at Brixham, containing similar remains, has been explored 
by Mr. Pengelly and Dr. Falconer, but no detailed account 
of their conclusions has been published. Mr. Vivian, who 
took part in the examination of Brixham Cave, declares his 
opinion that the flint implements found there, one of which 
was six inches long, were introduced under precisely the same 
conditions as the fossil bones and teeth. Some were found 
at the depth of two feet in the diluvium. 
Mr. M'Enery's MS. is very fragmentary, rather materials 
for a memoir than an orderly treatise, so that it is difficult 
to reduce his scattered facts and remarks to a distinct 
arrangement ; and the dispersion of his collection prevents 
our deriving from them an elucidation of his MS. He may 
even seem to contradict himself, when different portions of 
his journal are compared together. The fact appears to be 
that he wavered in his own conclusions. An eminent 
geologist, who knew him well, says, " M'Enery had no doubt 
whatever as to the occurrence of flint implements in the lower 
accumulation with the extinct animals ; this, I know, from 
repeated conversation with him. But Buckland would never 
hear of it : hence the confusion in his views, when he came 
to write his account of the cave and its contents." j 
He speaks of the flint implements found in the lower 
deposit as rude compared with those of the upper ; but there 
is no specific account of the difference. From the drawings 
of two of them, which are of larger size than the others, 
they appear to have approached in form to the hatchets of 
Abbeville and Amiens ; but no account is given of the part 
of the cave in which they were found, so that we cannot 
derive from them confirmation of the conclusion suggested 
by other collections of flint implements, that two distinct 
seras can be traced in the history of their use. Those which 
have been found in the diluvial gravel have marked differences 
from those which occur in British or Celtic tumuli. The
