Excerpt from The Structure and Development of Mosses and Ferns: Archegoniatae Third Edition, Revised and Enlarged Since the first edition of the present work was published, the number of important investigations on the structure and development of the Archegoniatae has been so great that it has been found necessary to recast entirely certain portions of the work, this being especially the case with the chapters dealing with the eusporangiate Ferns. The whole book, however, has been carefully revised, and a good deal of new matter introduced, including two special chapters on the geological history of the Archegoniates, and the significance of the alternation of generations. Some of the new material incorporated in the present work is published for the first time; but much of it is based upon papers published by the writer since the first edition was published. The work of other investigators has been freely drawn upon, and acknowledgment has been made in all cases where statements or illustrations have been borrowed from other sources than the writer's own investigations. The large number of recent books and papers on the Archegoniates has involved an entire revision of the bibliography, which has been materially augmented. It is hoped that it will be found to be a fairly complete list of the more recent works bearing upon the structure of the Archegoniates. The results of more recent investigations have necessitated, in some cases, a modification of certain views expressed by the author in the earlier edition. In other cases, however, his views have been confirmed as the result of more complete knowledge of certain forms.
