PEOPLE OF THE SUBMERGED FOREST 37 
some unusual substance, not black as are skulls which 
have been buried in peat. In size and shape the Carnon 
skull or calvaria shows all the river-bed characters. 
The maximum length is 184 mm.; its maximum width 
137 mm. ; the height above the ear-holes is estimated 
to have been 117 or 118 mm. The width is 74-5 per 
cent, of the length ; the brain capacity must have been 
about 1380 c.c. — slightly above the average for modern 
women. 
An accurate record of another of these Cornish 
Neolithic skulls 
has been pre- 
served by one 
of the best Eng- 
lish anthro- 
pologists of the 
Mid - Victorian 
era — MrGeorge 
Busk. In 1862, 
Mr Busk gave 
an account of the 
famous Nean- 
derthal skull, 
discovered in 
1857.^ He also 
gave accurate 
drawings of cer- 
tain other ancient skulls. Amongst these he included one 
from an alluvial tin mine at Sennen, close to Land's End. 
The skull was found at a depth of 30 feet. That is all we 
know of the Sennen skull, except that it was found beneath 
the level of the sea. Where that skull is now we do 
not know — probably destroyed, so careless are we of our 
records of ancient history. There can be no reasonable 
doubt, however, that the Sennen skull also comes from 
the submerged-forest zone. Mr Busk's drawing of the 
skull 1 have copied and reproduced here. He does not, 
unfortunately, represent it either from above or from the 
' Natural History Review, 1861, vol. i. p. 155.
