Museum of the Koyal College of Surgeons of England, finds 

 the average male capacity to be l,309cc, and the female 

 l,140cc. Broca, in seven specimens, finds the male to be 

 1,452, and the female 1,201. J. Barnard Davis, six male 

 1,392, four female 1,273. Topinard, male, 1,376, female 

 1,103. Mr. W. L. H. Duckworth, in two male skulls in 

 the Cambridge University collection, finds a capacity of 

 1,130. 



These figures combined give an average capacity of 

 l,323cc. in the male, and l,161cc. in the female, thus classing 

 the Tasmanian skull as micro-cephalic. 



Cephalic Index. 



No. Average. Minimum. Maximum. 



Class. 



Male ... 6 74-0 73-1 75-6 Dolicho-cephalic 



Female ... 5 77.0 75-4 78*5 Mesati-cephalic 



Total ... 11 75-4 731 78"5 Mesati-cephalic 



Our average of 11 skulls gives a cephalic index of 75*4, 

 which places these specimens in the mesati-cephalic class. 

 The males, with an index of 74*0, have a longer skull than the 

 females, 77*0. The variatiou, however, is small, 5*4. Broca, 

 in 10 Tasmanian skulls, finds a cephalic index of 76 11*. 

 Barnard Davis, in 17 Tasmanians, one of 75'6f. Topinard 

 finds an index of 77'4 in the male, and 74*9 in the 

 female^, which makes the female skull the longer in propor- 

 tion, contrary to our experience. Flower gives an index of 

 76*3, but as his measurement of length is taken from the 

 ophryon instead of from the glabella, as in the other authors 

 quoted, this makes his index higher than it would otherwise 

 be§. Duckworth, in the two Cambridge skulls, finds an average 

 cephalic index of 731. These figures combined therefore 

 give an average cephalic index of 75*4, which, strangely 

 enough, is the average of the skulls in the collection at the 

 Tasmanian Museum, and classes the Tasmanians as mesati- 

 cephalic. 



Vertical Index. 



This table of vertical indices shows that our collection of 

 skulls should be classed as Tapeino-cephalic, having an
