JET. 45.] MR JOHN EVANS. 105 



could not be done in France the evidence is wanting. At 

 Kichborough the one distinctly overlies the other. See my first 

 paper on the " Correlation of the French and English Tertiaries." 

 There are a few species in common, but the bulk are different. 

 In haste, ever truly yours, J. PRESTWICH. 



Before the date of the annexed note Joseph Prest- 

 wich made the acquaintance in the railway carriage 

 of a fellow-traveller who had likewise been summoned 

 as a witness, though on the opposite side, of a cause 

 set down for trial at the Kingston Assizes with regard 

 to a water question at Croydon. They had travelled 

 to Kingston in the same carriage without interchange 

 of a word ; but, as for some reason the trial did not 

 come off that day, they found themselves in the after- 

 noon again in the same railway carriage, when they 

 entered into conversation and found that they had 

 many interests in common. This was our geologist's 

 first meeting with Mr John Evans of Nash Mills, 

 Hemel Hempstead, who in a letter to the writer re- 

 marks : "I took a great liking for him, and I think 

 that he did not dislike me, and the result was that 

 I called on him in Mark Lane and he returned the 

 visit at Nash Mills, and thus began a friendship which 

 lasted forty years, and which most materially influ- 

 enced the course of my life. I cannot at present call 

 to mind the exact year of our meeting, but our friend- 

 ship was already of some standing when in 1857 he 

 introduced me to the Geological Society." Much 

 pleasant field-work was afterwards accomplished by 

 the two friends, and when they differed on geological 

 questions as differ they did it never caused the 

 slightest abatement nor estrangement of the brotherly 

 affection which had grown up between them, and which 

 was ever the same to the end.
