^T. 39-40.] GEOLOGICAL PAPERS. 87 



for 1852, thus appearing two years in advance of the 

 second part. Its title was, " On the Structure of the 

 Strata between the London Clay and the Chalk in the 

 London and Hampshire Tertiary Systems. Part III., 

 The Thanet Sands." 



The entry in the note-book for this year is : " Easter 

 Excursion, 6th to 15th April 1852. Forbes, Austen, 

 Morris, and myself started on Tuesday for Boulogne. 

 D. Sharpe and Tylor joined us at Calais on Wednesday 

 night." They were met at Tournay by M. Dumont 

 and M. Lambert, who were their guides over the most 

 interesting ground in the vicinity of Mons, Liege, 

 Aix, &c. 



Another letter to Mrs Russell Scott mentions the 

 amount of time spent on two geological papers : 



LONDON, 22nd December 1852. 



MY DEAREST ISABELLA, Notwithstanding the troubles I have 

 gone through, I am happy to say that my views and feelings 

 continue as fresh as ever. I have no feelings of disappointment, 

 and an abundance of hope. As contributing to this desirable 

 end, I find geology is a most important adjunct. You must not, 

 however, judge of the amount of labour (one, by the bye, of love, 

 and therefore not felt as a burden but as an enjoyment) by the 

 size of the results. The paper on the Thanet Sands is part of 

 the results of ten to twelve years' researches that on the Holm- 

 firth Flood is the result of one Sunday's walk on a fine day last 

 February. You are very good to read my papers. I do not 

 expect it. You form an honourable exception to the rest of the 

 family. My poor mother used to be the only member of it who 

 ever had the patience to get through them. 



I shall be delighted to see the children in town. Kate and 

 her children are coming up to-morrow. With my best love to 

 all the absentees, and wishing them all a happy and merry Christ- 

 mas, I remain, ever your affectionate brother, 



J. PRESTWICH, Jun.
