58 ISLE OF WIGHT. [1846-47. 



Buckland, Fitton, De la Beche, Lyell, and others, were 

 his associates. 



Meanwhile Mr and Mrs Russell Scott had moved 

 to Summer Hill, near Bath, where Prestwich on his 

 flying visits made good use of his time in studying the 

 features of that neighbourhood. 



The geology of the northern portions of the Isle of 

 Wight had a special attraction for him, and year after 

 year repeated visits were made by him to unravel 

 the structure of the district. In 1846 he read a 

 paper at the Geological Society, " On the Tertiary or 

 Supracretaceous Formations of the Isle of Wight, as 

 exhibited in the Sections at Alum Bay and White 

 Cliff Bay." In this he showed more certainly than 

 had been done before that the elevation of the chalk 

 ridge was subsequent to the deposition of the Headon 

 Hill series, and he pointed out the connection between 

 the lower Eocene beds and those of Bognor. In 

 the same year he wrote a joint paper with his old 

 friend Professor John Morris, " On the Wealden Strata 

 exposed by the Tunbridge Wells Kail way." Both of 

 these papers appeared in the Geological Society's 

 Journal, vol. ii., 1846. He also gave a notice to the 

 British Association Meeting at Southampton that year, 

 " On the Occurrence of Cypris in a part of the Tertiary 

 Freshwater Strata of the Isle of Wight." 



Early in 1847, the Palseontographical Society had 

 its rise, Joseph Prestwich having been one of its 

 original members. From Dr H. Woodward's 1 inter- 

 esting account of its foundation and progress we 

 quote the following passages : 



The origin was mainly due to the prior issue of Sowerby's
