1 "Catedra de Tecnica Forense de la Facultad de Farmacia de la Universidad de Chile" and
the "Laboratorio de Policia Tecnica de la D. General de Investigaciones," Director: Prof. Dr. L. Sandoval S., and the "Instituto de Histologia de la Universidad de Concepción" (Chile), Director: Prof.
Dr. C. Henckel.
The authors present a sero-anthropological study of 205 Mapuche Indians
from Cautín (Chile). There were 86.8 per cent of group O, 8.3 per cent of subgroup
A1, 0.5 per cent of subgroup A2, 3.4 per cent of group B, and 1.0 per cent of subgroup AB.
The 3.4 per cent group B in the series may be due to crossing with whites or to
the fact that this group was always present in Mapuches even before contact with
whites.
The frequency of the standard Rh factor percentage is very high (98.6 per cent)
but not 100 per cent as in the data of North American investigators.
