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. LESSONS IN ELEMENTARY PHYSICS. By BALFOUR 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 Nebula, forms a frontispiece. The EDUCATIONAL TIMES calls this "the beau ideal of a scientific text-book, clear, accurate, and thorough." 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 These Lessons are intended for teachers and students of both sexes not already acquainted with Anatomy. The author has endeavoured, by certain additions and by the mode of treatment, also 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. The LANCET says, "It may be questioned whether any other work on Anatomy contains in like compass so proportionately great a mass of information." The MEDICAL TIMES remarks, "The work is excellent, and should be in the hands of every student of human anatomy." 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. "Cannot fail to perfectly fulfil the purpose for which it is intended."-LAND AND WATER. Containing the fullest and most accurate manual of the kind that has yet appeared."-PALL MALL GAZETTE. 66 D Oliver (Professor).—FIRST BOOK OF INDIAN BOTANY. By DANIEL OLIVER, F.R.S., F.L.S., Keeper of the Herbarium and Library of the Royal Gardens, Kew, and Professor of Botany in University College, London. With numerous Illustrations. Extra fcap. 8vo. 6s. 6d. This manual is, in substance, the author's "Lessons in Elementary Botany," adapted for use in India. In preparing it he has had in view the want, often felt, of some handy résumé of Indian Botany, which might be serviceable not only to residents of India, but also to any one about to proceed thither, desirous of getting some preliminary idea of the Botany of that country. "It contains a well-digested summary of all essential knowledge pertaining to Indian botany, wrought out in accordance with the best principles of scientific arrangement."—ALLEN'S INDIAN MAIL. Other volumes of these Manuals will follow. Ball (R. S., A.M.)-EXPERIMENTAL MECHANICS. A Course of Lectures delivered at the Royal College of Science for Ireland. By ROBERT STAWELL BALL, A. M., Professor of Applied Mathematics and Mechanics in the Royal College of Science for Ireland (Science and Art Department). Royal 8vo. 16s. The author's aim has been to create in the mind of the student physical ideas corresponding to theoretical laws, and thus to produce a work which may be regarded either as a supplement or an introduction to manuals of theoretic mechanics. To realize this design, the copious use of experimental illustrations was necessary. The apparatus used in the Lectures, and figured in the volume, has been principally built up from Professor Willis's most admirable system. In the selection of the subjects, the question of practical utility has in many cases been regarded as the one of paramount importance. The elementary truths of Mechanics are too well known to admit of novelty, but it is believed that the mode of treatment which is adopted is more or less original. This is especially the case in the Lectures relating to friction, to the mechanical powers, to the strength of timber and structures, to the laws of motion, and to the pendulum. The illustrations, drawn from the apparatus, are nearly all original, and are beautifully executed. Clodd. THE CHILDHOOD OF THE WORLD: a Simple By EDWARD CLODD, F.R.A.S. Account of Man in Early Times. Second Edition. Globe 8vo. 35. "I read PROFESSOR MAX MULLER, in a letter to the Author, says: your book with great pleasure. I have no doubt it will do good, and I hope you will continue your work. Nothing spoils our temper so much as having to unlearn in youth, manhood, and even old age, so many things which we were taught as children. A book like yours will prepare a far better soil in the child's mind, and I was delighted to have it to read to my children." Cooke (Josiah P., Jun.)-FIRST PRINCIPLES OF CHEMICAL PHILOSOPHY. By JOSIAH P. COOKE, Jun., Ervine Professor of Chemistry and Mineralogy in Harvard College. Crown 8vo. I25. The object of the author in this book is to present the philosophy of Chemistry in such a form that it can be made with profit the subject of College recitations, and furnish the teacher with the means of testing the student's faithfulness and ability. With this view the subject has been developed in a logical order, and the principles of the science are taught independently of the experimental evidence on which they rest. Guillemin.-THE FORCES OF NATURE: a Popular Intro duction to the study of Physical Phenomena. By AMEDEE GUILLEMIN. Translated from the French by Mrs. NORMAN LOCKYER, and Edited, with Additions and Notes, by J. NORMAN LOCKYER, F.R.S. With II Coloured Plates and 455 Woodcuts. Second Edition. Royal 8vo. cloth, gilt. 31s. 6d. "Translator and Editor have done justice to their trust. The text has all the force and flow of original writing, combining faithfulness to the author's meaning with purity and independence in regard to idiom; while the historical precision and accuracy pervading the work throughout, speak of the watchful editorial supervision which has been given to every scientific detail. . . . Altogether, the work may be said to have no parallel, either in point of fulness or attraction, as a popular manual of physical science."SATURDAY REVIEW. Lockyer.-THE SPECTROSCOPE AND ITS APPLICA TIONS. By J. NORMAN LOCKYER, F.R.S. With Coloured Plate and numerous illustrations. Second Edition. Crown 8vo. 3s. 6d. This forms volume one of "Nature Series," a Series of Popular Scientific Works now in course of publication, consisting of popular and instructive works, on particular scientific subjects-Scientific Discovery, Applications, History, Biography-by some of the most eminent scientific men of the day. They will be so written as to be interesting and intelligible even to non-scientific readers. Mr. Lockyer's work in Spectrum Analysis is widely known. In the present short treatise will be found an exposition of the principles on which Spectrum Analysis rests, a description of the various kinds of Spectroscopes, and an account of what has already been done with the instrument, as well as of what may yet be done both in science and in the industrial arts. Roscoe (H. E.)—SPECTRUM ANALYSIS. Six Lectures, with Appendices, Engravings, Maps, and Chromolithographs. By H. E. ROSCOE, F.R.S., Professor of Chemistry in Owens College, Manchester. Third Edition, revised throughout. Royal "In six lectures he has given the history of the discovery and set forth the facts relating to the analysis of light in such a way that any reader of ordinary intelligence and information will be able to understand what Spectrum Analysis' is, and what are its claims to rank among the most signal triumphs of science of which even this century can boast."-NONCONFORMIST. "The illustrations-no unimportant part of a book on such a subject-are marvels of wood-printing, and reflect the clearness which is the distinguishing merit of Mr. Roscoe's explanations.”SATURDAY REVIEW. "The lectures themselves furnish a most admirable elementary treatise on the subject, whilst by the insertion in appendices to each lecture of extracts from the most important published memoirs, the author has rendered it equally valuable as a text-book for advanced students."-WESTMINSTER REVIEW. Thorpe (T. E.)—A SERIES OF CHEMICAL PROBLEMS, for use in Colleges and Schools. Adapted for the preparation of Students for the Government, Science, and Society of Arts Examinations.
