Bones discovered in a cave at Kirkdale, in Yorkshire. 1 85 
weasel. (Plate XX. fig. 28, 29.) Teeth of the larger pachy- 
dermatous animals are not abundant. I have information of 
about ten elephants’ teeth, but of no tusk ; and as very few 
of these teeth exceed three inches in their longest diameter, 
they must have belonged to very young animals. (See Plate 
XXI. fig. 1 and 2). I have seen but six molar teeth of the 
hippopotamus, and a few fragments of its canine and incisor 
teeth ; some of which latter are in the possession of Mr. 
Thorpe, of York. Teeth of the rhinoceros are not so rare. 
I have seen 40 or 50, and some of them extremely large ones, 
and apparently from aged animals. I have heard of only 
two or three teeth belonging to the horse. Of the teeth of deer 
there are at least three species (see Plate XXII. fig. 9,1 1 ,13), the 
smallest being very nearly of the size and form of those of a 
fallow deer, the largest agreeing in size, but differing in form 
from those of the modern elk ; and a third being of an inter- 
mediate size, and approaching that of a large stag or red 
deer. I have not ascertained how many species there are of 
ox, but apparently there are at least two. But the teeth which 
occur perhaps in greatest abundance, are those of the water- 
rat (see PI. XXV. fig. 1 to 5, and 1 1 to 18 ;) for in almost every 
specimen I have collected or seen of the osseous breccia, there 
are teeth or broken fragments of the bones of this little 
animal mixed with and adhering to the fragments of all the 
larger bones. These rats may be supposed to have abounded 
on the edge of the lake, which I have shown probably to have 
existed at that time in this neighbourhood : there are also a 
few teeth and bones of rabbits and mice. (Plate XXIV. 
fig. 14, 15, 16, 17, 18, and Plate XXV. fig. 7,8,9, 10).
