potency to the end, as proved by tests made finally on two white nurses who were known to-
be respectively A and B. Twelve individuals were re-tested after an interval of some time.
They all gave the same result in both cases except one, a boy of two years, who tested O at first.
and A on the second trial. He was very “ white ” in appearance and possibly the agglutinogen.
was late in developing.

The general blood group results are shown in Table 1, the individuals being classified
according to their various villages and tribes.

Following the Pan-Pacific Congress in June, 1933, Dr. Ride and Professor Furuhata, in
company with Dr. Darby, took the blood groups of 203 additional Indians from the above areas,
Their results will no doubt be published in full, but the totals are given in the last lme of Table 1
for comparison with our results. It will be seen that A has risen from 12-7 per cent. in our
results to 23-6 per cent. in theirs. The aim in our tests was to take the older generation as
far as possible, so that few children were included, while theirs included a larger number of the
younger generation. The greater frequency of A and B in their results indicates an increase
of white blood in the younger generation. The y? test shows that the difference is significant.
This is in harmony with expectation on other grounds.

Something will now be said of the various Indian groups at present occurring in this area.
As may be seen from the ethnological map published by Goddard (1924), these Indian groups -
occupy successive positions down the coast, beginning with the northernmost Kwakiutl village
of Kitamaat, which is in contact with the Tsimshians on the north. This large village of
nearly 300 people is at the head of a long inlet and should therefore be more isolated. It is.
150 miles north of Bella Bella. The language is like that of Bella Bella, but the vocabulary
differs and there is a distinctive intonation. On Gardner Canal, some 50 miles south from.
