From this seam I was so fortunate as to procure a few fragments of fossil plants that seemed to be unmistakably of the true Coal-measures; and thus the important difference between them and the lignites of the Levant was at once evident to me. In the roof of this mine I observed an impression of what appeared to be an almost circular leaf, that measured nearly 4 feet in diameter.

Mr. Barkley informed me that in one of the mines trunks of trees had also been found in situ, the diameter of which never exceeded about one foot,—the outer part of these trunks being converted into pure coal, whilst the interior or core was composed of
