Additions to a Paper in the last Number of the Annals of Phi- 

 losophy. By William Henry Fitton, MD. FRS. MGS. &c. 



(To the Editors of the Annals of Philosophy .) 

 GENTLEMEN, 20rt November, 1824. 



I shall be much obliged by your inserting the following 

 paragraphs connected with my paper in the Annals of' Philoso- 

 phy for the present month, if possible, in the ensuing number of 

 your journal, that they may be placed in the same volume with 

 the paper to which they refer. 



I remain, Gentlemen, your obedient humble servant, 



William Henry Fitton. 



I had stated in a memoir read at the Geological Society during 

 the last Session,* before I had examined the Isle of Wight, that 

 I was indebted to Mr. Lyell, one of the Secretaries of that body, 

 for complete evidence of the identity of the greenish beds below 

 the chalk between Beachy Head and Sea-Houses, in Sussex, 

 with what I have denominated Firestone, at Culver in the Isle 

 of Wight ; and in your last number (p. 381), I have men- 

 tioned my obligation to the same gentleman for a section of 

 the beds below the chalk at Shiere, near Guildford, in Surrey. 

 I was not then aware, nor was 1 till Mr. Lyell's return to London 

 during the last week, fully informed upon this subject, that his 

 observations in the Isle of Wight were more extensive than 

 I at first supposed ; since he had not only found at Sandown 

 Bay the calcareous nodules inclosing univalves, which I have 

 mentioned (p. 374), but had deduced from his observations the 

 same inferences respecting the real order of the strata below the 

 chalk, and their correspondence in the Isle of Wight with those 

 of Kent and Sussex, as I have been led to, by considering the 

 features of the surface, and by subsequent examination of the 

 strata. Mr. Lyell's observations were communicated by letter to 

 Mr. Mantell, of Lewes, so far back as in July 1822 ; and during 

 a tour in the Isle of Wight in the spring of 1823, with the Hon. 

 H. G. Bennett and Prof. Buckland, Mr. Lyell pointed out upon 

 the spot to those gentlemen the facts on which his views were 

 founded : which, as they accord with most of the essential 

 points that I have mentioned, would no doubt, if followed up, 

 have led to the same results. — Had I been informed, as I am 

 at present, of these circumstances, I should unquestionably have 

 mentioned them in my paper; and I now think it is due, both
