In future papers I hope to be able to demonstrate the prevalence of 

 certain diseases in definite morphologic types of men in the Philippines, 

 which may indicate the types that fare well in the Tropics, as well as 

 those that do not. 



Mention was made' in the beginning of the present work, of the summits 

 of the curves of stature, cephalic index, and nasal index which suggested 

 the cornfield of SchuU with its "heterogeneous collection of elementary 

 species and hybrids between them," and Spillman's explanation of the 

 elementary species on the "old Darwinian idea of gradual evolution" as 

 represented by a simple scheme which was delineated. The above selec- 

 tion of types is not an attempt to prove or disprove the application of this 

 scheme to man, but is an earnest effort to find the exact composition of 

 a mixed population. That the types fall somewhat into Spillman's scheme 

 goes without saying, and that the summits of the curves correspond to 

 different elements of the character represented by them is also true to 

 some extent. The srminiit of the cephalic index (Chart II) at TG, 

 represents the Iberian; at 78, the Australoid; at 80 and 83, as well as 

 part of 86, the Blending type; at 86, the Primitive, Modified Primitive, 

 and the B. B. B. ; at 88, the Alpine and Adriatic ; and at 9? some indi- 

 viduals of the Primitive, Modified Primitive, Alpine, B. B. B., and 

 Adriatic. The summits of nasal index and stature. are less exact than 

 those of the cephalic index. 



The gametic constitution of the types is as follows, in fulfilment of 

 Spillman's scheme : 



Iberian A'' 



Australoid A' 



Primitive A= 



Modified Primitive A* 



Modified Alpine A* 



Modified B. B. B. A« 



Modified Adriatic A" 



Blending type A'' 



A, in this scheme, represents stature, B, cephalic index, and C, nasal 

 index, with equivalents as mentioned on page '366. Many possible forms 

 are missing and those present are near the median or below, except in 

 the nasal index, where the highest extreme is almost reached. Individual 

 forms probably bridge the majority of the gaps, and a perfect series 

 could be constructed from them. 



If plants and animals may be designated as elementary species by 

 Spillman's scheme, on the "old Darwinian idea of gradual evolution," 

 with equal propriety and verity that scheme may apply to man, and 

 types selected above represent elementary species of men who have been 

 formed by the blending of diverse types, as well as by gradual evolution.
