"The Museum of Science and Art is the most valuable coutribution that has ever been made to the scientific instruction of every class of society."- Sir David Brewster, in the North British Review. "This series, besides affording popular but sound instruction on scientific subjects, with which the humblest man in the country ought to be acquainted, also undertakes that teaching of Common Things' which Lord Ashburton and every well-wisher of his kind are anxious to promote. Many thousand copies of this serviceable publication have been printed, in the belief and hope that the desire for instruction and improvement widely prevails; and we have no fear that such enlightened faith will meet with disappointment "-Times, Feb. 9, 1854. "This serial, which will form quarterly eighteenpenny volumes, is, we are disposed to think, the best literary investment of a penny a week now extant.-Examiner. "A cheap and interesting publication, alike informing and attractive. The papers combine subjects of importance and great scientific knowledge, considerable inductive powers, and a popular style of treatment."-Spectator. *Hand-Book of Mechanics.

THE above Four Volumes taken together form a complete course of Natural Philosophy (Price 20s.) sufficient not only for the highest degree of School Education, but for that numerous class of University Students who, without aspiring to the attainment of Academic honours, desire to acquire that general knowledge of these Sciences which is necessary to entitle them to graduate, and, in the present state of society, expected in all well-educated persons. It is also intended for the general reader who desires to attain accurate knowledge of the various departments of physical science, without pursuing them according to the more profound methods of Mathematical investigation. Great pains have been taken to render this work complete in all respects, and co-extensive with the actual state of the sciences, according to the latest discoveries. The present edition has been enlarged by the interpolation of a great number of illustrations of the general principles of Physics, taken from their various applications in the Arts, such examples being in all cases elucidated by appropriate engraved figures of the instruments and machines described. * Dr. Lardner's Hand-Book of Astronomy and Meteorology, forming a companion work to the "HAND-BOOK OF NATURAL PHILOSOPHY." With 37 Plates, and upwards of 200 Illustrations on Wood. 2 vols., each 5s., cloth lettered. THE treatise on ASTRONOMY embraces, among a vast mass of important and interesting matter classed under the usual heads, all the most recent discoveries made by means of the improvement of the telescope. It describes all the best methods of celestial observation, and gives particular explanations of the instruments used in an observatory. It gives a complete history of the phenomena which led to the simultaneous researches of Le Verrier and Adams, resulting in the wonderful discovery of the planet Neptune. Graphic illustrations have been unsparingly supplied. *Natural Philosophy for Schools. By Dionysius LARDNER, D.C.L. 328 Illustrations. 1 vol. Large 12mo. 3s. 6d. cloth. THIS Volume has been compiled to supply the want felt by a large number of teachers in public and private schools of a Class Book for Junior Students. Its purpose is to convey, in clear and concise terms, general notions of all the principal divisions of Physical Science, illustrated copiously by diagrams, showing the forms and arrangement of apparatus, and the manner of performing the most important experiments. Each of the subjects briefly explained here is fully developed in all its details, and more amply illustrated, in the corresponding parts of the "Hand-Book of Natural Philosophy," which should always be in the hands of the teacher, who, by oral instruction, will then be enabled to develop each point, and illustrate it more or less fully, according to the capacity of the pupil. It may be hoped, that this volume may be the means of extending instruction in the first notions of Physics into Ladies' Schools. Female teachers in general will find even the Hand-Book easily intelligible, and by it will be enabled to use the present volume for the instruction of their pupils. The Table of Contents is so composed, that the teacher can form from it questions for the examination of his Class, the Answers to which will be found in the corresponding paragraphs of the volume.

Formal Logic. cessary and Probable. LOGIC. Or, The Calculus of Inference, NeBy AUGUSTUS DE MORGAN, Professor of Mathematics in University College, London. 8vo. 6s. 6d. THE first chapter of this work (First Notions) is an elementary introduction to ordinary logic, which first appeared in a separate form. With the second chapter, On Objects, Ideas, and Names; part of the seventh, On the Aristotelian Syllogism; part of the eleventh, On Induction; the twelfth, On old Logical Terms; and the thirteenth, On Fallacies-it forms a work on ordinary logic, independent of the rest. The remainder of the work is devoted to the development of two new views. The first, that in which contrary terms are considered as formally admissible, and all modes of predication are adopted, whether the terms be the terms of the conclusion, or their contraries. The second, in which the proposition is made numerically .definite, the number of instances of which affirmation or denial is made, taking the place of the all or some of the ordinary logical proposition. All cases in which inference can be made are demonstratively collected, and the particular cases which form the ordinary system of syllogism are shown to be contained in the system. Two chapters are devoted to the explanation of probability, and its mathematical application to questions of probable inference. The new matter which this work contains is pointed out by italics in the Table of Contents. In an Appendix is contained the author's final reply to the charges made against him by Sir William Hamilton, of Edinburgh. An Investigation of the Laws of Thought, on which are founded the Mathematical Theories of Logic and Probabilities. By GEORGE BOOLE, LL.D., Professor of Mathematics in Queen's College, Cork. 8vo. 148. cloth. THE design of this treatise is to investigate the fundamental laws of those operations of the mind by which reasoning is performed; to give expression to them in the symbolical language of a Calculus, and upon this foundation to establish the science of logic and construct its method; to make that method itself the basis of a general method for the application of the mathematical doctrine of probabilities; and, finally, to collect from the various elements of truth brought to view in the course of these inquiries, some probable intimations concerning the nature and constitution of the human mind. The work consists of a system of logical processes carried on by the aid of symbols nearly analogous to those of Algebra. Thus, the letters x, y, etc., are made to represent things as subjects of our conceptions; the characters +, -, x, are used as signs of operation by which the conceptions of things are combined or resolved, so as to form new conceptions involving the same elements. The sign indicates identity, and the laws of thought are expressed by equations. The laws of these symbols of logic are deduced from a consideration of those operations of the mind which are implied in the strict use of language as an instrument of reasoning. An original feature in this work is, that it regards the subject of probabilities as belonging equally to the science of number and that of logic; and by the combination of both elements, it professes to resolve problems in probabilities more generally than is otherwise practicable. Among the more interesting examples of this symbolical method of argumentation, is an analysis, by translation into symbols, of Dr. Samuel Clarke's "Demonstration of the Being and Attributes of God." * The Art of Reasoning: a Popular Exposition of the Principles of Logic, Inductive and Deductive; with an Introductory Outline of the History of Logic, and an Appendix on recent Logical Developments, with Notes. By SAMUEL NEIL. Crown 8vo. 4s. 6d. cloth. THE aim of the author, in this publication, has been to combine the advantages of a popular exposition of the subject with the rigour of purely formal or abstract treatises. |
