Abstract
In the Quarterly Journal of the Geological Society for 1925 (Q.J.G.S., vol. lxxxi, p. 113) I discussed the conditions of deposition of the Stockdale Shales of Valentian age. I had intended to make a detailed study of the deposits of later Silurian age, but circumstances have prevented this. I propose to offer a few notes on the subject which may be of use to other observers.
