A close inspection of these increments will show that the general trend 

 of all is similar. The same peculiar difference between the growth curve 

 for white girls and that for boys is observable among both Indian and 

 mixed childi-en. For gii-ls, the adolescent period of increased growth 

 reaches its maximum at about the same time for all alike; for boys, the 

 Indians seem to reach it later tlian the mixed and whites. In case of 

 both mixed bloods and Indians, the pre-adolescent acceleration is more 

 in evidence than among white children, the mixed bloods again falling 

 nearer the white standard. As the number of cases is small, we may 

 check this result by a similar treatment of the values for weight.
