OSSEOUS BRECCIA OF TWO ERAS. 
149 
edition, has given a list of the animals of this breccia; among which 
he enumerates the os, deer, antelope, sheep, rabbits, water-rats, mice, 
horse, ass, snakes, birds, and land-shells. He states, also, that the 
greater number of them decidedly agree with existing species, and 
supposes them to have fallen into the fissures in the period succeeding 
the last retreat of the waters. With respect to some of these bones, 
it is probable that this hypothesis is correct, and that here, as well as 
in England, there may exist, in addition to the breccia containing 
bones of an tediluvian origin, other more recent deposits, derived from 
animals which are continually falling into the comparatively few 
fissures which are still open, as at Buncombe Park; but with regard 
to others, viz. to those which occur in fissures that are closed up, as 
at Gibraltar, to the very surface of the soil, the case is different, and 
their origin clearly antediluvian. 
In my first paper on Kirkdale I had ventured to differ from M. 
Cuvier on this subject, judging from the apparent agreement in species, 
of many of the graminivorous animals of the osseous breccia with those 
found in the antediluvian cave at Kirkdale, and in the diluvial gravel- 
beds of England, and had suggested that the discovery in the Medi¬ 
terranean breccia of any of the extinct species of animals we find in 
the caves, or in diluvian gravel, would establish the higher antiquity 
I am contending for. Being at Paris in October 1822 , I had the 
satisfaction to be informed by M. Cuvier, that he has lately found 
the tusks of the extinct lion or tiger in the breccia of Nice, and that 
he has added other animals belonging to species now unknown, to 
the list he had before given. Mr. Pentland also has recently dis¬ 
covered the tooth of the same extinct tiger in the breccia of Antibes,
