the Paris Catacomb skulls (Table III.), but the homogeneity of this series 
Pearson doubts. 
The hundred Australian aboriginal skulls dealt with in this pa.per 
were obtained from the collections in the recently established Museum 
of the Anatomical Department of the University of Melbourne and the 
National Museum, Melbourne, and for access to the former collection I 
am indebted to the Professor of Anatomy, and for the latter to the Director 
of the Museum. The crania are numbered serially one to a hundred, and 
with each one is placed the number allotted to it in the museum in which 
it is located. It will be observed that the crania in the Anatomical 
Department of the University of Melbourne are numbered according to 
the system adopted by Martin (24) for Physical Anthropology and Anthro- 
pological Bibliography, and alongside this system number is placed the 
serial number of the skull. 
The crania are those of adult aboriginals from Victoria, New South 
Wales, South Australia, and Queensland. Of four, the exact State whence 
they come is not known. The number is therefore as follows : — 
Victoria 
. 85 
New South Wales 
. 4 
South Australia . 
4 
Queensland . 
. 3 
State not known .

The measurements have been taken in accordance with the directions 
laid down by the Monaco International Commission of 1906 (20), by means 
of the instrument known as Hepburn’s Improved Craniometer Callipers, 
and the readings recorded to the nearest millimetre. 
Table I. records the whole of the skulls under review in this paper. 
They are separated into male and female, and numbered serially 1 to 
78 for the males, and 1 to 22 for the females, making a total number of 100. 
Opposite the serial and museum numbers of each skull is placed, in 
tabular form, the corresponding length, breadth, and height. 
Table II. furnishes an abstract of the results obtained for the crania 
under review, and gives the mean, the standard deviation, and the coefficient 
of variation, with the probable errors of length, breadth, height, cephalic 
index, height index, and breadth-height index of a hundred unsexed skulls, 
and of these separated into male and female. 
Table III. gives the standard deviation and coefficient of variation for
