a commemoration of the Battle of Waterloo, assassinated 
an English soldier with a fork, held in his left hand. 
The cranium of another murderer, ’T)wen’’, a Welshman, 
supposed to have been 40 years of age, also from the 
Brookes Museum, presents much of the same long, low 
and narrow cylindrical form as that of the Norfolk Island 
Convict. Ail the sutures effaced in that of ’’Feron” are 
closed in this, on both sides. I have other skulls of 
criminals Avhich exhibit synostoses and Prof. Luca, in his 
tine Avork ”Zur Architectur des menschlichen Schadels” 
gives a considerable amount of evidence in the crania of 
criminals Avhich he depicts and tabulates, Avhich tends to 
shoAv that synostoses are common among this class of 
persons, and that the result is frequently some degree of 
micro-cephaiism. Prof. Luca is an independent Avitness, 
for, Avhilst lie records the tacts, 1 am not aware that he 
has alluded to the theory, that such encroachments on the 
cavity of the skull and their consequences in preventing 
the due evolution of the brain, especially the surface of 
its hemispheres, have any intluence on the moral and in- 
tellectual poAvers. It has appeared to me that such effects 
are highly probable. 
We have the testimony of numerous authorities that 
the mental poAvers of the Chinooks, Flatheads and other 
North-American Indians, aa4io practise distortions of the 
skull, are quite equal to those of the tribes Avho are con- 
tent to leave nature alone. This may possibly be the 
case, Avhere compression in one direction is compensated 
for by expansion in another; Avhilst synostotic deformation, 
especially in those cases in Avhich it results in restricting 
the cavity for the brain and of preventing its develope-
