In chronology, all that is proved by these discoveries of M. Lartet is
that the fossil animals mentioned above and man were contemporaries on
the earth. The age of each must be determined inferentially by comparing
the age of strata in which these animals are usually found with the age
in which the most ancient traces of man are discovered,--such as the
deposits already described in the North of France.

Similar discoveries on a smaller scale are recorded by Mr. Prestwich
in Suffolk, England, and in Devonshire. We are informed also by Sir C.
Lyell of a recent important discovery near Troyes, France. In the Grotto
d'Arcès, a human jaw-bone and teeth have been found imbedded with
_Elephas primigenius_, _Ursus spelaeus_, _Hyaena spelaea_, and other
extinct animals, under layers of stalagmite. Professor Pictet, the
celebrated geologist, who also gives his adhesion to these discoveries
of M. de Perthes, states that the cave-evidence has by no means been
sufficiently valued by geologists, and that there are caverns in Belgium
where the existence of human remains cannot be satisfactorily explained
on the theory of a modern introduction of them. The President of the
British Association (Lord Wrottesley) also states that in the cave of
Brixham, Devonshire, and in another near Palermo, in Sicily, flint
implements were observed by Dr. Falconer, in such a manner as to lead
him to infer that man must have coexisted with several lost species of
quadrupeds.

Professor Owen, in his "Palaeontology," (1861,) appears to put faith in
the genuineness and antiquity of these flint relics. He also states that
similar flint weapons have been found by Mr. John Frere, F.R.S., in
Suffolk, in a bed of flint gravel, sixteen feet below the surface, of
the same geological age as that in the valley of the Somme.
