1. Carboniferous Limestone near Clitheroe, and along the axis of the supposed ridge under the Cheshire Plain.
2. Yoredale series, cropping out along the flanks of the Pendle Range, and, along with the Millstone Grit, becoming attenuated southwards, and terminating against the shelving flanks of the Silurian rocks in Shropshire (on the right-hand side of the woodcut).
3. Millstone-Grit series.
4. Coal-measures of the South-Lancashire Coal-field, dipping under the Permian and Triassic rocks of Cheshire, then flattening and rising towards the south, and dissevered from the Coal-measures of Shropshire by the supposed axis of elevation.
5 a. Permian series of the Lancashire type, resting discordantly on the Carboniferous rocks, consisting of red marls with limestone in the upper series, and of soft red sandstone in the lower.
5 b. Permian series of the Salopian type, separated from the Lanca shire beds by the ridges of Carboniferous rocks, and consisting of purple sandstones and marls, breccia and conglomerates, &c.
6. Bunter Sandstone, becoming thinner towards the south and on approaching the Palœzoic axis.
7. Keuper Marls and Sandstone of the Central Plain of Cheshire.
