DATA FOR THE PROBI.EM OF EVOEUTTOX TX MAX.

This Avould simply throw us back on the regression formula (8) of our tables. 
Now the order of xjm is of the order of cr/m, or the coefficient of variation, say, 
•03 to '04. Blit deviations equal to 3cr may and do occur ; hence, in individual cases 
an error of 9 to 12 per cent, might arise, if we were to assume that formula (9) can 
he replaced in all cases by (8). Accordingly, at Mr. Title’s suggestion, 1 formed the 
product of L X B X H, and correlated this product with the capacity. In tlie 
following Table IX. I give the data for Aino, German, and Naqada races

For the Naqada race we deduce the regression formidie from the above results :— 
Males . . . . C = -000352 X (L X B X H) + 372-39. 
Females . . . G = -000410 x (L X B X H) + 189-81. 
Tlie probable errors for reconstruction by aid of these are :—
