JET. 43-44.] TREASURER OF GEOLOGICAL SOCIETY. 99 



deeply I regret he is not amongst us to continue the inquiry 

 and description with us. 



The following note, also to Sir Charles Lyell, gives a 

 little glimpse of Prestwich's life in Mark Lane : 



MARK LANE, Monday, 1855. 



MY DEAR SIR CHARLES, I am not surprised that you com- 

 plained of the exchanged coat. You have the best reason for 

 doing so. On returning home this morning a red label on a coat 

 on the sofa caught my eye. My housekeeper sometimes places 

 there an old coat of mine that I use to read or work in. This is 

 missing. When here on Thursday you must have placed yours 

 on or by mine on the sofa, and in going away have taken up the 

 wrong coat. I am glad to find that the exchange was made here 

 and not in the railway carriage. ... I hasten to return your 

 coat, which I hope you have not wanted, and remain yours very 

 truly, J. PRESTWICH. 



P.S. I walked yesterday through a good cutting of the Lower 

 Bagshot at Stroud Green and one good one of the Middle (Green- 

 sand) Bagshot at King's Beeches. I found no fossils, but traced 

 the Wealden gravel over some extent of the ground. I have 

 found the same gravel, but not quite so mixed with L. G. S., at 

 Hazely near Strathfieldsaye. 



In 1855 Prestwich was elected as one of the Secre- 

 taries of the Geological Society, Mr J. Carrick Moore 

 being the other Secretary. This honorary post he 

 occupied only one year, as in 1856 he became Treasurer 

 of the Society, an office which he held until 1868. In 

 this year he read his second correlation paper, " On 

 the Correlation of the [Middle] Eocene Tertiaries of 

 England, France, and Belgium." This was published 

 in 1857. 



The following letter from Sir Charles Lyell refers to 

 this paper, and especially to the list it contains of those 

 Bracklesham shells which occur also in the Paris
