Extract

In last month's Geological Magazine there is much (by three writers) that bears upon the Devonian Question, and I would now add a few words on the same subject, which is of the greatest interest to me.

page 125 note 1 Of all areas in which rocks belonging to the Siluro-Carboniferous interval are developed, that of the Welsh border counties, although geographically the nearest, is perhaps the least comparable of any to the North Devon area, and the greatest stumbling-block to a would-be "Devonian" disciple. In vain maybe the search there for a break of any magnitude to be filled in from the latter area. Lacustrine conditions may have prevailed more or less, from the final retreat of the Ludlow types, until the waters of the Lower Limestone Shale united the " Welsh Lake " (see Prof. Geikie's Lectures oh the Old Red Sandstone) with the ocean. In South Ireland sod Devonshire, on the other hand, there are plain indications of an open sea to the South and East, extending into the Rhine country.
