Abstract
THE first edition of this important memoir was published in 1900, and the need for a new edition has been made the occasion of certain additions and corrections, none of which can, however, be said to be of any serious importance. A good deal of pakeontological work has been done, especially perhaps in the Millstone Grit. Naturally, the active development of the collieries during the last quarter of a century has thrown valuable light upon the structure of the coalfield. The Carboniferous Lime- stone has been exhaustively studied and the question of its dolomitisation has been examined in detail. The fact that a quarter of a century of active work has necessitated so little change in any of the fundamental portions of the memoir is evidence of the care and thoroughness with which the work was originally done.
