They found that 23 bore no resemblance to any plant known in 
this country ; and the remaining 88 are such as appeared to be like — 
were not unlike — or were very little different from, certain known 
plants. The doubtful manner in which these are spoken of, and 
the little agreement which it is now known exists between these 
impressions, and known recent plants, give us ground of supposition 
that these were the remains of plants which are unknown to this 
country*. 
The plant figured at PI. IV. Fig. 5, is evidently depicted also by 
Scheuchzer in PI. I. Fig. 7> p- 16, Herbarii Diluviani. He says, 
“ Est filicula, et quidem filicula fontana major, sive adianthum al- 
bum filicis folio. C. B. Pin. 358. Adianthum album filicis folio. 
J. B. III. 733 ,” &c. The specimen agrees with that which is here 
depicted, in other respects also. The stone, which came from 
Silesia, is of a margaceous kind, and of an ash colour, tinged with 
iron ; the plant itself being dark. The specimen of Scheuchzer was 
also obtained from a coal-mine, at Altwasser, in Silesia. 
The appearance of the specimen PI. III. Fig. 3, and which is 
represented with the strictest fidelity, is exceedingly uncommon. 
The matrix is a fine grained sand-stone ; and the vegetable form 
which it bears is produced merely by a very superficial stain of 
bitumen. Fig. 6, of the same Plate, displays a fossil frequently 
found in the iron-stone of Coalbrook-dale, of Derbyshire, &c. In 
the centre may be discerned a stalk, with a reticulated, or rather
