In all these cases we see that the male is markedly more leptorrhine than the 
female* , and that Thomson's mean for males agrees with Duckworth's and her mean 
for females with Scott's. Her results differ widely from Poll's, but so do Duckworth's 
and, to a considerable but lesser extent, Scott's. It seems to me that if the paucity 
of numbers be not regarded (the probable error of Poll's ,^ mean is about 0"83), we 
must conclude that Poll measured his nasal height somewhat differently to Thomson, 
and accordingly Professor Giuflfrida-Ruggeri is not justified in contrasting his 
results directly with hers. 
If, instead of working with means, we use the loose threefold category appa- 
rently approved by Professor Giuffrida-Ruggeri, we find :

Results at once flow from this table which bear strongly on Professor Giufifrida- 
Ruggeri's classificatory table (p. 4, loc. cit). In the first place Duckworth's own 
measurements absolutely confirm Thomson's, although with his few cases it was 
hardly to be expected that so close an agreement would arise, and it must be of course 
somewhat fortuitous. Poll's results differ widely from those cited by Giuffrida- 
Ruggeri from Poll, simply because he has taken from Poll the data Poll gives for 
* This sexual difference is fairly general. Thus we have :

and the general tendency is for the female to be more platyrrhine than the male. 
t These results do not accord with those Professor Giuffrida-Kuggeri attributes to Thomson. 
Thomson has only 21 available nasal indices for females, not 22.
