Abstract
PROF. R. RUGGLES GATES described in a paper read on September 8 at Leicester before Section H (Anthropology) of the British Association the results of his recent work on the blood groups of the coastal Indians of British Columbia. Of 300 individuals tested, 14 per cent were A and the remainder 0 with the exception of two individuals who were B, a result which seems to indicate that before intermixture with white blood occurred, these Indians, like those in other parts of North and South America, were originally all O. The present populations of north-eastern Asia now have a high percentage of B as well as A, hence the emigration from Asia to America must have ceased before the populations in Asia from which the Indians were derived became impregnated with A or B.
