“ remote antiquity of those industrial objects, and their associa- 
* tion with animals now extinct.” 
“Acting on Dr Falconer’s suggestion, Mr Prestwich, F.R.S., 
‘‘ whose researches have been so extensive and accurate as to 
“place him in the first rank of English geologists, in April, 
“©1859, visited Abbeville and Amiens, where I, on his invitation, 
“had the good fortune to join him. We examined the local 
“collections of flint implements, and the beds in which they 
“were said to have been found; and in addition to being 
“ perfectly satisfied with the evidence adduced as to the nature 
“‘ of the discoveries, we had the crowning satisfaction of seeing 
“one of the worked flints still in situ, in its undisturbed matrix 
“of gravel, at a depth of 17 feet from the original surface of 
“the ground. 
“From the day when Mr Prestwich gave an account to the 
** Royal Society of the results of his visit to the Valley of the 
“Somme, the authenticity of the discoveries of M. Boucher de 
“Perthes and Dr Rigollot was established; and they were 
“almost immediately followed by numerous others of the same 
“character both in France and England. In this country, 
“indeed, it turned out, on examination, that more than one 
‘such discovery had already been recorded, and that flint 
“implements of similar types to those of Abbeville and Amiens 
“had been found in the gravels of London at the close of the 
“17th century, and in the brick earth of Hoxne, in Suffolk, at 
“the close of the 18th century, and were still preserved in the 
“ British Museum and that of the Society of Antiquaries.”’ 
These implements are now met with in Middlesex, Berks, 
Bucks, Bedford, Herts, Northampton, Essex, Suffolk, Norfolk, 
Sussex, Surrey, Hants, the Isle of Wight, Dorset, Somerset, 
Wilts, Oxford, Cambridge, and Kent. In May, 1881, Mr J. E. 
Greenhill found at Stoke Newington, and almost close to Hack- 
ney Brook, two long pointed implements; and subsequently Mr 
Worthington G. Smith has met with, in the neighbourhood of 
London, and particularly at Stoke Newington, what he terms a 
Paleolithic floor [Memoirs of the Geological Survey of England 
and Wales, by W. Whitaker, Vol. I. Hd. ii. 1889, pp. 350, 351,
