374 ON THE CO-EXISTENCE OF MAN 
I may add to what I have stated above, that the finding of worked 
flints in the diluvium of Amiens and Abbeville is by no means an 
isolated fact. M. Gosse of Geneva, a young medical student in 
Paris, has recently discovered in the sands of the Parisiay, suburb of 
Grenelle, of the same age as those of Abbeville and of other parts 
of Europe, a flint hatchet of a most distinct form, together with 
knives or thin plates split in a longitudinal direction. I myself have 
had an opportunity of verifying these facts in the collection formed 
by that skilful explorer. He has shown me an. Elephant’s tooth, a 
canine tooth of a large Feline animal, and bones of the Aurochs, 
Horse, &c., all obtained from the same sands and from the same bed 
in which the flint hatchet was found. . 
I may add that, among the bones obtained in Switzerland under 
the lacustrine habitations of the Stone Period (in the lakes of Moos- 
dorf, Bienne, aud others), there never have been found any remains 
of the Megaceros, although the remains of the Elk, the Aurochs, and 
the Bos primigenius are by uo means rare. In Denmark, where 
still more ancient stations have been carefully examined with the 
same object, Prof. Steenstrup has assured me that he has never 
discovered the smallest fragment of the Megaceros in the midst of 
the most abundant remains of the Reindeer, Elk, Aurochs, and other 
species of animals which from time immemorial have not existed in 
that region. Nevertheless these primitive stations in Denmark are 
referred back to a period when no other domestic animal existed in 
that country except the Dog. No remains have been found either 
of the Horse, Sheep, or Goat,—not even any kind of dwarf Ox. 
If, Sir, you are of the opinion that the above notes, drawn up in 
haste, are likely to prove interesting to the Geological Society of 
London, I should be happy if you would submit them to the enlight- 
ened judgment of your learned associates, and if they will receive 
them at the same time as a mark of my deference, and as a feeble 
expression of the profound gratitude I feel for the honour conferred 
upon me by my name having been inscribed among the Foreign 
Members of that Society. -

friend M. Delesse having shown me some fragment of bone bearing
