They arc, in short, loamy or clay soils, and must have been sufficiently above wate to admit of drainage. The absence of sulphurets, and the occurrence of carbonate of iron in connexion with them, prove that, when they existed as soils, rain-water, and not sea-water, percolated them. (5.) The coal and the fossil forests present many evidences of subaerial conditions. Most of the erect and prostrate trees had b' ome hollow shells of bark before they were finally imbedded, and : .eir Avood had broken into cubical pieces of mineral charcoal. Land-snails and galley-worms [Xijlohius) crept into them, and they became dens or traps for reptiles. Large ((uantities of .'ninoral charcoal occur on the surfaces f)f all the larger beds of coal. None of these appearances could have been produced by suba([neous action. (6.) Though the roots of Siff/'llaria bear some resemblance to the rhizomes of certain aquatic plants, yet structurally they are absolutely identical with the roots of Cycads, which the stems also resemble. Further, the SigiUarim grew on the same soils which supported ('onifers, Lrpidodcndra, Cardaitcs, and ferns—plants which could not have grown in water. Again, with the exception, perhaps, of sonic Pinnularke and Asiei-op/ii/llitcs, there is a remarkable absence from the coal measures of any form of properly aquatic vegetation. (7.)
