SPEECHES from THUCYDIDES, translated into English for the use of Students, with an Introduction and Notes, by HENRY MUSGRAVE WILKINS, M.A. Fellow of Merton College, Oxford, will be ready early in the spring, in One Volume, 8vo. - This volume is chiefly designed for the use of Candidates for Classical Honours at our Universities and Public Schools. With this view, the version has been modelled on the style of translation encouraged in the Honour Schools of Oxford and Cambridge; a style close but thoroughly idiomatic, yet sufficiently free to satisfy the taste of the general reader. It may safely be said that, among the many translations of THUCYDIDES, there is none which answers this purpose. The field is occupied solely by the solemn pedantry of BLOOMFIELD, the grotesque likeness of HOBBES, the hideous fidelity of DALE, and the spirited but truant paraphrase of CRAWLEY, which comprises the first book only. Mr. DALE's version, though in many respects useful, is not always a safe guide, even for passmen, for whom it is intended. A purely literal rendering of so difficult an author often deepens the obscurity of the original; besides, the meaning, as is shewn in the Preface to the forthcoming work, is frequently vitiated by mistranslations of the particles; yáp, for instance, being constantly taken in an argumentative when it has an epexegetic or inchoative sense. The text of POPPO's smaller edition has been

generally followed. The marginal notes have been limited, with few exceptions, to the necessary defence of the choice which has been made between contested versions of difficult passages. The illustrations of the particles, which are so puzzling to the student of THUCYDIDES, had the advantage of revision by the late Professor CONINGTON, and are based, for the most part, on the valuable Commentary of KLOTZ on DEVARIUS, Leipsic, 1840-a work as precious as it is scarce. The Introduction is divided into two chapters, the first of which discusses the chief difficulties which beset the translator of THUCYDIDES. The second is devoted to an examination of the Speeches, with a view especially to the purposes they serve in relation to the history. The chief editions upon which the version has been based are those of KRÜGER (German), 1860; Dr. ARNOLD, Oxford, 1830-1835; GÖLLER'S Second Edition, Leipsic, 1836; the Larger Edition of PoPro, 10 vols., Leipsic, 1821-1838; and the Smaller one in 4 vols., Leipsic, 1816-1866.

SUPPLEMENT to WATTS'S DICTIONARY of CHEMISTRY.-Two years have now elapsed since this Dictionary was completed, and nine years since the first volume was printed; and during these years large and important additions have been made both to the facts and to the theories of Chemical science. To present these additions in a compendious form, it has been thought desirable to publish a SUPPLEMENT to the Dictionary, bringing the record of Chemical discovery down to the end of the year 1869. This SUPPLEMENT will form a volume of about 800 pages, and is expected to be ready in October next. AUTHOR has been fortunate in securing the cooperation of several of his former CONTRIBUTORS, who have kindly consented to furnish additions to their articles.

The

New Edition of Sir W. FAIRBAIRN'S Work on IRON-In the press, in 1 vol. 8vo. with Plates and Woodcuts, The Application of Cast and Wrought Iron to Building Purposes.' By SIR WILLIAM FAIRBAIRN, Bart. C.E. LL.D. F.R.S. &c. Fourth Edition, thoroughly revised, with Additions. The Edition now announced will contain an extended series of experiments on TRUSSED BEAMS, shewing the comparative value of wood and cast iron in that form. To these have been added an experimental enquiry into the durability of wrought iron beams and girders, with a view to determine the force of impact and the influence of a series of changes with variable loads. These researches are of high importance as a safeguard to the amount of load or strain to which beams and girders may be subjected. In an APPENDIX will be given the results of certain experimental researches on the properties of STEEL and HOMOGENEOUS IRON, as used in architecture, building, and engineering.
