PREFACE

HIS small volume is the result of a need
that the author has felt, for some years,

for a concise text-book of embryology that described the development of both the chick and the frog. The only other single book, with which the author is acquainted, that describes the development of both these commonly studied forms is the large volume of Marshall, which is too cumbersome and expensive for a general, class text-book.

The present volume is intended as an outline, from which the student may learn the main facts about the embryology of the two animals in question; and the instructor is supposed in his lectures to enlarge upon this outline to any extent that he may see fit. Since the needs of the medical student have been largely considered in compiling the text, very little space has been given to theoretical discussions; these may be given by the instructor, at whatever length may seem desirable.

For purely pedagogical reasons, the development of the chick has been described by periods; that is, all the changes that take place during a certain period are described in one section, instead of describing at one time, the complete development of any one organ.

The author does not lay claim to any great originality in the compilation of this volume. He has sought simply to collect, into convenient form, the more important facts of the subject under discussion, together with a series of figures that will suitably illustrate these facts.

Marshall and Morgan have been quoted at length, in several instances.

Nearly all the figures have been taken from well-known text-books of embryology, the author being stated in every case.

I am especially indebted to Dr. Charles S. Minot and his publishers, P. Blakiston's Son & Co., for the loan of the electros of the numerous figures that have been taken from Professor Minot's recent Laboratory Text of Embryology ALBERT M. REESE.
