Excerpt from Heredity and Evolution in Plants Chapters X, Geographical Distribution, and XIII, The Great Groups of Plants, and the Bibliography are new. N o attempt has been made to cite the voluminous periodical literature in the Bibliography, but needless to state, this has been freely consulted and drawn upon. Numerous citations are given as foot-notes, especially in Chapter X. In going over the chapters it also became evident that since, in order to read them understandingly, one must have a clear conception of the facts of the lift history of a vascular plant, it would be best to introduce from the Fundamentals of Botany the three chapters (viz. XII XIV) on the life history of the fern. As stated in the Preface to that book, while the ultimate problem of botany is the development of the kingdom of plants, the more immediate and fundamental problem is the development of the individual plant. Ontogeny is fundamental because without a knowledge of its processes the processes of phylogeny cannot be comprehended. Phylogeny is the ultimate problem because its complete solution in volves an orderly description of all the phenomena of plant life, and their relation to each other. The author is specially indebted to Dr. 0. E. White, curator of plant breeding in the Brooklyn Botanic Garden, for a careful reading of the entire manuscript and for many valuable suggestions; also to Mr. Norman Taylor, curator of plants, in connection with Chapter X, and to Dr. Alfred Gundersen, associate curator of plants in the same institution, for numerous constructive criticisms in connection with Chapter XIII.

Excerpt from Heredity and Evolution in Plants The present little book was originally intended to be merely a reprint of Chapters XXXI to XXXVIII of the authors Fundamentals of Botany. The reprinting of those chapters was suggested by comments received from various correspondents, who pointed out that the subject matter which they cover had not been elsewhere presented in so concise a treatment in one volume, and in a manner suited, not only to beginning students, but also to more general readers. The chapter on Experimental Evolution has received the approval of the author of the mutation theory, as being an accurate presentation of the essentials of that theory. "I have especially appreciated," writes Professor de Vries, "the statement of the difference between fluctuating and saltative variation, which is, to my mind, the real empirical basis for the theory, far more than the experiments on mutation with single plants. The relation of my view to Darwinism is misunderstood by many authors, and it is a great satisfaction to me that you have outlined it in such a plain way." In the preparation of the copy for reprinting, considerable new matter has been added, certain sentences and paragraphs, pertinent only to an elementary text-book, have been omitted, and others recast, and several fresh illustrations have been introduced, either as new or as substitutes.

Excerpt from The Heredity of Acquired Characters in Plants With regard to definite variations, Sir E. R. Lankester is also at variance with Darwin. These are now regarded by him as what are called acquired characters which, he asserts, cannot be handed on by inheritance to a new generation. They are, he says, a direct re action to the environment. It does not affect the stirps, the inner reproductive germs.

Excerpt from Plant Genetics It should be realized that genetics is a natural out growth from the study of organic evolution. The con ception of evolution began as a speculation, but became scientific in connection with the work of lamarck and darwin. In such work the method used was that of Observation and inference. Facts were observed and an explanation was devised that would relate them. Resemblances and differences among species were noted, and it was inferred that these indicated degrees of relationship. It was assumed that closely related species must have had a comparatively recent common ancestry and that more distantly related species must have had a more remote common ancestry. Through comparisons of structure and of geographical distribution systems of phylogeny have been inferred, and an outline of the evolution of the plant and animal kingdoms has been the result. All of these conclusions are based upon comparison and inference. This method reached its extreme application in the work of darwin, whose observations included a range of forms and an extent of time unequaled by any pre ceding student oi evolution. It may be said that in darwin's work the method of comparison and infer ence reached the limit of its possibilities. The students of evolution were chiefly concerned With explaining the Changes that resulted in phylogeny. In other words.

Excerpt from Evolution and Genetics HE third reprinting Of the Vanuxem Lectures for 1915-16, entitled A Critique of the Theory of Evolution, having been exhausted, the publishers have asked for a revised edition. The revision is no less an attempt at a critique Of the evolution theory than its predecessor, but, as the change in title sug gests, greater attention is here paid to one Of the most debated questions among evolutionists today, namely, the bearing Of the recent discoveries in genetics and in mutation on the theory Of evolution. While in a general way Darwin's theory Of Natu ral Selection is independent Of the origin Of the new variations that furnish it with its materials, yet the scientific formulation Of the theory is intimately con nected with the origin and inheritance Of suitable vari ations. For instance, if most of the observed variabil ity Of animals and plants were due directly to the environment, and if the effects thus brought about were not inherited, such variability could no longer be appealed to as material for natural selection. Again, if the variations that appear as mutants are always defective types, they could not, even though they are inherited, be appealed to as furnishing ma terial for progressive evolution.

Excerpt from Heredity and Eugenics: A Course of Lectures Summarizing Recent Advances in Knowledge, in Variation, Heredity, and Evolution and Its Relation, to Plant, Animal, and Human Improvement Ment and Welfare During the summer of 1911, a course of lectures on heredity and allied topics was given at the University of Chicago, under the auspices of the biological departments. The purpose of the course was to present the recent develop ments of knowledge in reference to variation, heredity, and evolution, and the application of this new knowledge to plant, animal, and human development and improvement. The lectures were not intended for those trained in biology, but for a general university audience, interested in the progress of genetics as a matter of information rather than of study. The lecturers, therefore, did not address themselves to their colleagues, and did not attempt to include any considerable amount of new material. It is believed that a much larger audience than the one originally addressed might be interested in this summary of results in one of the important and recently cultivated fields of biology, and therefore this volume has been published. It is hoped that it may perform a service not only for those interested in biology as a field outside their own experience, but also for those biologists whose work deals with other phases of biology.
