1910—1 L.] Study of the Tasmanian, Australian, and Papuan. 27 
the breadth-height coefficient of correlation is practically constant, the 
height-length coefficient a little less so, and the length-breadth coefficient 
has the greatest range of all. These results confirm those attained mathe- 
matically by Pearson and Lee, and also show that morphologically 
the comparison of length-breadth is the most important, with height- 
length second in point of importance, and breadth-height a negligible 
quantity. 
Bearing in mind what has already been stated as to the disputed 
question of the heterogeneity or homogeneity of the Australian aboriginal, 
our final conclusion must not be misunderstood. 
We do not definitely state that the Australian is a dual type : we merely 
maintain that biometrical investigation proves that the Tasmanian is the 
purest of the three racial types here compared, the Papuan is the least pure, 
and the Australian is about midway between the two; this, however, is 
evidence which those ethnologists who maintain the duality of the 
Australian aboriginal will doubtless welcome and make the most of it. For 
ourselves, we regard this as one link in the chain of evidence concerning 
the heterogeneity of the Australian as contrasted with the homogeneity of 
the Tasmanian.
