TRANSACTIONS OF THE PLYMOUTH INSTITUTION. 
The concrete -floor yielded chiefly small fragments of bones 
and teeth. Northward there were more bones and fewer teeth, 
and the open stalagmitic-breccia in the end, in character and pro- 
ductiveness was precisely similar to the breccia above. The close 
granular stalagmitic-breccia was less productive at the level, and 
in depth became barren. 
In the stalagmitic-breccia remains of deer were peculiarly 
abundant ; and human bones, comprising the remains of complete 
skeletons, were chiefly associated with those of red-deer, roe-deer, 
hyaena, wolf, and fox. 
In the concrete-floor remains of hog were so prominent as to 
be characteristic. Here human teeth were chiefly mingled with 
those of hyaena, wolf, boar, and badger. 
At the very end of the fissure, seven feet below the stalagmitic 
floor, and at the deepest point in the breccia at which bones were 
then found, there lay portions of a human upper and lower jaw. 
The concrete-floor was carefully examined in situ by the man 
who removed it, and every recognised fragment of bone put aside 
for my examination, The stuff was afterwards examined on a 
table under the direction of Mr. Robert Burnard. That gentleman 
also washed and picked over, with the aid of a magnifying-glass, 
some of its looser and finer components, finding a quantity of 
bones and teeth of the shrew, water-vole, and mole. The same 
results attended some of my own examinations of the clayey 
matter washed off from the bones ; and in the breccia there were, 
in addition to the water-vole and mole, bones and teeth of the 
bank- and field-vole and bat. 
Mr. Burnard then determined to trace the fissure towards Catte- 
water. When he commenced excavation, the section southward 
appeared to indicate that the entrance of the cavern lay in that 
direction, not far from the sea level. The filling was much looser, 
and consisted largely of the material of the spoil-bank. A few 
bones and teeth of ox and sheep or goat were found near the 
level of the quarry floor, but nothing of consequence ; and the 
chief fact ascertained was that the southern chamber terminated 
in a mere joint crevice. As the bottom, however, had not been 
reached, the whole of the material in the chamber was removed 
to a depth of nine feet, where it closed in to a joint ; but 
with little further result. This filling was more stony and
