Abstract

THOSE interested in the early history of geology will be glad to learn that a work is announced as ready for publication, with the title, “A Book about William Smith and the Somersetshire Coal Canal; being an Account of the Commencement of Strati-graphical Geology in England.” The book is illustrated by a series of consecutive photographs of the districts along the north side of the Canal valley, and each photograph is accompanied by a geologically coloured key, which shows at a glance the outcrop of the various strata. This method is, as far as we know, quite original, and serves to show clearly the data with which Smith dealt in arriving at his discoveries.
