The Mastery Series: for Learning Languages on a New Principle. By THOMAS PRenderGAST, late of the Madras Civil Service, Author of The Mastery of Languages, or the Art of Speaking Foreign Tongues Idiomatically.' 12mo. [January 22, 1868.

I. HANDBOOK to the MASTERY SERIES, pp. 92, price 1s. cloth.

II. The MASTERY SERIES, GERMAN, pp. 102, price 1s. 6d. cloth.

III. The MASTERY SERIES, FRENCH, pp. 118, price 1s. 6d. cloth.

To be followed shortly by— IV. The MASTERY SERIES, HEBREW, price 1s. 6d. THE objects of the Mastery method are to en

able the beginner to pronounce a foreign language correctly, and to speak it idiomatically, from the outset. In the Author's belief, it secures

economy of time and labour; assists the memory, so that it retains all that has been learnt; tends to produce perfect fluency and accuracy in the daily reproduction of all the previous lessons; and never permits a new lesson to be undertaken except on the fulfilment of that condition.

The study of grammar is postponed, and the beginner is not allowed to compose any exercises at first. He learns nothing but idiomatic sentences, and as he learns them very thoroughly, he can scarcely fail to speak idiomatically and grammatically also.

The lessons are short, but great results are obtained by evolving numerous variations from the sentences committed to memory. Each variation is also a complete colloquial sentence, containing some words with which the beginner is already familiar. The English versions thereof are to be translated by him from memory in regular succession thrice a-day, and this constitutes the whole process.

Short and concentrated efforts of memory are substituted for close and protracted application. The method is well adapted for self-instruction, and the German Manual' shews the mode of applying it to Greek and Latin as an initiatory process to precede the study of grammar.

A Collective Edition of the Rev. G. W. Cox's Classical Stories and Tales, is preparing for publication, complete in One Volume, intitled The Gods and 'Heroes.' This work will comprise all the tales published in the separate volumes, intitled severally Tales from Greek Mythology,' Tales of the Gods and Heroes,' and 'Tales of Thebes and Argos.' The stories have been so arranged as to present the legends in their natural sequence, so far as the term may be applied to a mythology which was not developed by system. The legends of the gods are followed by those of the heroes, and of their exploits in the Argonautic and other expeditions and in the war at Troy. As a whole, they may be regarded as containing the main substance of all Greek mythology. The introductions to the Tales of the Gods and Heroes and the Tales of Thebes and Argos are omitted in the collected edition; but a new preface is prefixed, in which the origin and growth of each myth are briefly traced.

A Series of Penny Tracts, intitled Notes on the Faith,' is preparing for publication.

'The Laws of Thought,' by ALEXANDER ROBERTSON, Author of The Philosophy of the Uncon'ditioned.' The Third Edition of this work, greatly extended, will be ready in April.-The Writer, taking the existence of GoD as an axiom, proceeds after the manner of the geometricians to demonstrate some of the great and necessary conclusions evolvable therefrom. He shews that not only is this a correct method of philosophising, but that it must be the law of all thought. The Author contends that this system is substantially that of PLATO, DESCARTES, COUSIN, and the Scottish school, as opposed to ancient and modern materialistic Sensationalism.

M'CULLOCH'S COMMERCIAL DICTIONARY.-In the press, A Dictionary, Practical, Theoretical, and Historical, of Commerce and Commercial Navigation.' By the late J. R. M'CULLOCH, of H.M. Stationery Office. New Edition, revised throughout and corrected to the Present Time by JAMES E. THOROLD ROGERS, M.A. sometime Professor of Pol. Econ. in the Univ. of Oxford, and Tooke Professor of Economic Science and Statistics in King's College, London; and W. M. BUCKNALL, Esq. of Her Majesty's Board of Trade.

New Work by ELIJAH WALTON, F.G.S.Early in March will be published, in Quarto, price 638. Clouds, their Forms and Combinations.' By ELIJAH WALTON, F.G.S. Author of The Camel,' &c. During several years spent abroad, the Author of this work has devoted special attention to the forms and combinations of clouds. The PHOTOGRAPHS which will compose the volume now announced are being prepared from the original drawings, which were made with the utmost care. Being printed in carbon and therefore permanent, they will, it is hoped, be found useful and instructive to artists and to the public in general. The volume will consist of 46 Plates of Clouds as seen from Upper and Lower Egypt, Syria, Arabia, Constantinople, Italy, the Swiss Alps, and other parts of the Eastern Hemisphere, with DESCRIPTIVE TEXT.

OPPEN'S GERMAN CLASSICS.--Preparing for publication, a new Annotated Edition of German Classics, containing Historical Introductions, Critical Notices, &c. by EDWARD A. OPPEN, of Haileybury College. This Series will consist of some of Goethe's, SCHILLER'S, and LESSING'S Plays, three of which, viz. 'Egmont, Wilhelm Tell,' and 'Minna Von Barnhelm, are in the press. To be followed by Iphigenie,' ' Don Carlos,' and Nathan Der Weise.' The system of annotation in this Series will be somewhat different from that adopted by former Editors. All superfluous matter has been discarded, and greater care bestowed upon the historical and idiomatic portion. The price of all these Plays will be fixed so low, that the Publishers hope to supersede all foreign-printed and other editions.

New French Grammar and Exercise Book by F. TARVER, M.A.-Preparing for publication, in 12mo. in Two Parts, The Eton French Grammar and 'Exercise Book.' By F. TARVER, M.A. Oxon. Assistant French Master at Eton College. The work now announced is entirely new. The Author's object, after nearly five years' experience as teacher of French at Eton, where that language is permanently introduced into the regular course of studies, has been to present within the limits of a single manual, in Two Volumes of convenient compass, all that is required for classteaching in Public Schools, both as a Grammar for reference and Exercises for practice. The FIRST Part, containing the Accidence and Verbs, with graduated exercises upon them, will be ready early in March. The SECOND PART, containing the Syntax-rules and more advanced Exercises, will follow shortly.

Dr. ZELLER's Works on SOCRATES and the SOCRATIC SCHOOLS and on ARISTOTLE and the ELDER PERIPATETICS.-An English Translation of both these works is preparing for publication: that on Socrates and the Socratic Schools by OsWALD J. REICHEL, B.C.L. and M.A. Vice-Principal of Cuddesden College; that on Aristotle and the Elder Peripatetics by JOHN ADDINGTON SYMONDS, M.A. late Fellow of Magdalen College, Oxford. The portion of Dr. ZELLER's work on the Philosophy of the Greeks, which treats of SOCRATES and the Socratic schools, has been selected in the hope of meeting a want, frequently felt, of a single book containing some account of the immediate philosophical antecedents of PLATO and ARISTOTLE. In the volume on Socrates and the Socratic Schools,' a complete and at the same time a concise account of the antecedents of PLATO and ARISTOTLE, by one of the most eminent historical students of Germany, is placed before the English reader. The want still felt in our Universities of a good general exposition of the Aristotelian philosophy will, it is hoped, be met by the publication of that portion of Dr. ZELLER's work which treats of this subject. The two volumes may be regarded as forming one coherent work, but either volume forms a treatise complete in itself. It is thought that no other work of the same compass is so well fitted to meet all the wants of students in our Universities.

'An Introduction to the Study of the New Testa'ment, Critical, Exegetical, and Theological,' is preparing for publication by the Rev. S. DAVIDSON, Ú.D. LL.D. to form Two Volumes, 8vo. This work will contain a discussion of all important questions respecting the origin, authenticity, date, object, plan, and peculiarities of the separate books; endeavouring to present the settled results which the best criticism has arrived at, and in which varying views are likely to acquiesce at last. It is adapted to all classes of readers and students, to the intelligent laity as well as the clergy, by avoiding the use of Greek and Latin words in the text, as far as possible, and inserting them in notes. For the sake of readers unacquainted with other languages, an English translation is given wherever it has been thought desirable or necessary.

A volume of 'Illustrations of Children's Diseases,' by CHARLES WEST, M.D. F.R.C.P. Physician to the Hospital for Sick Children,-is preparing for publication. The duty of a teacher of Practical Medicine is to familiarise an unskilled audience with the general characters of disease, to point out common errors, to lay down usual modes of treatment. To do this was the Author's endeavour in his Lectures on the Diseases of Infancy and Childhood. But there remains a large number of exceptional cases, of unusual difficulties, of debateable questions, on which the experience of years may fairly be expected to throw some light. The object of the ILLUSTRATIONS now announced will therefore be to supplement the Author's Lectures. They are intended for the practitioner as well as for the student, and are designed to shew the less common forms and varieties of disease, as well as to help towards the decision of those difficulties of diagnosis and treatment whose importance must not be measured by the comparative rarity of their occurrence.
