A text-book such as the present falls naturally into two sections which, for brevity, may be called Physical Geology and Stratigraphical Geology respectively. The first section, Chapters I to XV inclusive, has been written by Mr. Rastall; the second section, from Chapter XVI to the end, has been written by Mr. Lake. Each author is responsible for his own section only, but care has been taken to prevent omissions and to avoid any repetitions beyond what would be necessary in a work by a single author.In the preparation of the book the authors have received assistance from many friends to whom they desire to express their acknowledgements.In the Physical section Mr. C. Barrington Brown jun. helped in the final revision of the manuscript for the press and drew most of the diagrams which appear in this part of the book. In Mr. Rastall's absence abroad Mr. J. Romanes kindly corrected the proofs of this section of the book. Dr. Hatch also read the proofs and offered many valuable suggestions.In the Stratigraphical section the thanks of the authors are due especially to Mr. Henry Woods, who read the whole of this part in manuscript with the exception of the last chapter. The book has profited greatly from his advice. Mr. F. W. Harmer very kindly read the account of the Pliocene series and added many useful notes.Many of the illustrations are original.Tags: rocks beds water deposits lower rock north sea south upper form formed limestone occur forms material ice system geology surfaceCategory: Science - GeologyVisit Forgotten Books at: http://www.forgottenbooks.org
