Mistaken Identity.— One of the so-called thirty-six imple- 
ments— No. 3 in Table IV. of the Report— has since been 
found to be “ merely a fragment 
of slate, nearly covered on one 
side with stalagmite/ * But 
this slight mistake of a piece 
of slate for a flint implement is 
happily balanced by an opposite 
error, by which a piece ot flint 
has been mistaken for a bone, 
and described as “ a fine small 
tibia ”;t and the care with 
which the examination had been 
made is indicated by the animal 
to which it belonged not being 
determined, a note of interro- 
gation being put to show that 
there was doubt on that point. 
The Plaster Cast of a Flint- 
knife . — I have before stated that 
I purchased in the cavern, in 
1 874, three casts of a very per- 
fect flint-knife, said to have been 
moulded from one of the knives 
found in the cavern. That such 
spurious articles had before been 
so represented, and sold to 
visitors, is now confirmed by 
the testimony of Mr. T. K. Cal- 
lard, F.G.S., who purchased one 
of the casts several years ago, 
believing it to be, as he was 
informed, a model of one of the 
knives found in the cavern. J 
The subject was brought before 
the British Association for the 
Advancement of Science at Bris- 
tol, in 1875, and the whole 
history of these spurious casts made known. It is sufficient 
for my present purpose that it was then acknowledged that the
