The table illustrates several important points, thus : 
(i.) We obtain less average error by estimating with H than LL, c»r the capacity of 
the skull is better determined from the auricular height, than from the total height 
of the skull. 
(ii.) If we exclude tlie series for which the values of the capacity seem to be 
doubtful, i.e., the Badenser and French, AA^e obtain (Ijracketed numbers from (10) his, 
footnote, }). 247) a mean error of about 1‘2 per cent, and a maximum error of 2‘5 per 
cent. For the series as a whole Ave have a mean error of about 2 "4 per cent. Avith a 
maximum error of 4 per cent. 
The latter occurs in the case of the Parisian French ; but I have not the least 
hesitation in asserting that the capacities of the French skulls as deteiinined in 
France, are quite incomparable Avith the capacities as determined by German liiA'esti- 
gators. I believe the French ca]xicity is GO to 80 cubic centims. beyond its true 
value, and I hold that my formula determines that A’alue far more closely than the 
mean of the numbers (1560) given by Broca’s MS. registers. 1 do not think it can 
differ by more than a feAv cubic centimetres from 1499, and this difference is probably 
in defect. It will be seen that the Munich French skidls are somewhat smaller than 
the Parisian French skulls, but this does not account for the Avhole difference of 87 
cubic centims. found by German and French determinations. It is largely a question
