. J. B. Davis’s tables, with the exception of the Peruvians. For these I have availed myself of Dr. Jeffreys Wyman’s careful observations on the large collection in the Peabody Museum, the results of which confirm Dr. Morton’s earlier data. One further fact, however, may be noted as a result of my own study of Peruvian crania, amply confirmed by the published observations of others, namely, that while the Peruvian head unquestionably ranks among those of the microcephalous races, the range of variation among the Peruvian coast tribes appears to be less than that even of the Australian. Of this there is good evidence, based on the comparison of several hundred crania. But exceptional examples of unusually large skulls may be looked for in all races; and a few of such abnormal Peruvian or other skulls would modify the mean capacities and weights in the following table. Nevertheless the average results, as a whole, are probably a close approximation to the truth:—
