5. The Neocomian, Greensands, Wealden, Portland Beds, and 



Kimmeridge in the Pays de Bray. 



6. Le Chateau de Gisors. Thence across to Compiegne, where 



you have 



(1) A very rich locality for the shells, " Lits Coquilliers," in 



a small valley just beyond Pierrefonds. 



(2) The fine Chateau de Pierrefonds. Again, on the main 



line, just above Anvers or Angers, there is on the right 

 bank of the Oise, near the top of the hill, a site noted 

 for its Quaternary mammalian remains. 



With kind regards to all who may be with you, and wishing 

 you well through and soon out of this weather, I am sincerely 

 yours, J. PRESTWICH. 



Eemember me to MM. Pinsard and Gamier if you see them. 

 My wife sympathises more with Mrs Evans than with you I 

 don't. 



In March a review appeared from his pen in ' Nature ' 

 on the magnificent work of his old friend M. Belgrand, 

 on ' La Seine : le Bassin Parisien aux Ages ante- 

 historiques.' 



A very pleasant friendship which he made while on 

 the Royal Coal Commission was with its secretary, Mr 

 J. F. Campbell, the accomplished author of ' Frost and 

 Fire.' 



J. F. Campbell to J. Prestwich. 



ISTiDDRY LODGE, KENSINGTON, 8th May 1872. 



DEAR PRESTWICH, I have not had the grace to thank you for 

 your Address, but I have been much obliged and instructed 

 thereby. When you happen to be in these regions come and 

 geologise in my garden. It is on the Clay under the Gravel, well 

 on the top of which some Company has made waterworks and a 

 tower. You will easily find your way by the tower, and if the 

 waterworks burst, you will return to the Thames faster than you 

 came up this hill. I am, yours very truly, J. F. CAMPBELL.
