520 FRETS, THE INDEX CEPHALICUS. 
JOHANNSEN would like to introduce a correction by accepting a 
definite length as a normal length and consequently one index as 
a normal index. To a given index one adds, or substracts from it, 
the difference of the class-index and the normal index. 
JOHANNSEN will correct the index by starting from the length. 
Now we find for breadthclasses analogous but inverted rela- 
tions as with lengthclasses. When dealing with indices we have 
to consider this too. F.i. we found that the female is a little more 
brachycephalic than the male, but considering the lengthclasses it 
appeared that for the same lengthclasses the female is a little more 
dolichocephalic than the male and we remarked that the first 
mentioned difference might result from the small headlength; the 

smaller lengthclasses being more brachycephalic than the larger 
ones. Now we find that for the same breadthclasses the female is
