Table III. deals with the hasi-iiasiil length, and shows the pro- 

 visional mean, the true mean, and the standard deviation of same, 

 and the co-eflficient of variation, together with the numbers of ex- 

 amples of each race. The six races are arranged in the order of the 

 true means of the basi-nasal length. 



From this we infer that the basi-nasal length is shortest in the 

 pure races (Andamanese, Veddahs and Tasmanians), longest in im- 



impure races, like the Chinese and modern Italians, and longest of all 

 in the doulitfuUy pure A\istralian. 



Table IV. deals with the basi-prosthionic length for the six 

 races in the same way. The Australian, again, has the longest basi- 

 prosthionic axis, and the pure Veddahs and Andamanese have the 

 shortest. The Tasmanians and Italians have changed places, and 

 the Chinese are in the same relative position as before.

In Tal)le V. are set forth the gnathic indices for the six races, 

 whence we learn that Italians, Veddahs, and Chinese are ortho- 

 gnathous, the last-named being on the ortho-mesognathic borderline. 

 The Andamanese are distinctly nie.sogiiathic, as arc also the Tas- 

 manians, but, as already indicated, it is, on the whole, fairer to re- 

 gard the Tasmanian as on the meso-prognathic borderline, a remark
