 you should happen to be paying a visit to France, let 

 me strongly recommend you to come to Abbeville. I 

 am sure you would be richly rewarded." 6 



This letter aroused the interest of the English geol- 

 ogists, and in the spring of 1859 Prestwich and Mr. 

 (afterwards Sir John) Evans made a visit to, Abbeville 

 to see the specimens and examine at first hand the 

 evidences as pointed out by Dr. Falconer. ''The evi- 

 dence yielded by the valley of the Somme," continues 

 Falconer, in speaking of this visit, ' ' was gone into with 

 the scrupulous care and severe and exhaustive analysis 

 which are characteristic of Mr. Prestwich' s researches. 

 The conclusions to which he was conducted were com- 

 municated to the Royal Society on May 12, 1859, in his 

 celebrated memoir, read on May 26th and published 

 in the Philosophical Transactions of 1 860, which, in ad- 

 dition to researches made in the valley of the Somme, 

 contained an account of similar phenomena presented 

 by the valley of the Waveney, near Hoxne, in Suffolk. 

 Mr. Evans communicated to the Society of Antiquaries 

 a memoir on the character and geological position of 

 the ' Flint Implements in the Drift,' which appeared in 

 the Arch&ologia for 1860. The results arrived at by 

 Mr. Prestwich were expressed as follows : 



" First. That the flint implements are the result of 

 design and the work of man. 



" Second. That they are found in beds of gravel, sand, 

 and clay, which have never been artificially disturbed. 



" Third. That they occur associated with the re- 

 mains of land, fresh -water, and marine testacea, of
