Book Description
Excerpt from Contributions to Geology and Plant Physiology, 1917 Only a single foreign government had inaugurated Official geological work during the early portion Of this period. The Ordinance Survey Of Great Britain in 1830 made a small grant to H. F. De la Beche for the survey Of southwest Eng land, but it was not until later that he was definitely appointed to make a Geological Survey. Spain and Austria established Geological Surveys in 1847 and 1849, respectively, but it was not until the next decade that similar organizations were suc cessively established in Bavaria, Portugal, the Netherlands, Norway, Sweden, and Switzerland. Some years passed before the other foreign governments followed suit. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

Book Description
Excerpt from Contributions to Plant Physiology The work of this department has thus far been exclusively graduate work, so that all of our students are intellectually rather mature. The scarcity of opportunities for carrying on advanced work in plant physiology, together with the fact that numerous educational institutions offer opportunity for ele mentary academic courses in this and the related subjects, have made it appear undesirable to institute undergraduate courses here. Experience seems to show, furthermore, that the intellectual power of graduate students is greater among those who have migrated from one institution to another, than it is among those who have performed their undergraduate work in the same institution as that in which graduate work is undertaken. Whether a causal relation is mainly involved here is questionable, for the very fact of student migration generally bespeaks a serious purpose and a definite aim; but it is also undoubtedly true that student migration tends strongly to prevent and to obliterate provincial traits of men tal character, and to give to the student who has thus migrated one or more times a more extensive series of in terests and a deeper appreciation of relative values.

Book Description
Excerpt from Plant Physiology and Ecology The point of view and the methods of study first advanced in "Research Methods in Ecology" have proved so satisfactory in teaching as to make it desirable to embody them in a text-book. The present text has been based largely upon "Research Methods," though most of the matter is new or rewritten. The manner of treatment is essentially the same, but the subject-matter has been rearranged and broken up into a larger number of chapters. The plant is first considered as an individual, with respect to factor, function, and form, and then as a member of a plant group or formation. The reasons for regarding ecology and physiology as essentially the same have been given elsewhere, and need not be repeated here. An endeavor has been made to give the various parts of this vast field their proper importance. Since ecology and physiology are merged, it is manifestly impossible to give to either what would be regarded as a complete treatment by a specialist in either line. No attempt has been made to touch all the points in each, but it is thought that nothing really fundamental has been omitted. The book is intended for use with classes in second-year botany in college and university. In manuscript form, it has been in such use for two years with good results. Although the amount of laboratory and field work is large, it is possible to accomplish all of it in a course requiring 6-8 hours of laboratory time each week. This can be done only by careful planning on the art of both instructor and student, and for this reason the following suggestions are offered as aids. The instructor will find it imperative to plan in advance for the experiments for the whole year, in order that plants may be ready as needed. Seeds and fruits for the study of migration should be collected in the fall. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

Book Description
Excerpt from Principles of Plant Physiology During the past five years since the first edition of this book appeared, it has met with more favor in the eyes of teachers and students of the subject than the author (or the publishers) had anticipated even in the most sanguine moments. But during those five years much phytophysiological water has passed under the botanical bridge. Once again has come the task of deciding what matter shall be included and what shall not. There is also the question of maintaining the book within a reasonable size. N o self-respecting student can be expected to carry an elementary book of more than 500 pages. Most gospels are small; but revisions have a tendency to get bigger and (let us hope) better. An elementary text should be up to date and yet not con tain many disputable data. However, if one included in a text book only those facts to which every plant physiologist subscribed wholeheartedly all of the time, the author would finish with a mere pamphlet. A happy medium must be sought. Whether the teacher professor who reads this will think this golden mean has here been attained, will depend upon his personal predilections and the number of fields in which he is not a specialist. So in this, as in the previous edition, there has been an attempt to hold as much as possible to the essentials of a general, elementary course, bearing in mind that this elementary course may be pre paring the student for courses in horticulture, agronomy, or forestry; for more advanced courses in plant physiology; or for a more appreciative life in the nonprofessional world.

Book Description
Excerpt from Elementary Plant Physiology A translation of Oel's "Pflanzenphysiologische Versuche," by the author of this volume, was published in 1894, and the entire edition was exhausted within a few months after its appearance. A similar elementary text, "Experimental Plant Physiology," was prepared at once and published in 1895, the last copy of which was sold in October, 1901. Meanwhile the "Practical d104-book of Plant Physiology," presenting a brief outline of the entire subject, with details of experimental methods suitable for the exact analyses requisite in research work, has been brought, out. The present little volume has been arranged to replace the "Experimental Plant Physiology" (1895) and to meet the constantly increasing demand for a course in elementary demonstrations which may be followed by beginners in the subject of botany. Experimentation is purposely confined to the principles capable of demonstration by the simplest methods, and without the costly and complex apparatus of a fully equipped laboratory. Furthermore, an arrangement of the book into a number of courses has been made to meet the exigencies of instruction in schools of various types. I am indebted to Dr. C. C. Curtis, of Columbia University, and to Dr. H. M. Richards, of Barnard College, for many valuable suggestions and for their kindness in reading proofs.

Book Description
Excerpt from Practical d104-Book of Plant Physiology The extension of knowledge in all departments of botany during the last few years has widened the application of the principles of physiology; and altered the relative importance of many phases of the subject. The most notable development consists of the universal recognition of the underlying and basal importance of the irritability of the organism; "that there is no vital process which is uninfluenced by stimuli, which permit, cause, restrict, or regulate the particular action in question." A second conception of no less importance is that of the intricate correlation existing between all of the activities of the vegetal organism, and the reciprocal interaction of all physiological stimuli. The arrangement of the subject in the following pages is an effort to place before the student a method by which a working knowledge of the physiological complex of the plant may be acquired. The disposition of the subject matter entailed by this treatment consists, briefly stated, in the study of the particular functions and properties of the organism, in connection with the agencies and forces which influence or initiate them, and a consideration of the general processes of plant life. To this end the first portion of the book, inclusive of chapters I. - VII., is devoted chiefly to the special forms of irritability exhibited by typical organisms, and the second part is taken up with a more critical consideration of the broader phases of the activity of the plant: a treatment of the subject well adapted to the convenience of the independent worker, and to the exigencies of instruction.

Book Description
Excerpt from Experimental Plant Physiology Only the more important and better established portions of the subject are treated, and these in the manner already in gen eral use. With the rapid advance of investigation it is next to impossible that an elementary laboratory manual should include the latest results, especially when the essential points of many of them may yet be in controversy and need the critical treat ment which is certainly not within the province of a work of this character. In the hands of an instructor in touch with current botanical thought, such deficiencies are easily supplied. In the interests of precision, the term assimilation is here used exclusively to denote a general function of proto plasm, while the term photosynthesis, which was introduced into the translation of Oels' manual (preface and page is adopted to signify the special process of forming carbohydrates from carbon dioxide and water in the presence of chlorophyll and sunlight. The author is indebted to Mr. R. N. Day and Miss J. E. Tilden for the demonstration and drawing for Figure 32.
