Besides which, impressions of leaves occur in the " striped sands " 

 (5) at Lewisham, and many plant-remains have been found in the 

 lower part of the plastic clays, &c., at Reading. (See Prestwich, 

 Quart. Jom-n. Geol. Soc. vol. x. p. 88, pi. 4.) These latter have 

 been more lately named by De la Harpe as follows (in the Geol. 

 Survey Memoir, on sheet 10, pp. 113, 116), although perhaps it 

 would be safer, with Dr. Hooker, to leave them without specific 

 names for the present (note to Mr. Prestwich's paper, p. 163) : —

 Laurus Hookeri, Be la Harpe. 

 Kobinia Keadingensis, Be la Harpe,

 Ficus Forbesi, Be la Harpe (ranges 

 up into the Bagshot Beds). 



Prestwichii, Be la Harpe.

 fossils from the basement-bed of the London Clay and the Lower London Ter- 

 tiaries of all parts of England. 



§ 7. On the Outliees oe Sand on the Noeth Downs, which have 



BEEN CLASSED WITH THE CeAG. 



In 1857 Mr. Prestwich read a paper to this Society " On the Age 

 of some Sands, (S:c., on the North Downs," in which he inferred that 

 the beds in question are of Lower Crag age *. The following re- 

 marks on this subject are made with the view, not of giving a
