Physiognomy of British Columbia Coastal Indians. 29

The Mongolian spot was noted in 12 of the children whose blood groups were taken. The
case shown in Pl. V, Fig. 9, in a child of two years, is more or less typical. Her grandfather was
one-quarter white. The upper spot is of the discrete type and is usually just at one side of
the top of the natal cleft. It is frequently solitary but it is often, as in this child, accompanied
by a larger diffuse spot which is here on the right side of the top of the cleft. Another child
-of three years had her back pretty well covered with the bluish black stain. It is already known
(see Gates, 1929, p. 317 ff.) that the so-called Mongolian spot is found in all pigmented races
-and shows much variation, usually disappearing in childhood.

One woman at Bella Bella had an Indian mother and Japanese father! (Pl. I, Fig. 1).
She and her 7-year-old daughter (Pl. I, Fig. 2), who is one-quarter Japanese, were both in
blood group O, but a son aged two was the child who gave first an O and later an A blood test.
His father was probably a white man and he has a very light skin colour.

Discussion of Blood Groups.

The results of blood group testing have developed so rapidly that there is still much room
for speculation regarding their racial significance. That both A and B are inherited as Men-

delian differences is established, and that the A, B and O factors are multiple allelomorphs,

i.e. alternative conditions occupying the same locus in one pair of chromosomes, is now generally

In 1928 the senior author found a Japanese married to an Indian woman on the Mackenzie River.
