I cannot close these pages without expressing my hope that the 

 history of the Kentish Limestone, including the catalogue of its fos- 

 sils, may he extended and published without delay. This deposit, 

 we now know, is the Calcaire a Spatangus of foreign geologists, and 

 probably exhibits that portion of the Terrain Neocomien as distinctly 

 as most of the continental types, — ^with this important advantage, 

 that its connexion with the adjoining groups, both above it and below, 

 is here distinctly seen. When I call to mind the number of good 

 collections from this tract already existing, but now detached, and 

 the zeal and intelligence of the proprietors, I cannot doubt that co- 

 operation only is required to produce a most valuable catalogue of the 

 fossils. Mr. Hills, formerly of Court-at-street near Hythe, and now 

 connected vdth the Institution at Chichester, has long since distin- 

 guished himself by the discovery of new species in the former vicinity. 

 Mr. Bensted of Maidstone and Mr. Mackeson of Hythe are well- 

 known for their zeal and success as geological inquirers ; and Mrs. 

 Smith of Tunbridge "Wells is possessed of a cabinet full of rare and 

 interesting fossils. From these four persons only, — and there must 

 be many more, — I am convinced that materials for an excellent list of 

 Kentish fossils could be obtained, if a well-arranged plan for their 

 publication were set on foot ; and in the meantime, it must be recol- 

 lected, the history of our Enghsh strata below the chalk is in- 

 complete.
