Abstract
A HEARTY welcome must be extended to this new edition of one of our most widely known geological text-books, which has had considerable influence in seCuring systematic and accurate descriptions of rocks by British petrologists. The present edition contains a few pages less than the previous issue, but this has been accomplished by diminishing the space at the headings of chapters and by the excision of superfluous notes and references to occurrences of minor interest, so that the value of the book is in no way diminished. New illustrations have been added, and the chapters on metamorphism largely re-written.
