A Practical Treatise on the Steam Engine, containing Plans and Arrangements of Details for Fixed Steam Engines, with Essays on the Principles involved in Design and Construction. By ARTHUR RIGG, Engineer, Member of the Society of Engineers and of the Royal Institution of Great Britain. Demy 4to, copiously illustrated with woodcuts and 96 plates, in one Volumé, half-bound morocco, 21. 25.; or cheaper edition, cloth, 25s. This work is not, in any sense, an elementary treatise, or history of the steam engine, but is intended to describe examples of Fixed Steam Engines without entering into the wide domain of locomotive or marine practice. To this end illustrations will be given of the most recent arrangements of Horizontal, Vertical, Beam, Pumping, Winding, Portable, Semiportable, Corliss, Allen, Compound, and other similar Engines, by the most eminent Firms in Great Britain and America. The laws relating to the action and precautions to be observed in the construction of the various details, such as Cylinders, Pistons, Piston-rods, Connectingrods, Cross-heads, Motion-blocks, Eccentrics, Simple, Expansion, Balanced, and Equilibrium Slide-valves, and Valve-gearing will be minutely dealt with. In this connection will be found articles upon the Velocity of Reciprocating Parts and the Mode of Applying the Indicator, Heat and Expansion of Steam Governors, and the like. It is the writer's desire to draw illustrations from every possible source, and give only those rules that present practice deems correct.

To ensure the correctness of these Tables of Logarithms, they were compared with Callett's, Vega's, Hutton's, Briggs', Gardiner's, and Taylor's Tables of Logarithms, and carefully read by nine different readers; and further, to remove any possibility of an error remaining, the stereotyped sheets were hung up in the Hall at Cambridge University, and a reward offered to anyone who could find an inaccuracy. So correct are these Tables, that since their first issue in 1827 no error has been discovered.

A SUPPLEMENT ΤΟ SPONS' DICTIONARY OF ENGINEERING, Cibil, Mechanical, Military, and Naval. EDITED BY ERNEST SPON, MEMB. Soc. Engineers. THE success which has attended the publication of 'SPONS' DICTIONARY OF ENGINEERING' has encouraged the Publishers to use every effort tending to keep the work up to the standard of existing professional knowledge. As the Book has now been some years before the public without addition or revision, there are many subjects of importance which, of necessity, are either not included in its pages, or have been treated somewhat less fully than their present importance demands. With the object, therefore, of remedying these omissions, this Supplement is now being issued. Each subject in it is treated in a thoroughly comprehensive way; but, of course, without repeating the information already included in the body of the work. The new matter comprises articles upon Abacus, Counters, Speed Indicators, and Slide Rule. Coal Mining. Coal Cutting Machines. Electric chines. Indicators. Iron. and Lifts, Hoists, and Eleva tors. Lighthouses, Buoys, and Machine Tools. Ores, Machinery and Piers. Pneumatic Transmis- Steel. Steam Navvy. Tramways. Well Sinking. With nearly 1500 illustrations, in super-royal 8vo, in 5 Divisions, cloth. Divisions I to 4, 135. 6d. each; Division 5, 17s. 6d. ; or 2 vols., cloth, £3 105.
