The frequency with which the various teeth of male and female adults 
were affected with dental caries is shown on a per thousand basis in the 
following table, in which calculations are made to full figures. The actual 
number of teeth affected was 126.

BLOOD GROUPS 
An endeavour was made to obtain as many samples as possible of 
blood for grouping purposes in the expectation of being able to promote 
still further the view which published data strongly support, namely, that 
the blood of the North American Indian belongs to group O (group 1 
Jansky) and pure Indians are, therefore, universal donors: their blood 
may be transfused into the vessels of individuals of any and every group 
without causing deleterious effects. Further, if the findings sustained this 
contention, we should be enabled to call to our aid one other characteristic 
(in addition to the colour of the eye, type of hair, etc.) which would assist 
in distinguishing Indians of pure stock from those who are partly white. 
In all, 123 samples of blood were tested, these being taken from 114 
adult and old men, one woman, and eight boys, of whom some were pure 
Indian; and others, breeds. Of these 123 samples, 83 per cent belong to 
group 0; 8 per cent to A; 9 per cent to B; 0 per cent to AB. The data 
concerning the individuals are to be found in the appendix. 
The following table, No. IV, records the actual and the percentage 
distribution of the blood groups of the four bands regarded both singly and 
collectively.
