need to largely increase the number of crania dealt with, whenever this can be 
done without introducing doubts as to homogeneity. 
In our present investigation we have been lucky in obtaining, — not what the 
mathematician would term a statistically adequate series, we cannot get skulls 
like crabs, butterflies, or leaves by the thousand, but — an unusually long series for 
a craniometric investigation. Professor Karl Pearson requested Professor Flinders 
Petrie before he left for Egypt in 1894 to procure for him if possible 100 skulls of 
a homogeneous race. Early in 1895 Professor Petrie reported that he was able to 
send to England a remarkably fine anthropological collection — the entire skeletons 
as well as crania — of the now well-known Na(]ada race, embracing more than 
400 individuals. This collection was packed and brought to England at the expense 
of the late Mr A. B. Pearson -Gee, who, hearing that the project might fall through, 
generously provided the requisite funds. The whole material was deposited at 
University College, where Mr Herbert Tliompson in 1895 made for Professor 
Pearson five measurements on 301 skulls ; these were used in Professor Flinders 
Petrie's Naqada and Ballas. In 1896 Dr Ernest Warren undertook the measure- 
ment of the chief bones of the skeletons, and his results were published in the 
memoir of 1897 : An Investigation of the Variability of the Human Skeleton : 
with especial reference to the Naqada Race*. Shortly after, at the suggestion of 
Professor Pearson, Miss C. D. Fawcett undertook to complete the measurements 
on the crania. We have thus during a number of years had at our disposal a 
splendid collection of upwards of 400 skulls. We cannot too heartily thank 
Professor Flinders Petrie for his kindness in this matter. We are also much 
indebted to Dr E. Warren for aid. Where possible his sexing of the skeletons has 
been adopted for the sexing of the skulls, because that sexing was based on a very 
careful process {loc. cit. p. 138) of examination of the long bones, the hip-bones, 
and the skulls. When this determination was not available appeal was made to 
Professor G. Thane's determination of sex used in the case of the skulls measured 
by Mr Herbert Thompson. Lastly in those cases — fairly numerous — in which the 
skulls had no corresponding skeletons or had not been sexed by Professor Thane, 
Dr Warren has most kindly come to our aid, and given us his judgment as to sex. 
It will be found in the tables that the skulls are classed as male ((/"), female ( $ ), 
doubtful but probably male (J* ?), doubtful but probably female ( $ ?), and finally 
sex quite doubtful (?). For the remarks on the anatomical peculiarities of the 
skulls placed in the last column of the tables of the appendix of measurements we 
have to thank in particular Professor W. F. E. Weldon, F.R.S., who most kindly 
went through the whole series with this end in view, and Professor G. Thane 
who examined some thirty selected crania.
