paper, and I do not now see what time I can get except my old 

 plan of Saturday night to Monday, and making each a separate 

 excursion. I must also try for two days at Amiens. 



I shall be glad and curious to hear what you saw and what 

 you did at Icklingham. Can you give me a few lines by the 

 morning's post, or have you not been there, and will you go ? 



September 1 5th was the date of this visit to Bedford ; 

 on the 19th he was at Herne Bay, and on the 26th at

 a flint implement of the St Acheul type worn, but not 

 stained." 



During the spring, one of the Friday- evening lectures 

 was given by Prestwich at the Boyal Institution, its 

 subject being, "On the Quaternary Flint Implements 

 of Abbeville, Amiens, Hoxne, &c. : their Geological Posi-
