The peat bog is a great mass of vegetable matter, which is every year growing thicker and thicker; and underneath it there is almost always a bed of thin clay, in look very much like the underclays, and this thin clay is penetrated by the rootlets of the moss forming the peat, exactly the same way as the underclays of the coal measures are penetrated by the stigmaria and its rootlets.

Amongst the most remarkable are -- the sigillaria, of which large stems are very abundant, shewing that the interior has been soft, and the exterior fluted with separate leaves inserted in vertical rows along the flutings -- and the stigmaria, plants apparently calculated to flourish in marshes or pools, having

The present rich specimen does seem, however, to bear the specific stamp; and, from the peculiar character of the termination of another specimen on the table, I am inclined to hold that the stigmaria may have borne the appearance rather of underground stems than of proper roots.

In some pieces the tremolite assumes the common fan-like form; in some, the crystals, lying at nearly right angles with each other, present the appearance of ancient characters inlaid in the rock; in some they resemble the footprints of birds in a thin layer of snow; and in one curious specimen picked up by Mr. Swanson, in which a dark linear strip is covered transversely by crystals that project thickly from both its sides, the appearance presented is that of a minute stigmaria of the Coal Measures, with the leaves, still bearing their original green color, bristling thick around it.
