No human bones have as yet been discovered in the deposit of the Somme valley, where so many Palæolithic flints have been found; but in the valley of the Seine, at Clichy, Messrs. Bertrand and Reboux found, in 1868, portions of human skeletons in the same beds where Palæolithic implements had been embedded. These bones were found at a depth of seventeen feet, and included a female skull of very inferior type, having enormously thick frontal bone and a low, narrow roof, slanting from before backwards. A very good specimen of human fossil is that known as the “Denise Fossil Man,” comprising the remains of more than one skeleton found in a volcanic breccia near Le Puy-en-Velay, in Central France. These bones have been very carefully examined by the members of the French Scientific Congress, as also the deposit in which they were found, and the opinion arrived at is that the fossils are genuine and their age early Pleistocene. Another most interesting specimen of ancient human remains is the skeleton found buried under four Cypress forests, superimposed one upon the other, in the delta of the Mississippi, near New Orleans, at a depth of sixteen feet. Dr. Dowler ascribes to this skeleton an antiquity of at least 50,000 years, reckoning by the minimum length of time that must have elapsed during the formation of the deposits found and the sinking of the four successive forest beds. In another part of the same delta, near Natchez, a human bone, _os innominatum_, accompanied by bones of the mastodon and megalonyx, was washed out of what is believed to be a still more ancient alluvial deposit. Dr. Dickeson, in whose possession the said bone is now, states that it was buried at a depth of thirty feet, and geologists agree that its date is very early, some maintaining that it is probably of a higher antiquity than any yet discovered.
