"Pure gold throughout."-GUARDIAN. "Unquestionably the clearest and most complete elementary treatise on this subject that we possess in any language."-WESTMINSTER REview. QUESTIONS ON HUXLEY'S PHYSIOLOGY FOR SCHOOLS. By T. ALCOCK, M. D. 18mo. Is. 6d. 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 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. the preparation of this work free use has been made of the manuscript materials of the late Professor Henslow. CHEMISTRY. In PROFESSOR ROSCOE'S LESSONS IN ELEMENTARY 45. 6d. Elementary Class-Books-continued. 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. unhesitatingly pronounce it the best of all our elementary treatises on Chemistry."-MEDICAL TIMES. In ordering, please specify Macmillan's Edition. POLITICAL ECONOMY. 66 We POLITICAL ECONOMY FOR BEGINNERS. By MILLICENT This work has been written mainiy 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. In the New Edition each page has been carefully revised, and at the end of each chapter after the questions a few little puzzles have been added, which will add interest to the book and teach the learner to think for himself. "Clear, compact, and comprehensive."-DAILY NEWS. "The relations of capital and labour have never been more simply or more clearly expounded."– CONTEMPORARY REVIEW. 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. New 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 Elementary Class-Books—continued. 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. 66 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 Nebula. New Edition. 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." PRACTICAL CHEMISTRY. THE OWENS COLLEGE JUNIOR COURSE OF PRAC- This little book contains a short description of a course of Practical Chemistry, which an experience of many years has proved suitable for those commencing the study of the science. It is intended to supplement, not to supplant, instruction given by the teacher. The subject-matter has been very carefully compiled, and many useful cuts are introduced. ANATOMY. LESSONS IN ELEMENTARY ANATOMY. By ST. George This volume is intended to form one of the series of Elementary ClassBooks of Science, and the Lessons are intended in the first place for teachers, and for earnest students of both sexes, not already acquainted with human anatomy. The author has endeavoured, secondly, by certain additions and by the mode of treatment, to fit them for students in medicine, and generally for those acquainted with human anatomy, but desirous of learning its more significant relations to the structure of other animals; he therefore hopes his volume may serve as a hand-book of Human Morphology. The book is amply illustrated with carefully drawn woodcuts. MANUALS FOR STUDENTS. Flower (W. H.)-AN INTRODUCTION TO THE OSTEOLOGY OF THE MAMMALIA. Being the substance of the Course of Lectures delivered at the Royal College of Surgeons of England in 1870. By W. H. FLOWER, F.R.S., F.R.C.S., Hunterian Professor of Comparative Anatomy and Physiology. With numerous Illustrations. Globe 8vo. 7s. 6d. Although the present work contains the substance of a Course of Lectures, the form has been changed, so as the better to adapt it as a handbook for students. Theoretical views have been almost entirely excluded: and while it is impossible in a scientific treatise to avoid the employment of technical terms, it has been the author's endeavour to use no more than absolutely necessary, and to exercise due care in selecting only those that seem most appropriate, or which have received the sanction of general adoption. With a very few exceptions the illustrations have been drawn expressly for this work from specimens in the Museum of the Royal College of Surgeons. Hooker (Dr.)—THE STUDENT'S FLORA OF THE BRITISH ISLANDS. By J. D. HOOKER, C.B., F.R.S., M.D., D.C.L., Director of the Royal Gardens, Kew. Globe 8vo. IOS. 6d. The object of this work is to supply students and field-botanists with a fuller account of the Plants of the British Islands than the manuals hitherto in use aim at giving. The Ordinal, Generic, and Specific characters have been re-written, and are to a great extent original, and drawn from living or dried specimens, or both.
