embossed centre, and an apex somewhat thickened, and ap- 

 proaching the obtuse triangular scar that the leaves of many 

 plants leave after falling off, with the decurrent swelling 

 below. The nearest approach to this regular lozenge for- 

 mation is in the small branches of some species of pines, 

 Euphorbiae or Proteas. From the larger flatted impressions 

 and the smaller branched ones, it should appear that this was 

 not a very small species of plant. I have a flattened im- 

 pression that is seven inches wide, and this specimen is 

 smaller than some others which I have, but was chosen for 

 its having the divided end, showing that the plant branched, 

 besides the sign of the two pith-like round holes, one for 

 each branch, remarkable for being on one side in these, as 

 well as in those not branching. The hollow is generally 

 longitudinally striated. 



The other specimen shows a smaller branch, with some 

 remains of leaves which are a little carinated, acute, in 

 length about twelve or sixteen times their breadth, and 

 swelling a little from their base. 



These specimens are both Ironstone, upon winch the 

 coaly remains of the plants are impressed. In the front 

 specimen, the Coal has the usual fracture, and is about the 

 tenth of an inch thick where the squamae are most distinct, 

 as one side has only little regular embossments, the squamaa 

 being obliterated by scaling off or wearing; or perhaps they 

 were never so perfectly formed, on account of their being in 

 a position less fitted to preserve them : this ought to be 

 noticed, lest in some instances it should lead to mistake in 

 the species. 



Other species of similar construction are found at Lord 

 Middleton's, Woollarton, near Nottingham. I have, among 

 other remarkable ones, some much branched, by favour of 

 Thomas Meade, Esq., from Poulton in Somersetshire.
