OUTLINES OF CHORD ATE DEVELOPMENT BY WILLIAM E. KELLICOTT FROFE8SOB OP BIOLOGY IN GOUCHER COLLEGE NEW YORK HOLT AND COMPANY. COPYRIGHT, 1913, BY HENRY HOLT AND COMPANY September, 1934 N. R. A. PREFACE In these Outlines the student is introduced to the study of Chordate development through the embryological history of Amphioxus. Whether or not Amphioxus represents a truly primitive type of development, it affords, in simple diagram matic style, the essentials of early Chordate ontogeny. In many respects the later phases of its history are highly modi fied, but this need be no objection to its use as an introductory type, since it may serve immediately to put the student upon his guard against a too exact phylogenetic interpretation of embryological facts. Following this is a rather full account of the development of the frog, a form that represents, better than any other single type, what we may regard as the general type of Chordate development. The chapters on the chick are relatively briefer and emphasis is laid upon the embryonic membranes, and upon the early phases of development, which represent the most frequent modifications of the type of Chordate development, modifications correlated with the presence of the large yolk accumulation of the Sauropsid ovum. It is believed that the chapters on the frog and chick have been written in such a way that either form may be omitted, in a brief course of study. Of in case the study of the early development of the frog is desired as a comparative introduc tion to the study of the embryology of the chick, Chapter III, on the organogeny of the frog, may be omitted without serious interruption of the continuity of such a course. The finalchapter on the Mammal includes only those phases of development that are of chief interest to the general student namely, the earlier stages in the formation of the embryo, the establishment of its relation with the maternal organism, the developmeBt of the embryonic membranes and appendages, the development of tile external form of the human embryo, iii iv PREFACE Several authors and publishers have very kindly permitted the use of illustrations or cliches from their works. Especial acknowledgement is made to Professor F. R. Lillie for permis sion to use a considerable number of the illustrations in his Development of the Chick Henry Holt and Co., I am also indebted to Professor C. S. Minot and P. Blakistons Son and Co., for several cliches from their Laboratory Text-book of Embryology 7 to Professor J. Playfair McMurrich and P. Blakistons Son and Co., for cliches from their Development of the Human Body to Messrs. Longmans Green and Co., for cliches from Quains Anatomy to Messrs. G. P. Putnam and Co., for permission to redraw, with some modifications in most instances, certain illustrations in Marshalls Vertebrate Embryology to Professor T. H. Morgan and The Macmillan Company, for cliches from their Development of the Frogs Egg and to Herr Gustav Fischer and the respective authors, for cliches from 0. Hertwigs Handbuch der vergleichenden und experimentellen Entwickelungslehre der Wirbeltiere 0. Hertwigs Lehrbuch der Entwickelungsgeschichte des Men schen und der Wirbeltiere and H. E.
