Its roots represent the stigmaria underclay; its bark the compact coal; its woody axis the mineral charcoal ; its fallen leaves and fruits, with remains of herbaceous plants growing in its shade, mixed with a little earthy matter, the layers of coarse coal. The condition of the durable outer bark of erect trees, concurs with the chemical theory of coal, in showing the especial suitableness of this kind of tissue for...

It is also probable that the comparative impermeability of the...
