30 . A. CRANIOMETRIC STUDY 



ever, I found that the three horizontal areas in the Melanesian 

 skull exhibited a very decided degree of difference from those 

 of this Micmac skull in rej>;ard to their relative proportions. 

 Fig. 10 has been designed to demonstrate this comparative 

 difference. The Micmac skull (which is to the right) is an out- 

 line sketch of the photograph shown in Fig. 11 and is not 

 drawn to the same scale as the Melanesian skull (exhibited 

 on the left). In the latter, the lower horizontal area shows 

 a marked reduction in depth when compared with the Micmac 

 skull, and is due of course to pronounced foreshortening, the 

 result of an excessive degree of prognathism in this case (an 

 alveolar index of 106.7). On examining the two upper hori- 

 zontal areas in the Melanesian skull it is at once observed 

 that they are almost exactly equal in depth. (Fig. 10). 



It is evident, then, that this method disclosed a very pro- 

 found inter-racial difference, so far as these two individual 

 skulls were concerned. Indeed, the results look so hopeful 

 and encouraging that I intend to apply this method to an ex- 

 tensive series of skulls, when the opportunity arises, and would 

 cordially invite others who are interested in craniology to do 

 likewise. 



The writer cannot conclude this paper without expressing 

 his cordial thanks to Dr. J. W. Fewkes, Chief of the Bureau 

 of American Ethnology, and also to Dr. E. Sapir, Head of 

 the Division of Anthropology, Geological Survey of Canada, 

 for valuable contributions of literature, and also for numer- 

 ous references to the bibliography relating to the Physical 

 Anthropology of the North American Indian. The comple- 

 tion of this memoir would have been rendered impossible 

 without the valuable help of these two gentlemen, which is 

 hereby gratefully acknowlcflgcd by the author.
