Clearly Manouvrter’s method gives results in this case differing almost 1 centim. 
from mine for both sexes. They have ranges 2*6 centims. and 7'9 centims. for male 
and female as compared with my 1*8 centim. and 4*2 centims. respectively. Our 
method of taking the means of the results is not, however, very good. There are 
very few radii, and the results for that bone have little weig'nt. To properly weight, 
however, the formulse involving two or more bones is troublesome, and the increased 
exactness is so small as to be hardly v.mrth the labour. If we treat F and T, 
F and H, and F, T, H, and R as likely, d priori, to give the best result, \ve have 
male stature, 169’5 and female stature 153*3. I doubt whether this is as good 
as the previous result ; it would connote a very high sexual ratio, 1*106, which 
is contrary to what we generally find with primitive peoples. The sexual ratio 
of the above results is very high, 1*095, and it seems to me probably that in the 
difficult matter of sexing rather too large a proportion of large bones have been 
given to the male and too few to the female group. Further, the smaller radii may 
probably have disappeared, which accounts for something of the irregularity here—as 
in other cases—of the estimates from the radius. Allowing, however, for these 
irregularities we find the Row-grave population by no means so widely differentiated 
from f.he French as the Naqada race. They were, however, a tall race, taller than the
