176 Dr Hissert on the Limestone of Burdiehouse 
Hurron). The circumstances under which these vegetable relies 
are found, appear to be the same which had been previously re- 
marked in another and very distant locality. At Burdiehouse, 
the Lepidophyllum intermedium is found lying along with Cype- 
rites bicarinata. But whether this coincidence ought to stimulate 
to any fresh inquiry regarding the true character of each, I would 
not offer any opinion whatever, as it is but too possible that the 
association might have been purely accidental. At least, “ it is 
curious,” as Professor Linpuey has remarked to me, “ that these 
two fossils, which have no sort of relation to each other, should 
have occurred in association with each other, both in the Lee- 
botwood coal-pit and at Burdiehouse.” (Compare plate 43 of 
L. & Hs Fossil Flora with Fig. 5 of Plate VI, given in this 
memoir.) 
Regarding the cylindrical and imbricated cones supposed to 
be naturally connected with the Lepidodendron, (a notion to 
which much countenance is given by the character of the remains 
discovered at Burdiehouse), two kinds may be identified, viz. the 
Lepidostrobus variabilis, (Linpiey and Huron), Pl. 10 and 11), 
and the L. ornatus (ibid. Pl. 26). 
No cardiocarpon which can be safely attributed to Lycopo- 
diaceze has yet, to my knowledge, turned up. I have only ob- 
served the Cardiocarpon acutum of Messrs Linpiey and Hur- 
ron (See Foss. Flora, pl. 76), which is supposed by them to 
belong to other plants. 
These very general remarks must, on the present occasion, be 
deemed sufficient. 
It is thus shewn, that the smaller ferns, referable to Sphenop- 
teris, together with the disjointed organs of Lycopodiacez, con- 
stitute the great majority of vegetable remains entombed in the 
limestone of Burdiehouse. Along with these are found, but 
comparatively in less number or quantity, relics of the Stigma- 
na ficoides, and of the less common species belonging to Sigil- 
laria, Equisetum, Calamites, and Cyclopteris. But as attention is
