a singular bone -harpoon, with double barbs, facing in one 
direction, and a third reversed barb at the base (the last no 
doubt being intended to serve as an attachment to the shaft), 
a bone bead hexagonal in form to a section along a plane 
through its axis and incised with rectilinear ornamentation, 
and three flint flakes. 
Just as the Eoman layer thinned away in each direction, and 
came to the surface inside the cave and outside down the screes, 
so did the JN'eolithic layer thin away in each direction, and run 
into the Eoman layer. In 1874 a well- worked small flint 
implement of lanceolate-leaf outline, similar to some figured 
in Mr. John Evans' valuable book * was found lying on the 
side of a cutting through the screes, and had probably fallen 
out of the Neolithic layer above. It was unworked on the 
flat side. Sections across it would give at ^ from the point a 
triangular, and near the bulb a plano-convex, outline. 
Amongst Mr. Jackson's finds inside the cave was a small adze 
of melaphyrf , and the late Mr. Denny showed me this in the 
Leeds Museum, side by side with one from the South Sea 
Islands, so exactly similar, except in its larger size, that they 
might have been made by the same workman. So uniform 
is the teaching of the school of necessity ! It is probable 
that this interesting relic is also from the Neolithic layer. 
We have now got so far back in time in our account of 
the researches as to be already far below the earliest records 
of history. Let us see what light the cave throws upon still 
earlier and obscurer ages of the area now called Yorkshire. 
THE BEDS INSIDE THE CAVE. 
The Upper and Lower Cave-Earth. — In describing these I 
shall give the chief prominence to the Section as it appeared 
in Chamber D, the right hand hall of the cave at its present
