MT. 42-43.] VALLEY GRAVELS. 97 



It had been preceded by two papers of relatively 

 less importance, namely, by that " On a Fossiliferous 

 Deposit in the Gravel at West Hackney," and " On 

 a Fossiliferous Bed of the Drift Period near the 

 Reculvers." The two which followed it were, " On the 

 Boring through the Chalk at Kentish Town," and a 

 " Note on the Gravel near Maidenhead, in which the 

 Skull of the Musk Buffalo was found." These were 

 both read in 1855, and appeared in the Geological 

 Society's Journal in 1856. 



Reference is made to the last paper in the following 

 letter to Mr Lubbock, 1 who subsequently was his com- 

 panion in several excursions : 



MARK LANE, 10/7/55. 



MY DEAR SIR, I am rejoiced to hear of the discovery of the 

 musk-ox in the Maidenhead gravel. . . . There are several other 

 large pits in the valley gravel which may be worth examining. 

 Could you also inquire whether any bones were found in the 

 gravel cutting of the Wycombe Railway at the hill (Folly Hill) 

 adjoining Maidenhead ? I inquired, but was not quite satisfied with 

 the answer I obtained, although it was in the negative and agreed 

 with my general views on the subject. On Saturday last instead 

 of going to Staines I went to Brentwood and Warley. I shall 

 most probably therefore go to Staines on Saturday next, and in 

 that case shall require the map which I herewith send. If you 

 will let me have it on Friday evening or Saturday morning 

 before 12, it will do. Sir C. Lyell and I went to Grays last 

 week, but shall have to return to Ilford probably on Friday or 

 Monday next. We shall not remain long at the pits, but would 

 show them to you, and possibly, if you could accompany us, 

 might have to leave you there, as I fear there might not be room 

 in the carriage of Mr Meeson, who proposes to take us to some 

 other pits in the neighbourhood. The Grays pits are, however, 

 the great features, and these I shall be happy to show you, and 

 to join you again there. Believe me to remain, yours very truly.
