1910-11.] The Place in Nature of the Tasmanian Aboriginal. 47 
suprainial part of the occipital squama formed a large rounded protuberance 
in the female skull, a character which may perhaps be regarded as sexual 
rather than racial.” 
As we have found the same suprainial bulging in many of the cadavera 
— all of Caucasian origin — in the ordinary routine work of the dissecting- 
room, we are inclined to agree with Turner that, whatever the explanation 
of this suprainial prominence may be, it is certainly not racial. 
Having selected a working base line and the points between which that 
base line was to be drawn, the rest of the observational points presented no 
difficulties. Schwalbe’s procedure and instructions were explicitly followed, 
and those already mentioned as having been selected by us are illustrated 
in fig. 1 — a median sagittal section of an adult male Australian aborginal 
skull. 
In Table XXVIII. are set forth the individual measurements of the 27 
observations made by us upon our series of 52 Tasmanian crania. In 
this table are recorded in the upper four horizontal lines the serial number 
of the skulls as used in the present investigation, the present location of the 
skulls, their original numbers, and their probable sex. In the three left- 
hand vertical columns are set forth the numbers and names of the 
observations recorded and the nature of the indices employed. In the 
vertical columns 1 to 52 inclusive are set forth the individual measurements 
and indices of each skull. The four vertical columns on the right record 
the number of observations made, the results worked out at an average, 
together with the minimum and maximum figures for that particular 
observation. Thus the number of observations made on the glabella-inion 
length was 44, giving an average length of 173T mm., a minimum of 157 
which occurred in skull number 10, and a maximum of 188 in skull 29. 
In our previous writings on the discovery of these crania (1 and 8) we 
pointed out that there was some dubiety as to the purity of one or two of 
the examples here dealt with. In order to test this point we have indicated 
by a -1- or a — the skulls in which the maximum or minimum figure 
occurred : thus at the junction of the columns 10 and 1 the glabella-inion 
length 157 is marked with a minus, which thus indicates the minimum 
figure recorded under this observation, and also shows at a glance in which 
skull the minimum figure occurred. As this procedure has been adopted 
uniformly throughout, it makes it perfectly clear that in no part of the 
table is there a preponderance of plus and minus signs, and consequently 
we regard this uniformity in the distribution of such signs as an additional 
argument of the purity of the crania dealt with. 
It will easily be understood that it was not possible to record all the
