intersecting one another at right angles. Numerous bones of Rhino- 

 ceros tichorhinus, Bos, Equips, Cervus tarandus, Ursus spelatus, and 

 H'jama have been found; and several flint-implements have been 

 met with in the cave-earth and gravel beneath. One in particular 

 was met with immediately beneath a fine antler of a Reindeer and 

 a bone of the Cave-bear, which were imbedded in the superficial 

 stalaa-mite in the middle of the cave.

 of Drift-Gravel and Brick -earth at St. Achetil, near Amiens.

The implement or weapon which I desire to bring under the notice of 

 this Society, and a drawing of which accompanies these observations 

 (PL XL), was found by me about a month since, when, in company 

 with Mr. Prestwieh and other Fellows of this Society, I visited some 

 gravel-pits near Amiens. When discovered, it was imbedded in a 

 compact mass of gravel, composed of large chalk-flints much water- 

 worn and rolled, and small chalk-pebbles. It was found lying at the 

 depth of sixteen feet from the upper surface, and about eighteen inches 

 from the face or outer surface of the quarry, to which extent the gravel 

 had been removed by me before I found it. The bed of gravel in ques- . 

 tion forms the capping or summit of a slight elevation of the chalk. A 

 section of this pit, which Mr. Prestwieh lately exhibited to the Royal 

 Society*, showed that the gravel presents here a thickness of about 

 ten feet. Above this occurs a thin bed of coarse, white, siliceous 

 sand, interspersed with small rounded chalk-pebbles ; and above the 

 sand is a layer of strong loam, of a red colour, which is now exten- 

 sively worked for the purpose of making bricks. The remains of the 

 Elephant, Horse, and Deer have been occasionally found in the gravel ; 

 and we found in the sand which rests upon it an abundance of land 

 and freshwater shells, all of recent species. No fossils of any kind 

 were discovered by us in the brick-earth tying on the surface. At 

 the distance of a few hundred yards from the convent of St. Acheul 

 are the remains of an ancient Roman cemetery. A large stone tomb 

 is here left standing on the surface, the brick-earth having been 

 cleared away from it; and here many Roman coins and bronze 

 ornaments are found. 



At St. Roch (about half a mile distant from St. Acheul), we also 

 examined a quarry of flint-gravel, of precisely the same character, 

 and, apparently, of the same period as that of St. Acheul. We pro- 

 cured from it two very fine tusks of the Hippopotamus, which had
