My records oi negToes(3), of white students ( 4 ) , and of the Filipinos 

 suggest that comjDosite types (elementary species?) of men when crossed 

 with opposite types follow the laws of Mendel for not many generations, 

 then begin to blend, and eventually fulfill the requirements of my scheme 

 delineated above. At present all mixed races are probably in a con- 

 dition of spurious Mendelism or no Mendelism. Among tlie negroes in 

 America the Hottentot is rarely seen, the KaiBr is often encountered, 

 and the Guinea Coast negro is abimdant, but the majority of the negro 

 population represents a variable blend of different negro types, and a 

 large numljer of mixed bloods. Among 1,000 students at Ann Arbor I 

 observed a few of each of the types of Europe, such as the Iberian, 

 Northern, Alpine, Celt, Littoral, and Adriatic, but the majority of the 

 students were variable blends, and the pure types were not exactly like 

 the prehistoric types of Europe from which they were probably derived, 

 although similar to them in many ways. During the past year my 

 anthropometric investigations have included the Filipinos of many prov- 

 inces, but especially the Igorots. Here as elsewhere pure types are rare 

 and blends are plentiful. Three primary types are found among the 

 Igorots. However, none of these are pure, but one type resembles the 

 Negrito, another, one of the prehistoric types of Europe, while the third 

 is unlike either of the others, but not a blend of the two. The majority 

 of the Igorots represent a variable blend, and they have been so long 

 isolated that a condition of no Mendelism has been reached. There is 

 conclusive evidence of the persistence of type, ^-et the tendency to blend is 

 enij)hatic.
