In the Press, and shortly will be Published:

A COURSE OF MATHEMATICS;

DESIGNED

FOR CIVIL ENGINEERS, THOSE INTENDED FOR THAT PROFESSION, AND PRACTICAL MEN.

This will be the most practical as well as the most extensive Course of Mathematics ever published. The examples will be chiefly practical, and taken from actual experience: including the calculations on the steam-engine and railroads; with those on embankments, cuttings, strength of materials, pressure of earth, bridges, tunnels, steam navigation, naval architecture, and every subject connected with Engineering, in all its various departments. Also, the most useful examples in NAVIGATION, FORTIFICATION, Land SurVEYING, LEVELLING, &c.

The work will be complete in itself, with no reference to other books. All the rules will be so illustrated, and the operations so explained, that those of an ordinary capacity can acquire mathematics without the aid of a teacher.

ON BRIDGES, VAULTS, AND ARCHES,

UNIFORM WITH THE SPLENDID WORK ON

HARBOURS, BY SIR JOHN RENNIE.

Mr. WILLIAMS, in announcing the completion of the above valuable Work, begs to return his most grateful thanks to more than 500 Subscribers, who have so generously patronized this National Publication, and who, in defiance of the unavoidable delays which have occurred, have continued their considerate kindness down to the present moment; it will now be his most anxious desire to evince his gratitude for these favours, by rapidly completing the Volume, in a style worthy of the name of RENNIE, and the other eminent Men, whose works are embodied in its pages. All the Subscribers who have the 1st and 2nd parts are earnestly desired to claim the 3rd and 4th parts, which will finish the Volume.

The Subscribers are entitled to the 3rd and 4th parts, including Letter-press, for £2 28., making the whole work £4 4s., as originally advertised to Subscribers, but the price, when completed, will be £5 5s. to Non-Subscribers; which will even then, considering the originality and varied importance of the contents-the beauty of the engravings-and the style of the getting-up-be the cheapest Engineering Work yet Published.

N.B.-The Subscribers are solicited to claim the 3rd and 4th parts as quickly as possible, so that Mr. Williams may forward every one on the day of publication.

Opinions of the Press.

"We hail with pleasure the appearance of this work on Bridges, which is got up with great care, and with numerous plates, beautifully and clearly engraved. The first part, now before us, contains Twenty Plates, which will be found of great value both to the Architect and the Engineer. "The first series relates to London Bridge, constructed by Sir John Rennie, a work with which we know no other that can stand in comparison, except, perhaps, Waterloo Bridge. It is a monument indeed equally interesting from its grandeur, the boldness of the span of the arch, the simplicity of its style, and the durability of the materials; one which must command admiration in future ages, to as great a degree as it does now. It is interesting, no less from its own merits, than as a triumph over the obstacles which it had to overcome.

"The drawings consist of the plan, elevation, and section, drawn to a small scale; and of the coffer-dam, section, and centre of one of the arches: the elevation of the centre arch and section and plan of an abutment drawn to a scale of 12 feet to 1 inch. The appearance of the second part fully maintains the high character promised by the first."-Civil Engineer and Architect's Journal. The Reviews (Foreign and English) have uniformly praised this Standard Work.

Notices of the Press.

"The number of this month is devoted to the building of prisons, a subject rendered of increased importance to architects and the public, by the late reports to Parliament of the Prison Inspectors. Many sound suggestions on the subject, and an immense amount of detail, in the form of estimates, &c., connected with their erection, and the building of Spilsby Court-house are given, all of which must be of immense advantage to parties practically engaged in the business."-Argus.

"The entire body of the profession are indebted to the able Editor of this work."-Argus. "The object of this publication is to collect together a mass of valuable documents and illustrations on architectural practice, which hitherto have existed in a loose and divided state, and to place before the professor, the student, and the amateur, a library of professional reference of considerable value and importance. The value of a work of this description depends on the manner of its execution and arrangement. Both these appear unexceptionable, and we consider these Architectural Precedents' worthy a place in the library of every professor, student, and ama

teur."-Inventor's Advocate.

Mr. Loudon says, "it will be very useful to students and amateurs."

"It is copious, minute, well arranged, and got up with attention to its practical utility."Weekly Dispatch.

"This work is valuable for its architectural directions, and (the 4th part) for its abridgement of the 4th Report of the Inspectors of Prisons, which popular and important subject it copiously and clearly illustrates."-Atlas, July 4, 1840.

"This professes to be A thorough practical work on specifications, quantities, and working drawings of buildings and other public edifices,' and, so far as we can judge from the number before us, is likely to fulfil the promise. The tables, sections, and elevations, cannot but be extremely useful both to the professional builder and to private individuals. This number relates exclusively to domestic architecture, and illustrates the mode of constructing houses of moderate dimensions, of which it contains all the materials for specifications and estimates. The plan will be extended to shop-fronts, manufactories, and every variety of building, public or private, the whole expressly arranged for the reference of architects, engineers, builders, clerks of works, and professional students."-Liverpool Paper.

In one handsome 4to Volume, with nearly 80 Large Plates, elegantly and correctly engraved on Steel; also, a splendid Frontispiece of the celebrated Maidenhead Bridge, renowned throughout Europe for its beautiful construction.
