PROFESSOR KARL PEARSON, MATHEMATICAL 
che same time it must be remembered that the stature falls within the range within 
which our chart shows that a very slight change in the long bones makes a great 
difference in stature. In case the reader should be inclined to put too great faith in FI, I 
would draw attention to the fact that it underestimates by slightly over 5 centims. the 
known stature of the fairly short Aino race, while Pj or Pn give it almost accurately 
and M fairly closely. 
The only other Bushmen I have been able to find are a male and two females in 
the Royal College of Surgeon’s Catalogue. Selecting the right members as those for 
which our formulEe and curves are deduced, we have : 
Male, F = 3r)'6 centims., H = 25'5 centims., T = 29’9 centims., R=: 20‘8 centims. 
Female 1, F = 38-0 „ H=27-0 „ T = 33-2 „ R=21-0 
„ 2, F = 37-6 „ H = 25-7 ,, T = 28-8 „ R=18-G

The estimates based on the skeleton height of these three Bushmen are : Male 
= 133‘3, female 1 = 140‘0, and female 2 = 139'0 centims. The mean error made 
by Pn is 5'9, by M 6*7, and by FI 4T centims. But it must be noticed that the last 
gives in one mstance less than the height estimated from the skeleton—a result 
which is in itself very improbable. A consideration of the values here given seems to 
show that with the mean length of bones given by Humphry the mean stature could 
not possibly have been the 137'L centims. he states. For whatever estimate we take 
of the Female 1, she must have been with bones no longer, at least 10 centims, taller
