important respects the osseous contents of this fissure haye a 
markedly individual character. 
Thus among the earliest finds were those of teeth and fragments 
of bones of the rhinoceros—of one animal only—and discovered, 
though at intervals extending over three months, scattered through 
the fissure-earth in tolerably close proximity. Next came the bear, 
again a single individual, but much more largely represented, the 
osseous fragments representing nearly every part of the skeleton. 
So with the horse, the hyzna, wolf, fox, and boar—each also 
represented by single individuals, or if by more than one, by 
remains so curiously individualized as to include no duplicates, 
unless in the case of the boar, and the wolf—there is a doubt 
whether some of the teeth referred to the latter may not be those 
of a species of dog. 
To a large extent the same appears to be true of the cervine 
remains ; for while these indicate the occurrence of several deer, 
they show also the presence of differing species, though in the 
most important particular of all there was certainly at least a 
double representation. 
The only genus which is at all widely represented is the bovine. 
More than a hundred bovine teeth of various ages and species, 
young and old, were found, but very few bones to match. Some 
of the teeth evidently belong to very young animals, and others to 
very aged; and Bos primigenius, and longifrons, and probably 
Bison priscus, are indicated. 
With very few exceptions, the bones and teeth were simply 
scattered through the earth, and in no great quantity at any one 
spot, though retaining in many cases the special association indi- 
cated. A few, however, which had found their way into the side 
chambers, were partially encrusted with stalagmite ; and there were 
also found one or two masses of stalagmite enclosing bones of 
considerable size, indicating the introduction of the bones in ques- 
tion into the cavity while the stalagmite was in process of formation 
(with or without their integuments), independently of such ex- 
traneous matters as earth or clay. 
The association of the remains is of such an accidental character, 
and yet bears such a relation to the general fauna of the country 
at the date of the deposit, that there seems little difficulty in 
accounting either for their presence, or for the condition in which 
they were found. We have here evidently a tunnel cavern, eroded
