The volume--which contains 118 printed pages, besides a few blank pages for memoranda--is, in fact, a true pocket-book, adapted for being carried in the waistcoat pocket, and containing a far greater amount and variety of information than most people would imagine could be compressed into so small a space. … The little volume has been compiled with considerable care and judgment, and we can cordially recommend it to our readers as a useful little pocket companion.”--_Engineering._

It is not difficult to take a diagram if the instrument is once set, and the setting with stationary engines is occasionally easy enough, but circumstances continually arise under which the young engineer is completely at a loss as to how to obtain a diagram. All uncertainty will be removed by referring to the book under consideration: here we have drawings of the arrangements to be adopted under every conceivable circumstance, drawings, we may add, illustrating the practice of the best engineers of the day.”--_Engineer._

_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 Volume, half-bound morocco, 2_l._ 2_s._; or cheaper edition, cloth, 25_s._

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, Connecting-rods, 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.
