GENERAL LITERATURE-LIST

The following list includes only the titles of works actually referred to in the text and those immediately related to them. For more complete bibliography the reader Is referred to the literature-lists in the special works cited, especially the following. For reviews of the early history of the cell-theory see Remak's Untersuchungen ( ? 50-'55), Huxley on the Cell-theory ("53), Sach's History of Botany and Tyson's Cell-doctrine O78) . An exhaustive review of the earlier literature on protoplasm, nucleus, and cell-division will be found in Flemming's Zellsubstanz ('82), and a later review of theories of protoplasmic structure in BUtschli's Protoplasma ('92) and in Fischers Fixierung* etc., des Protoplasmas C99). The earlier work on mitosis and fertilization is very thoroughly reviewed in Whitman's Clepsine ('78), Fol's Hhiogenie ('79)« an d Mark's Umax ("81). For more recent general literature-lists see especially Hertwig's Zelle und Gewcbe ('93, '98), Yves Delage (95), Henneguy's Cellule ("96), Hacker's Praxis und Theorie der Zelle n und Befruchtungslehre ('99), and the admirable reviews by Flemming, Boveri, RUckert, Meves, Roux, and others in Merkel and Bonnet's Ergebnisse ('9 1-98).

The titles are arranged in alphabetical order, according to the system adopted in Minot's Human Embryology. Each author's name is followed by the date of publication (the first two digits being omitted, except in case of works published before the present century), and this by a single number to designate the paper, in case two or more works were published in the same year. For example, Boverl, Th., '87. 2, denotes the second paper published by Boveri in 1887.

Columbia University Biological Series.

EDITED BT

HENRY FAIRFIELD OSBORN,

Da Costa Professor of Zoology in Columbia Cnirtrsity.


This series is founded upon a course of popular University lectures given during the winter of 1892-3, in connection with the opening of the new department of Biology in Columbia College. The lectures are in a measure consecutive in character, illustrating phases in the discovery and application of the theory of Evolution. Thus the first course outlined the development of the Descent theory; the second, the application of this theory to the problem of the ancestry of the Vertebrates, largely based upon embryological data; the third, the application of the Descent theory to the interpretation of the structure and phylogeny of the Fishes or lowest Vertebrates, chiefly based upon comparative anatomy ; the fourth, upon the problems of individual development and Inheritance, chiefly based upon the structure and functions of the cell.

Since their original delivery the lectures have been carefully rewritten and illustrated so as to adapt them to the use of College and University students and of general readers. The volumes as at present arranged for include:

I. From the Greeks to Darwin. By Henry Fairfield

OSBORN.

II. Ampliioxus and the Ancestry of the Vertebrates.

I. FROM THE GREEKS TO DARWIN.

THE DEVELOPMENT OF THE EVOLUTION IDEA.

BY

HENRY FAIRFIELD OSBORN, Sc.D., Princeton,

Da Costa Prufe*nor of Zoology in Columbia University. 8vo. Cloth. $2.00, net.


This opening volume, " From the Greeks to Darwin," is an outline of the development from the earliest times of the idea of the origin of life by evolution. It brings together in a continuous treatment the progress of this idea from the Greek philosopher Thales (640 B.C.) to Darwin and Wallace. It is based partly upon critical studies of the original authorities, partly upon the studies of Zeller, Perrier, Quatrefages, Martin, and other writers less known to English readers.

This history differs from the outlines which have been previously published, in attempting to establish a complete continuity of thought in the growth of the various elements in the Evolution idea, and especially in the more critical and exact study of the pre-Darwinian writers, such as Buffon, Goethe, Erasmus Darwin, Treviranus, Lamarck, and St. Hilaire, about whose actual share in the establishment of the Evolution theory vague ideas are still current.

TABLE OF CONTENTS

I. The Anticipation and Interpretation of Nature. II. Among the Greeks.

III. The Theologians and Natural Philosophers.

IV. The Evolutionists of the Eighteenth Century. V. From Lamarck to 8t. Hilaire.

VI. The First Half-century and Darwin.

In the opening chapter the elements and environment of the Evolution idea are discussed, and in the second chapter the remarkable parallelism between the growth of this idea in Greece and in modern times is pointed out. In the succeeding chapters the various periods of European thought on the subject are covered, concluding with the first half of the present century, especially with the development of the Evolution idea in the mind of Darwin.

The purpose of this volume is to consider the problem of the ancestry of the Vertebrates from the standpoint of the anatomy and development of Amphioxus and other members of the group Protochordata. The work opens with an Introduction, in which is given a brief historical sketch of the speculations of the celebrated anatomists and embryologists, from Etienne Geoffroy St. Hilaire down to our own aay, upon this problem. The remainder of the first and the whole of tne second chapter is devoted to a detailed account of the anatomy of Amphioxus as compared with that of higher Vertebrates. The third chapter deals with the embryonic and larval development of Amphioxus, while the fourth deals more briefly with the anatomy, embryology, and relationships of the Ascidians; then the other allied forms, Balanoglossus, Cephalodiscus, are described.

The work concludes with a series of discussions touching the problem proposed in the Introduction, in which it is attempted to define certain general principles of Evolution by which the descent of the Vertebrates from Invertebrate ancestors may be supposed to have taken place.

The work contains an extensive bibliography, full notes, and 135 illustrations.
