SCIENCE. ELEMENTARY CLASS-BOOKS. THE importance of Science as an element of sound education is now generally acknowledged; and accordingly it is obtaining a prominent place in the ordinary course of school instruction. It is the intention of the Publishers to produce a complete series of Scientific Manuals, affording full and accurate elementary information, conveyed in clear and lucid English. The authors are well known as among the foremost men of their several departments; and their names form a ready guarantee for the high character of the books. Subjoined is a list of those Manuals that have already appeared, with a short account of each. Others are in active preparation; and the whole will constitute a standard series specially adapted to the requirements of beginners, whether for private study or for school instruction. ASTRONOMY, by the Astronomer Royal. POPULAR ASTRONOMY. With Illustrations. By G. B. AIRY, Astronomer Royal. Sixth and cheaper Edition. 18mo. cloth. 4s. 6d. This work consists of six lectures, which are intended to explain to intelligent persons the principles on which the instruments of an Observatory are constructed (omitting all details, so far as they are merely sub Elementary Class-Books-continued. sidiary), and the principles on which the observations made with these instruments are treated for deduction of the distances and weights of the bodies of the Solar System, and of a few stars, omitting all minutie of formula, and all troublesome details of calculation." The speciality of this volume is the direct reference of every step to the Observatory, and the full description of the methods and instruments of observation. ASTRONOMY. MR. LOCKYER'S ELEMENTARY LESSONS IN ASTRO- The author has here aimed to give a connected view of the whole subject, and to supply facts, and ideas founded on the facts, to serve as a basis for subsequent study and discussion. The chapters treat of the Stars and Nebule; the Sun; the Solar System; Apparent Movements of the Heavenly Bodies; the Measurement of Time; Light; the Telescope and Spectroscope; Apparent Places of the Heavenly Bodies; the Real Distances and Dimensions; Universal Gravitation. The most recent astronomical discoveries are incorporated. Mr. Lockyer's work supplements that of the Astronomer Royal mentioned in the previous article. "The book is full, clear, sound, and worthy of attention, not only as a popular exposition, but as a scientific 'Index.'"-- ATHENÆUM. "The most fascinating of elementary books on the Sciences."-NONCONFORMIST. QUESTIONS ON LOCKYER'S ELEMENTARY LESSONS IN ASTRONOMY. For the use of Schools. By JOHN FORBES. ROBERTSON. 18mo. cloth limp. Is. 6d. PHYSIOLOGY. PROFESSOR HUXLEY'S LESSONS IN ELEMENTARY Elementary Class-Books-continued. This book describes and explains, in a series of graduated lessons, the principles of Human Physiology; or the Structure and Functions of the Human Body. The first lesson supplies a general view of the subject. This is followed by sections on the Vascular or Venous System, and the Circulation; the Blood and the Lymph; Respiration; Sources of Loss and of Gain to the Blood; the Function of Alimentation; Motion and Locomotion; Sensations and Sensory Organs; the Organ of Sight; the Coalescence of Sensations with one another and with other States of Consciousness; the Nervous System and Innervation; Histology, or the Minute Structure of the Tissues. A Table of Anatomical and Physiological Constants is appended. The lessons are fully illustrated by numerous engravings. "Pure gold throughout."-GUARDIAN. questionably the clearest and most complete elementary treatise on this subject that we possess in any language."-WESTMINSTER REVIEW. "Un QUESTIONS ON HUXLEY'S PHYSIOLOGY FOR SCHOOLS. These Questions were drawn up as aids to the instruction of a class of young people in Physiology. BOTANY. PROFESSOR OLIVER'S LESSONS IN ELEMENTARY Twelfth This book is designed to teach the Elements of Botany on Professor Henslow's plan of selected Types and by the use of Schedules. The earlier chapters, embracing the elements of Structural and Physiological Botany, introduce us to the methodical study of the Ordinal Types. The concluding chapters are entitled, "How to dry Plants" and "How to describe Plants." A valuable Glossary is appended to the volume. In the preparation of this work free use has been made of the manuscript materials of the late Professor Henslow. D Elementary Class-Books-continued. CHEMISTRY. PROFESSOR ROSCOE'S LESSONS IN ELEMENTARY 4s. 6d. It has been the endeavour of the author to arrange the most important facts and principles of Modern Chemistry in a plain but concise and scientific form, suited to the present requirements of elementary instruction. For the purpose of facilitating the attainment of exactitude in the knowledge of the subject, a series of exercises and questions upon the lessons have been added. The metric system of weights and measures, and the centigrade thermometric scale, are used throughout the work. The new Edition, besides new wood-cuts, contains many additions and improvements, and includes the most important of the latest discoveries. "As a standard general text-book it deserves to take a leading place."-SPECTATOR. " We unhesitatingly pronounce it the best of all our elementary treatises on Chemistry."-MEDICAL TIMES. POLITICAL ECONOMY. POLITICAL ECONOMY FOR BEGINNERS. By MILLICENT This work has been written mainly with the hope that a short and elementary book might help to make Political Economy a more popular study in boys' and girls' schools. In order to adapt the book especially for school use, questions have been added at the end of each chapter. "Clear, compact, and comprehensive."-DAILY NEWS. "The relations of capital and labour have never been more simply or more clearly expounded.— CONTEMPORARY REVIEW. Elementary Class-Books-continued. LOGIC. ELEMENTARY LESSONS IN LOGIC; Deductive and Inductive, with copious Questions and Examples, and a Vocabulary of Logical Terms. By W. STANLEY JEVONS, M. A., Professor of Logic in Owens College, Manchester. Second Edition. 18mo. 3s. 6d. In preparing these Lessons the author has attempted to show that Logic, even in its traditional form, can be made a highly useful subject of study, and a powerful means of mental exercise. With this view he has avoided the use of superfluous technical terms, and has abstained from entering into questions of a purely speculative or metaphysical character. For the puerile illustrations too often found in works on Logic, examples drawn from the distinct objects and ideas treated in the natural and experimental sciences have been generally substituted. At the end of almost every Lesson will be found references to the works in which the student will most profitably continue his reading of the subject treated, so that this little volume may serve as a guide to a more extended course of study. The GUARDIAN thinks "nothing can be better for a school-book," and the ATHENÆUM calls it " a manual alike simple, interesting, and scientific." PHYSICS. LESSONS IN ELEMENTARY PHYSICS. By BALFOUR STEWART, F.R.S., Professor of Natural Philosophy in Owens College, Manchester. With numerous Illustrations and Chromoliths of the Spectra of the Sun, Stars, and Nebulæ. Fifth Thousand. 18mo. 4s. 6d. A description, in an elementary manner, of the most important of those laws which regulate the phenomena of nature. The active agents, heat, light, electricity, etc., are regarded as varieties of energy, and the work is so arranged that their relation to one another, looked at in this light, and the paramount importance of the laws of energy, are clearly brought out. The volume contains all the necessary illustrations, and a plate representing the Spectra of Sun, Stars, and Nebulæ, forms a frontispiece. The EDUCATIONAL TIMES calls this "the beau ideal of a scientific text-book, clear, accurate, and thorough," |
