Remarks on the Ancient Flora of the Ecvrth. 119 



in bis work on Organic Remains. W. Phillips also mentions, 

 in the marl belonging to the chalk formation of Folkestone, (G. 

 Tr. vol. i. pp. 49, 50), wood-coal, still possessing the fibrous tex- 

 ture of wood as an appearance by no means uncommon ; and De 

 la Beche found, in the well-defined greensand near Lyme Regis, 

 on the coast of Dorsetshire, impressions of ferns. Gideon Man- 

 tell also, has already mentioned, as occurring in the chalk of 

 Sussex, at Hanisey, at Lewes, and at Brighton, the stems with^A 

 remains of leaves and distinct cones, which he compares with the 

 fruit of the Pinus Larix. (Geology of Sussex, p. 103, tab. ix.) 

 Count Sternberg has more recently referred these parts to an 

 undetermined species of the genus Conites, and in every instance 

 they seem to have been originally land plants. 



We find these appearances more abundant in the strata be- 

 longing to the chalk formation of Germany. The greensand 

 {quader-sandstein) and the pldnerkalk of Saxony and Bohemia, 

 the complete identity of which with the strata of greensand 

 and crai tu/eau, we may consider proven, afford numerous ex- 

 amples of them. That we may not be detained by unsatisfactory 

 references, we will adduce the observations made by Count 

 Sternberg. He describes and figures, as occurring in the pldn- 

 erkalk of the lordship of Schmetschna in Bohemia, a species of 

 the Gutting Thuites, (Th. alienus, Synopsis, p. xxxviii. Fasc. 

 iv. p. 40. tab. Ixv. f. 1.) of the family Conifer cb ; and also 

 leaves of trees of the class of Dicotyledones, which are here 

 represented as a thing by no means uncommon in the green- 

 sand {quader-sandstein) near Tetcschen, so well known to geo- 

 logists, (Tab. XXV. f. 1. a. b.) Exactly the same relation oc- 

 curs in the contemporary strata distributed in the immediate 

 neighbourhood of the Hartz. The leaves of Dicotyledones, so 

 abundantly found in the greensand at Heidelberg near Blank- 

 enburg, are generally known. They are found along with 

 trunks and branches, and cannot possibly, from the perfect pre- 

 servation of their parts, derive their origin from older formations. 

 In an exactly similar way we found leaves and fragments of large 

 trees in the clay-beds of the same greensand {quader-sandstein) 

 at Qucdlinburg. They are there immediately connected with 

 the strata of a chalky marl abundantly filled with green colour- 

 ed grains, and abounding in distinctly defined remains of testa-
