165 
tons of races offering most important cranial differences, and 
since it is not found in all the individuals of the same race 
at Cefn and Terllii Chwareu. This is the first case of its 
being noticed in any skeleton in Great Britain. 
The relation of these interments to history is unknown, 
and there is no clue to the race of men by whom they were 
made. Besides the Teutonic and Celtic and Iberian races 
which have successively occupied Britain, there were most 
probably other races of which the very names have perished. 
Till we can be certain that this is not the case, it will be 
impossible to assign remains of this kind to any given race 
by an appeal to cranial and skeletal characters. A flint 
flake in the cave corroborates to a certain extent the Neo- 
lillni character of the interments, which were undoubtedly 
made by men of the same race. The chambered tomb was 
of a class common to France, Britain, and Scandinavia, 
termed by Dr. Thurnam ‘gallery-graves/ and by Professor 
Nilsson ‘gangraben.’
