to them as ' superior ' and ' inferior ' inions. We place here the values of the 
measurements taken on the Benbham head. Professor Thane with his usual kind- 
ness consented to take the critical arcs and diameters independently, and his 
measurements agreed within a millimetre with ours.

We place these measurements here because they may be of interest for other 
than our immediate purpose, merely remarking that difficulty of access or other 
reasons render some very doubtful. We notice at once that Jeremy Bentham 's 
head is closely identical with that of the mediocre or average Englishman. 
Apparent exceptions are the very arcs which Dr Beddoe measures, but the 
difiference here is, we believe, solely due to the difficulty of allowing for the flesh, 
and to a less extent for the hair. The only real exception we believe to be the
