Excerpt from book: these, which consist of teeth, jaws, and scales, more or less detached, are in such a position that they must have been embedded in cannel through the transporting agency of water. The Scotch cannel seams, in many instances, afford remains of fish under the same circumstances; and in the bastard cannels of Bradford, near Manchester, these ichthyic remains are very abundant. Among the cannels of Wigan, shells of the genus modiola occur, embedded in the mass; and this, too, confirms the opinion, that this substance had its origin in some way connected with the influence of water, and is antagonistic to the idea that the coal seams have arisen from the same causes which now produce peat-bogs. Ordinary coals rarely afford remains distinct from the mass of the coals, as already stated, and this may have resulted from the amount of decomposition which these latter may have undergone, having effaced all traces of organic forms, both as regards structure and appearances. In such of the Scotch cannels as contain a large amount of hydrogen, and which have been subject to only a small amount of change from compression and chemical alteration, as those of Boghead and Methill, we find stigmaria, both in the form of roots and rootlets, in a more perfect state of preservation than occurs in ordinary coal, or even in other varieties of cannel. These present such appearances as would result from the circumstances under which they have grown, and in which they now occur, and they induce us to conclude that the caii- nels which afford them were original?a mass of vegetable matter associated with mud, which furnished all the necessary condition for a luxuriant vegetation; and these cannels, along with the whole of the members of the coal group, tend to the inference that coal originated under the ...
