interstratified with the gravel, at a depth of about 4 feet from the 

 surface. He took it away and preserved it in his collection as an 

 object of antiquarian rather than of geological interest. Hearing, 

 however, of the late discoveries at Amiens and Hoxne, he sent the 

 specimen, with an account of his finding it, to Mr. Evans. It is an 

 undoubted flint implement, rude and of a peculiar wedge-shaped 

 form. I have one specimen from St. Acheul with which it closely 

 agrees. This of course can be considered but as a possible instance. 



Hertfordshire. — It is only ten days since Mr. Evans, while walk- 

 ing with some antiquarian friends from Nash Mills to Abbots 

 Langley, was struck with the great number of quartz, siliceous sand- 

 stone, slate, and other old rock-pebbles and fragments scattered over 

 a field near the latter place, and was still more surprised at finding, 

 among this surface- drift, a weathered flint implement with the top 

 broken off, but otherwise identical in form with the spear-head- 

 shaped specimens from Amiens and Herne Bay. Although found on 

 the surface, Mr. Evans, who is most competent authority on this point, 

 does not consider it to belong to the Stone-period. On the contrary, 

 he would refer it to the Pleistocene age. I have been with him to the 

 spot where it was found. The chalk hills are here about 200 feet above 

 the level of the Boxmoor valley, and are in places bare, and in other 

 places thinly covered with gravelly drift. Between this peculiar drift 

 and the flint implement I myself saw no connexion, and I can merely 

 mention the fact without venturing to speculate upon it. 



We have thus, at all events, three additional counties in which Post- 

 pliocene flint implements have been found ; and I would now direct 

 attention to a few other localities where there are beds of fresh- 

 water gravel and sand, or of freshwater and other associated gravels, 

 in which I think it highly probable that flint implements may occur. 



Places for further Search. — I woidd more especially direct attention 

 to the gravel- and clay-pits at Copford, Lexdennear Colchester,, and 

 Sudbury; the brick-pits at Erith, Grays, Ilford, Maidstone, and Salis- 

 bury ; the low-level gravel-beds at or near Alton, Axminster, Bath, 

 Blandford, Brentford, Cambridge, Chartham, Chesterford, Chichester, 

 Chippenham, Croydon, Defford, Dover, Farnham, Faversham, Eolk- 

 stone, Gloucester, Godahning, Hackney, Hertford, Hurley, Kingsland, 

 Oxford, Peasemarsh, Beading, Selsea, Stafford, Stamford, Stroud, 

 Taplow, Wandsworth, Westbury, Worcester, and Orton near Peter- 

 borough, as some of the places in the south of England where, I think, 

 flint implements ma} r also, by diligent search, possibly be found. I say 

 " diligent," because even in places where they are most abundant, 

 as at St. Acheul, the search must be long before the observer is 

 rewarded by finding a single specimen ; whilst in other places the 

 search often seems for a time almost hopeless. Judging from pre- 

 cedents, our motto should be Nil desperandum.
