In Mr. Buddle's excellent sections, published in the 'Transactions of the Natural History Society of Newcastle,' the extent of the several alternations of coal, sandstone, shale, &c., in the upper parts of this series are clearly shown. There is not much ironstone in the coal tracts of the Tyne and Wear. In Yorkshire, the total thickness of the coal formation is from 1000 to 1500 yards. In Lancashire arid Wales greater thickness must be ascribed to it. In South
