DISCOVERED AT KIRKDALE.

sand and gravel from the Kirkdale Cavern, could be no 
valid objection to my hypothesis ; for, in the bottom of the 
diluvian ocean, as in that of the present ocean, there might 
be spots where mud alone prevailed, as well as others where 
sand and gravel predominated. 
The subject might admit of additional illustration, but 
I shall only notice farther, a fact, observed by Professor 
Buckland, viz. that the bases of the stag's horns found in 
the Cave at Kirkdale, appear to indicate diat they have 
been shed from the head, and not broken off by violence ; 
a fact which, according to the hypothesis advanced in this 
paper, may be deemed curious, as serving to point out the 
season of the year when the Mosaic Deluge commenced.* 
• Since this and the former paper (published in vol. iv.) were com- 
municated to the Society, the author has seen good reason to exclude 
the horse from the list of the animals whose remains have, been pre- 
served in Kirkdale Cave. All the remains of this animal, extracted 
from the Cave, appear to have been thrown into it by some wags, or 
rogues, on purpose to increase the amount of the relics. The teeth of 
sheep and of hogs, as well as those of horses, have thus found their 
way into collections of Kirkdale bones. A horse tooth, selected from 
such spurious relics, has the honour of being figured in one of Profes- 
sor Buckland's plates. 
The specimen of jaw-bone with two teeth, noticed in vol. iv. p. 263, 
as not identified, and of which a model was presented to the Wernerian 
Society, appears to belong to a small hippopotamus. The grinders of 
that animal are usually marked with rosettes on their masticating sur- 
face, and some teeth so marked were found in the cavern ; but when 
the surface is worn down, the grinders correspond exactly with the two 
teeth in that specimen.
