Excerpt from The Elementary Principles of General Biology In this book I have endeavored to present in an elementary way some of the fundamental generalizations that are the product of modern research in biology. The artificial division between the study of plants and that of animals is one that is becoming increasingly difficult to maintain, inasmuch as some biological principles are best illustrated by phenomena in the plant world, others by those of the animal world. T have tried, therefore, to utilize both aspects of the subject and to draw my illustrative material impartially from both kingdoms. The practice that insists upon the student getting his knowledge of natural science at first hand needs nowadays no justification. The laboratory method of study has shown itself to be not only the best means of acquiring a concrete and accurate knowledge of the science studied but also a primary prerequisite for those habits of thought that are essential to what has come to be known as the "scientific method." Nevertheless in Biology the field is so broad and so varied that the student is very likely to lose sight of the fundamental principles that underlie all living nature.

Excerpt from General Biology, Vol. 1 Several years ago it was our good fortune to follow as grad uate students a course of lectures and practical study in General Biology, under the direction of Professor Martin, at Johns Hop kins University. Since that time we have ever been strongly of the opinion that beginners in Biology should be introduced to the subject by some similar method, following in the main the outlines marked out by Huxley and Martin more than ten years ago. The present work thus owes its origin to the influence of the authors of the Elementary Biology, our deep indebtedness to whom we gratefully acknowledge.

Excerpt from Elementary Biology: Plant, Animal, Human IN the Preface to Plant Biology we discussed the general point of view that we believed should be emphasized in a course in elementary biology for students of high school age. We there stated that in our judgment the primary emphasis in the whole course should be placed on the many relations of biology to human welfare. Many. Of the experiments in that volume, especially those relating to the chemical com position of lifeless and living things, the tests for the food substances, and the principles of osmosis and of respiration, apply equally well in the discussion of animal and human biology.

Excerpt from The Principles of Biology, Vol. 1 of 2 1. OF the four chief elements which, in various com binations, make up living bodies, three are gaseous' under all ordinary conditions and the fourth is a solid. Oxygen, hydrogen, and nitrogen are gases which for many years defied all attempts to liquefy them, and carbon is a solid except perhaps at the extremely high temperature of the electric arc. Only by intense pressures joined with extreme refrigerations have the three gases been reduced to the liquid form.* There is much significance in this. When we remember how those redistributions of Matter and Motion which constitute Evo lutien, structural and functional, imply motions in the units that are redistributed; we shall see a probable meaning in the fact that organic bodies, which exhibit the phenomena of Evolution in so high a degree, are mainly composed of ultimate units having extreme mobility. The properties of substances, though destroyed to sense by combination, are not destroyed in reality. It follows from the persistence of force, that the properties of a compound are resultants of the properties of its components - resultants in which the pro perties of the components are severally in full action, though mutually obscured. One of the leading properties of each. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

Excerpt from An Introduction to the Study of General Biology: Designed for the Use of Schools and Science ClassesIn the preparation of this work, designed, as it is, to meet the wants of junior science students in connection with the Science and Art Department, the Syllabus of the Elementary Stage in General Biology has been followed. It is not intended, however, to supersede the use of the scalpel or microscope, or.oral instruction from a competent teacher. On the contrary, it is hoped that, with its aid, and with the other helps recommended, the student will examine the great field of nature for himself, and thus acquire that kind of knowledge which it is most desirable and delightful to possess - namely, the knowledge derived from a patient questioning and examination of those Obj ects in nature to which one's studies are Specially.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.

Excerpt from The Principles of Biology, Vol. 1 For aid in executing it, I owe many thanks to Prof Hux ley and Dr. Hooker. They have supplied me with information where my own was deficient; and in looking through the proof-sheets, have pointed out errors of detail into which I had fallen. By having kindly rendered me this valuable assist. Ance, they must not, however, be held committed to any of the enunciated doctrines that are not among the recognized ti uths of Biology.

Excerpt from An Introduction to General Biology The third change is the omission of the laboratory directions, these having been found unsuitable. The needs of different teachers differ so widely that it is impossible to draw up a scheme that shall answer for all. In place of the laboratory directions for students we have therefore given, in an appendix, a series of prae tical suggestions to teachers, leaving it to them to work out de tailed directions, if desired, by the help of the standard labora tory manuals. These suggestions are the result of a good deal of experience on the part of many teachers besides ourselves, and we hope they will be found useful in procuring and preparing material (often a matter of considerable difficulty), and in decid ing just what the student may reasonably be expected to do. For the rest, the original matter has been thoroughly revised. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

Excerpt from General Principles Zoology But meanwhile the subject of Zoology has widened 1, for, apart from its relations to man, Zoology has to explain the organization of animals and their relations to one another. This is a rich field for scientific activity; its enormous range is a consequence, on the one hand, of the well-nigh exhaustless variety of animal organization, and, on the other hand, of the different points of view from which the zoologist enters upon the solution of his problem.

Excerpt from Practical Plant Biology: A Course of Elementary Lectures on the General Morphology and Physiology of Plants At the outset the use of the microscope is treated, and special consideration is given to microscopic measurement and to the reconstruction of microscopic objects in the solid. The plants chosen as subjects of study are necessarily limited in number. They have been selected, as fairly representing some of the more important subdivisions of the vegetable kingdom, and as being, at the same time, easy to procure. Attention is directed only to those points of their structure, life, history, and manner of living which are necessary in order that the student should appreciate some of the general principles of morphology, physiology, and evolution. The lectures deal first with the simpler forms, among which are to be found some of the most important so far as general biology is concerned. They then pass on to the more complicated, and gradually lead the student to some knowledge of the development, structure, and physiology of the higher plants.

Excerpt from The Teaching of General Science Never before in this country has there been so insistent a demand for a more thorough and more comprehensive system of instruction in practical science. Forced by recent events to compare our education with that of other nations, we have suddenly become aware of our negligence in this matter. Now industrial and educational experts and commissions are united in demanding a change. While on the whole there has been a steady increase in the amount of time given to science work in the secondary and elementary schools, the attention paid to it, especially in the elementary schools, has been some what spasmodic, and its administration has been more or less chaotic. This is not due to lack of interest on the part of school officials but to their dissatisfaction with the methods of instruction employed. There is no doubt that superintendents would gladly introduce more science if they felt sure that the educational results would be commensurate with the time expended. This is indicated by a recent survey of about one hundred and fifty cities in seven states of the Central West. The survey shows that two-thirds of them have nature study in the elementary schools and that all are re quiring some science for graduation from the high school. The average high school is offering three years of science. Since 1900 there has been a greater increase in the percentage of students enrolled in science in the high schools than in any other subject with the one exception of English. Moreover, greater attention is now being paid to the training of teachers in methods of presentation of science. X The chief needs in science instruction today are a more efficient organization of the course of study with a View to its socialization and practical application, and a clear-cut realization on the part of the teacher of the aims, the principles of organization, and the methods of instruction; it is to meet these needs that this series is being issued. The books attempt to present such generalizations of science as the average pupil should carry away from his school experience and to organize them for the preparation of the teacher and for presenta tion to the class. The volumes will therefore be of three kinds: (1) source books with accompanying field and laboratory guides for the use of students in normal schools and schools of education, and of teachers, (2) pupils' texts and notebooks, and (3) books on the teaching of the various science subjects. In the first the material will be organized with special reference to the training of the teacher and the most effective methods of presenting the subject to students. In the second the matter will be simplified, graded, and arranged in such a way that the books will serve as guides in science work for the pupils themselves. Moreover, they will furnish texts for the grades and high school that will simplify the teacher's task of presentation and will assure well-tried and well-organized experiences, on the part of the pupil, with natural objects. This series of texts for elementary and secondary schools will have dependent continuity and the subject-matter will gradually increase in difficulty to accord with the increasing capacity of the pupils. It will furnish a unified course in science. The third type of book is for the teacher and deals with the history, aims, principles of organization, and methods of instruction in the several sciences.
