by Mr. Topley on p. 132 of the Weald Memoir ; this section is still to 

 he seen, and will he mentioned here in its proper place (p. 115). It 

 is evident from Mr. Meyer's remarks in the paper just referred to 

 that he was acquainted with other sections in the hollow lanes of 

 this district, but he gives no details. In the same way, on p. 19 of 

 his 1868 paper ' On the Lower Greensand of Godalming,' printed 

 by the Geologists' Association, he refers, without details, to ' Pebble- 

 beds ' near Dorking, possibly one of the sections described in § II 

 of this paper. From these sections of the Pebble-beds Mr. Meyer 

 places the Fuller's Earth of Nuffield at or near the base of the 

 Folkestone Sands, and almost on the horizon of the Bargate Stone 

 at Godalming. 1 The beds of stone overlying the Fuller's Earth he 

 considers to be the equivalent of the Folkestone Stone-beds ; the 

 coloured sands below the Pebble-beds at Nuffield he calls Sandgate 

 Beds, and certain white sandstone-beds below them, the Hythe 

 Beds. 2 In the various sections given below it will be seen where I 

 differ from his interpretation. 



The Weald Memoir of the Geological Survey, although published 

 in 1875, is (as already stated) based upon F. Drew's notes made 

 about 1860. Full justice is there done to Mr. Meyer's views, 

 but Drew's reading of the beds is adopted : that is, the Fuller's 

 Earth and overlying Stone-beds are described as Sandgate, the iron- 

 sands above the Stone-beds as Folkestone, and the lower beds 

 (described chiefly as sands) Hythe. The division between the so- 

 called Sandgate and Hythe Beds is not stated ; in fact on p. 132, in 

 the description of a section by Mr. Whitaker, that author queries 

 whether the bottom bed of his section belongs to the Hythe, while 

 Mr. Topley immediately afterwards suggests that possibly the two 

 highest beds in a lane just south of Mr. Whitaker's section may 

 belong to the Sandgate. My reason for noticing this is, that it is 

 the same series of sections, referred to above, as those which 

 Mr. Meyer described in 1866, and that gentleman's description is 

 the better of the two. As a matter of fact the ' layers of sand- 

 stone, passing under high road and forming floor of Fuller's 

 Earth pit ' (Folkestone) of Meyer, the ' soft sandstone touched 

 below ' (Hythe ?) of Whitaker, 3 and the ' layers of sandstone ' 

 (possibly Sandgate) of Topley, 3 are a series of sandy chert-beds 

 which everywhere throughout this district (but becoming thicker 

 westward) lie between the main bed of Fuller's Earth and the 

 Pebble-beds — as will be seen later on (pp. 115, 116, etc.). About 

 Tilburstow Hill the Geological Survey places the chert-beds with 

 the Hythe, 4 while I find no mention whatever of the white sand- 

 stones (referred to by Meyer on p. 16 of his paper of 1866 as the 

 highest layers of Kentish Bag). 



Speaking generally, the study of the more recent literature gives 

 the reader the impression that in the Nutfield-Blechingley district 

 the horizons of the Lower Greensand now under discussion consist 

 of a variable series of beds without definite order. My exami- 

 nation of the country does not lead to that conclusion ; on the
