It will be here right to observe that it is more than doubtful 
whether the remains from caverns should be considered as of 
one age. The Machairodus, or great British tiger, is not 
believed to have lived down to the Post- Pliocene age, and yet its 
remains are found mingled with Post-Pliocene Mammalia in 
Kent’s Hole and other caverns. 
It may be that many of the caves and fissures containing 
osseous breccia, mammal, and other bones, were open during 
the Miocene age ; and if one considers how long bones 
might remain under such circumstances uncovered by any 
preserving’ or time-separating deposits of mineral matter, it is 
easy to conceive how, by the tread of wild beasts, the irregular 
falling together of the bones themselves, as their muscles and 
ligaments decomposed, and by various other natural causes, a 
commingling in cave-accumulations of the relics of widely 
distant epochs could, and doubtless did, take place. 
Alluvial deposits are, of course, the link between the past 
and present. As yet, however, they have been little worked, 
for the relics of this border-land between past and present time 
have not found much favour in the eyes of the geologist, and as 
little in those of the archaeologist or naturalist. 
The remains of dodo (Diclus ineptus), solitaire (Pezophaps 
solitaria), two species of the singular wingless apteryx, ten 
or more species of the gigantic dinornis of New Zealand — 
some standing ten feet high, and some with three-toed feet 
twelve or fifteen inches long, three apteryx-likebirds ( Palapteryx 
ginens, P. dromioides, P. geranoides) , aptornis (Aptornis) , and
