EXPLANATION OF THE PLATES. 
277 
distinctly visible at a, b, c, d, e, f. See note at p. 37, describing the 
hyaena’s manner of breaking and partly devouring this bone. N os. 1, 
2, 3, and 4, are reduced one-third. 
2. Fragment of a similar tibia from Kirkdale Cave, broken nearly 
in the same manner as No. 1, and bearing similar marks of teeth at 
a, b, c, d, e : in the recent, as in the antediluvian specimen, the lower 
condyle has, from its hardness, been left unbroken. 
3. Splinter from another bone broken by the hyaena at Oxford: 
the cavity at A. was produced by the hyaena’s tooth. 
4. Similar splinter, bearing a similar cavity A., from the cave at 
Kirkdale, and partially incrusted with stalagmite. 
5. Inside view of the lower extremity of the recent specimen, 
No. 1, in which the hole A. was produced by the hyaena’s bite. Nos. 
5 and 6 are reduced nearly one-half. 
6. Lower extremity of another tibia from Kirkdale, in which the 
form of the cavity A. resembles that in No. 5. 
7. Scaphoid bone of the left carpus of an ox, which, with the 
other component bones of the carpus, lay all night untouched in the 
hyaena’s cage at Oxford. 
8. Similar bone from Kirkdale, equally untouched. 
The above specimens go far to explain the fact of the abundance 
(in excess) at Kirkdale of similar solid and marrowless bones, and frag¬ 
ments of bone; and of the absence of the softer portions analogous to 
those which were devoured by the hyaena in Oxford. 
9. Fragment of the lower jaw of a young hyaena from Plymouth, 
exhibiting the posterior molar tooth of the first set about to be shed, 
and two of the permanent teeth rising in the jaw beneath ; from a 
drawing by Mr. Clift. 
10. Jaw of a young hyaena from Kirkdale, belonging to Mr. Sal- 
mond, showing it to have but three deciduous molar teeth in the
