Extract

The classification set forth in this paper is founded essentially on an examination of the junction-beds between the Silurian and the Devonian in the field. All the localities described have been studied personally by the writer, and in most cases the actual junction has been mapped on the 6-inch scale. The names of localities are taken from the 6-inch Ordnance Survey maps, the sheet number being quoted in each case.
