relatively pure blends. Between a' and a" are the other relatively pure 

 blends. Between a" and a" are the impure or variable blends (repre- 

 sented by type M and A and the Iberian). If at any time, by reason 

 of certain conditions, one type increases in numbers more rapidly than 

 another, then the relative proportion which at present exists will be 

 altered. The Australoid now predominates, and if it was not previously 

 present in equal numbers with all the other types, then it is increasing 

 more rajjidly than the other types. Among the Japanese the types 

 selected are not pure, but there is a general resemblance among them 

 in such characters as face width, stature, upper arm length, and hip- 

 shoulder index, in which they differ from the other groups. The small 

 number of blends is therefore counterbalanced by the homogeneits' of the 

 individuals to such an extent that all the Japanese may be considered as 

 blends, and the types merely resemble their prototypes of tlie other 

 groups. In consideration of this and because of the small number of 

 individiials who are all from the same culture level, the Japanese are 

 omitted from the scheme for heredity. 



The Manila Students are composed of at least three comparatively 

 pure types : Iberian, Primitive, and Australoid, and of several other types 

 that are not so definite: the Alpine, B. B. B., Modified Primitive, Cro- 

 Magnon, and Adriatic. The purest of types are the Iberian and Prim- 

 itive, the Iljerian the purest of all, the Australoid not so pure because 

 it is a mixture of the two, a mixture that has had two successive stages : 

 one remote in time and one recent; the former well represented by the 

 Igorots, the latter better by the Students, which naturally makes the 

 type more variable than the two of which it is composed, they having 

 remained constant in physical characteristics through time and space 

 where not mixed with other types. However, if the types are considered 

 in connection with the blends, there is an equal number of the two 

 (types and blends), and the line S-S would represent the position of 

 the Student in the scheme for heredity if we omit the Iberian, which 

 must be placed above 3 because of its evident purity. It can not be 

 located exactly, but I lielieve it will exhibit Spurious Mendelism between 

 2 and 3. and probably in some characters it will exhibit True Mendelism 

 which would place it between 1 and 2. 



If the Primitive is a pure t^'pe, and if it has not changed its form 

 (does not represent tlie Negrito undergoing metamorphosis) throughout 

 its existence, it must be placed in a position very near that of the Iberian; 

 but if it is a modified Negrito, the type is not so pure as the Iberian, the 

 loss of kinky hair indicating metamorphosis, and it may be placed with 

 the other types in B- between 3 and 4. 



The Morgue subjects are in a condition of amalgamation similar to 

 that of the Students, although the actual number of blends which would 

 place them at M-M is less. Here again, as among the Students, the
