As would be expected, however, all possible combinations of these primary groups are now abundantly present. Thus the population of this State presents unlimited opportunities for research in the problems of physical anthropology growing out of race mixture.
The present study deals with the classical blood groups in Whites and Negroes and in mixtures of these two races. The observations were made in the city of São Luiz and in the village of Santo Antonio dos Pretos (Municipe of Codó), a little over 300 km southeast of the former.
The Negroes were selected on the basis of their well-known physical characteristics. The series totals 198 and includes representatives of different African groups.
