As good a volume for the instruction of the pupil or student of iron naval architecture as can be found in any language."-Practical Mechanics' Journal. "A very elaborate work. It forms a most valuable addition to the history of iron shipbuilding, while its having been prepared by one who has made the subject his study for many years, and whose qualifications have been repeatedly recognised, will recommend it as one of practical utility to all interested in shipbuilding."-Army and Navy Gazette.

"Tredgold's Carpentry' ought to be in every architect's and every builder's library, and those who do not already possess it ought to avail themselves of the new issue."-Builder. "A work whose monumental excellence must commend it wherever skilful carpentry is concerned. The Author's principles are rather confirmed than impaired by time, and, as now presented, combine the surest base with the most interesting display of progressive science. The additional plates are of great intrinsic value.”—Building News. "Tredgold's Carpentry' has ever held a high position, and the issue of the fifth edition, in a still more improved and enlarged form, will give satisfaction to a very flarge number of artisans who desire to raise themselves in their business, and who seek to do so by displaying a greater amount of knowledge and intelligence than their fellow-workmen. It is as complete a work as need be desired. To the superior workman the volume will prove invaluable; it contains treatises written in language which he will readily comprehend."-Mining Journal.

"Everything it pretends to be: built up gradually, it leads one from a forest to a treenail, and throws in, as a makeweight, a host of material concerning bricks, columns, cisterns, &c.—all that the class to whom it appeals requires."-English Mechanic. "The only difficulty we have is as to what is NOT in its pages. What we have tested of the contents, taken at random, is invariably correct."-Illustrated Builder's Journal, Tables for Packing-Case Makers. PACKING-CASE TABLES; showing the number of Superficial "Will save much labour and calculation to packing-case makers and those who use packing-cases."-Grocer.

Also a variety of other valuable information. By WILLIAM DOWSING, Timber Merchant. Second Edition. Crown 8vo, 3s. cloth. "Everything is as concise and clear as it can possibly be made. doubt that every timber merchant and builder ought to possess it, because such possession would, with use, unquestionably save a very great deal of time, and, moreover, ensure perfect accuracy in calculations. There is also another class besides these who ought to possess it; we mean all persons engaged in carrying wood, where it is requisite to ascertain its weight. Mr. Dowsing's tables provide an easy means of doing this. Indeed every person who has to do with wood ought to have it."-Hull Advertiser. There can be no MECHANICS, &c. Mechanic's Workshop Companion. COM THE OPERATIVE MECHANIC'S WORKSHOP II Plates. 12mo, 5s. bound. "As a text-book of reference, in which mechanical and commercial demands are judiciously met, TEMPLETON'S COMPANION stands unrivalled."-Mechanics' Magazine. "Admirably adapted to the wants of a very large class. It has met with great success in the engineering workshop, as we can testify; and there are a great many men who, in a great measure, owe their rise in life to this little work."-Building News. Engineer's Assistant. THE ENGINEER'S, MILLWRIGHT'S, and MACHINIST'S Matter, by W. TEMPLETON. 4th Edition. 18mo, 2s. 6d. cloth. "So much varied information compressed into so small a space, and published at a price which places it within the reach of the humblest mechanic, cannot fail to command the sale which it deserves. With the utmost confidence we commend this book to the attention of our readers."-Mechanics' Magazine. "Every mechanic should become the possessor of the volume, and a more suitable present to an apprentice to any of the mechanieal trades could not possibly be made." -Building News. Designing, Measuring, and Valuing. THE STUDENT'S GUIDE to the PRACTICE of MEA- "This useful book should be in every architect's and builder's office. It contains a vast amount of information absolutely necessary to be known."-The Irish Builder. "The book is well worthy the attention of the student in architecture and surveying, as by the careful study of it his progress in his profession will be much facilitated."Mining Journal. "We have failed to discover anything connected with the building trade, from excavating foundations to bell-hanging, that is not fully treated upon in this valuable work." -The Artizan. "Mr. Tarn has well performed the task imposed upon him, and has made many further and valuable additions, embodying a large amount of information relating to the technicalities and modes of construction employed in the several branches of the building trade. From the extent of the information which the volume embodies, and the care taken to secure accuracy in every detail, it cannot fail to prove of the highest value to students, whether training in the offices of provincial surveyors, or in those of London practitioners."-Colliery Guardian. "Altogether the book is one which well fulfils the promise of its title-page, and we can thoroughly recommend it to the class for whose use it has been compiled. Mr. Tarn's additions and revisions have much increased the usefulness of the work, and have especially augmented its value to students. Finally, it is only just to the publishers to add that the book has been got up in excellent style, the typography being bold and clear, and the plates very well executed."-Engineering.

YOUNG, formerly Profes sor of Mathematics, Belfast College; Author of "A Course of Mathematics," &c. With 13 Plates. Medium 8vo, 17. Is. cloth. "As a standard work on mathematics it has not been excelled."-Artizan. "The engineer or architect will here find ready to his hand, rules for solving nearly every mathematical difficulty that may arise in his practice. As a moderate acquaintance with arithmetic, algebra, and elementary geometry is absolutely necessary to the proper understanding of the most useful portions of this book, the author very wisely Las devoted the first three chapters to those subjects, so that the most ignorant may be enabled to master the whole of the book, without aid from any other. The rules are in all cases explained by means of examples, in which every step of the process is clearly worked out."-Builder. "One of the most serviceable books to the practical mechanics of the country.. The edition of 1847 was fortunately entrusted to the able hands of Mr. Law, who revised it thoroughly, re-wrote many chapters, and added several sections to those which had been rendered imperfect by advanced knowledge. On examining the various and many improvements which he introduced into the work, they seem almost like a new structure on an old plan, or rather like the restoration of an old ruin, not only to its former substance, but to an extent which meets the larger requirements of modern times. In the edition just brought out, the work has again been revised by Professor Young. He has modernised the notation throughout, introduced a few paragraphs here and there, and corrected the numerous typographical errors which have escaped the eyes of the former Editor. The book is now as complete as it is possible to make it. We have carried our notice of this book to a greater length than the space allowed us justified, but the experiments it contains are so interesting, and the method of describing them so clear, that we may be excused for overstepping our limit. It is an instructive book for the student, and a Textbook for him who having once mastered the subjects it treats of, needs occasionally to refresh his memory upon them."-Building News. The Metric System. A SERIES OF METRIC TABLES, in which the British "Mr. Dowling's Tables, which are well put together, come just in time as a ready reckoner for the conversion of one system into the other."-Athenæum. "Their accuracy has been certified by Professor Airy, the Astronomer Royal."Builder. "Resolution 8.-That advantage will be derived from the recent publication of Metric Tables, by C. H. Dowling, C.E."-Report of Section F British Association, Bath. |
