FLINT IMPLEMENTS FOUND IN KENT'S CAVERN. 349 
form two inclined planes dipping towards one another; the Cave- 
earth at a high gradient, and the Breccia at a low one. 
Excepting the overlying blocks of limestone, (No. 1,) which 
need not be mentioned again, all the deposits contained remains 
of animals. In the Black Mould, the most modern accumulation, 
they were those of species still existing, and almost all of them 
now occuping the district; namely, Man, Dog, Fox, Badger, Brown 
bear, Los longifrons, Roe-deer, Sheep, Goat, Pig, Hare, Rabbit, 
Water-rat, and Seal. 
The Cave-earth may be termed the great mausoleum of the 
Cavern, in which recent and extinct species were commingled. 
As the remains found in the Black Band, which may be said to 
form part of it, and in the overlying Granular Stalagmite, belonged 
to species all represented in the Cave-earth but not in the overlying 
Black Mould, the three deposits may be regarded as belonging to 
one and the same biological era. The following is a list of the 
species they have yielded :—The Cave hyzna was by far the most 
prevalent form, and his presence was attested, not only by his 
numerous teeth and bones, but by his coprolites, by bones broken in 
a manner still followed by existing members of the same genus, and 
by the marks of his teeth on a very large portion of the osseous 
remains, including those of his own kith and kin. The next most 
prevalent forms were the Horse and Rhinoceros. Remains of the 
Gigantic Irish Deer, Wild Bull, Bison, Red Deer, Mammoth, Badger, 
Cave Bear, Grizzly Bear, and Brown Bear were by no means rare ; 
those of the Cave Lion, Wolf, Fox, and Reindeer were less nume- 
rous; and those of Beaver, Glutton, Machairodus latidens, and Man 
were very scarce. So far as is at present known, the presence of 
the Glutton is attested by a single os innominatum; Machairodus 
latidens, by five canines and two incisors; and Man, by a portion 
of upper jaw containing four teeth, which together with a solitary 
tooth was found at the base of the Granular Stalagmite, where it 
was 20 inches thick. 
In the lowest deposits—the Crystalline Stalagmite and the 
Breccia—remains of animals were less uniformly distributed. In 
some instances there were none throughout considerable volumes of 
the deposits, whilst in others they formed 50 per cent. of the entire 
accumulation. For a considerable period relics of bears were alone 
found, but recently two “‘finds” of feline teeth, probably Felis spelea,
