[P.161] fusible Clay, Rep. i. 179§ ; and also have shown, that 
the extinct Coaly vegetables, in this’respect, differ essen 
tially from our Bog Plants, or such as have formed 
Peat, which seem: to require a sandy soil for their 
growth, Rep. i. 308 and 312. 
Besides the mere thin hollow pipes, or thin flat 
leaves, which distinguish the plants of the regular Coal 
strata, the British Strata throughout their whole series, 
almost, present in places, numerous detached specimens 
of the solid or ligneous parts of vegetables, closely 
resembling /Vcod, which sometimes, though rarely, are 
found with the bark on them, (but never with Roots, any 
more than the Coal plants,) and more rarely with arms 
or main branches, but without any of the minuter 
branches or leaves: by far the greater number of spe- 
cimens of this fossil Wood, whether petrified, car- 
bonated, or rotten, are found in splinters or billets, 
as if, first forcibly rent from large trees, and afterwards, 
for a long time floated in water, where they have become 
worm-eaten, and much worn, in many instances. 
These circumstances attending fossil Woods, have 
greater difficulties attending them, than almost any of 
the Geological phenomena that Iam acquainted with ; 
—when and where did they grow?, how were they so 
| generally rent? and so universally, and through such 
Jong periods of time, diffused in the original Ocean? &c. 
I have been able to perceive no reasons, why the bottom 
of the primitive Waters may not have produced ligneous 
as well as less solid vegetables, where neither of such 
might require Roots (for such I believe are never found) 
to support them, owing to the quiet state of the waters, 
or to nourish them, any more than the curallines of 
our days,

scarcely taken any notice in his work, of the kind of 
crystallization, by which seanis or strata of Coal, are 
almost invariably found split (or capable of being so), 
into rhomboidal blocks, by nearly vertical joints ; the 
length-way joints being very generally called sdines, 
and the oblique and shorter end-joints, called cutters, 
(see Note on page 69): nor has he noticed, a curious 
§ In addition to eight or nine different Names, which I had found esta- 
blished, in different districts of Great Britain, for the infusible Clay, thus 
forming the floors of their several Coal-seams, I lately met with the term 
Warrant, in the Isle of Anglesea, as the general name for the substance and 
stratum, immediately below each of their Coals,
