230 GEOLOGY [Ckap. IX 



Letter 563 The importance of his discoveries as they stand before 

 the public fully justify your choice of him ; but what is 

 unpublished, and which I have seen, is, if. possible, still more 

 surprising. Thirty genera of gastcropods (150 species) and 

 150 species of lamellibranchiate bivalves in the Silurian! 

 All obtained by quarries opened solely by him for fossils. 

 A man of very moderate fortune spending nearly all his 

 capital on Geology, and with success. 



E. Forbes' polarity x doctrines are nearly overturned by 

 the unpublished discoveries of Barrande. 



I have called Barrande's new period Cambrian (see 

 Manual, 5th ed.), and you will see why. I could not name * 

 it Protozoic, but had Barrande called it Bohemian, I must 

 have adopted that name. All the French will rejoice if you 

 confer an honour on Barrande. Dana 2 is well worthy of 

 being a foreign member. 



Should you succeed in making Barrande F.R.S., send 

 me word. 



Letter 564 To J. D. Hooker. 



June 5th [1857]. 



The following, which bears on the subject of medals, forms part of 

 the long letter printed in the Life and Letters, II., p. 100. 



I do not quite agree with your estimate of Richardson's 

 merits. Do, I beg you (whenever you quietly see), talk 

 with Lyell on Prestwich : if he agrees with Hopkins, I am 

 silenced ; but as yet I must look at the correlation of the 

 Tertiaries 3 as one of the highest and most frightfully difficult 

 tasks a man could set himself, and excellent work, as 1 

 believe, P. has done. I confess I do not value Hopkins' 

 opinion on such a point. I confess I have never thought, 

 as you show ought to be done, on the future. I quite agree, 

 under all circumstances, with the propriety of Lindley. How 

 strange no new geologists are coming forward ! Are there

3 Prof. Prestwich had published numerous papers dealing with 

 Tertiary Geology before 1857. The contributions referred to are probably 

 those " On the Correlation of the Lower Tertiaries of England with those 

 of France and Belgium," Quart. Journ. Geo/. Soc, Vol. X., 1854, p. 454 ; 

 and "On the Correlation of the Middle Eocene Tertiaries of England, 

 France, and Belgium," ibid., XII., 1856, p. 390.
