Wrinkles in Electric Lighting Part 5

_Spons' Tables and Memoranda for Engineers_; selected and arranged by J.

T. HURST, C.E., Author of 'Architectural Surveyors' Handbook,' 'Hurst's Tredgold's Carpentry,' etc. Ninth edition, 64mo, roan, gilt edges, 1_s._; or in cloth case, 1_s._ 6_d._

This work is printed in a pearl type, and is so small, measuring only 2-1/2 in. by 1-1/4 in. by 1/4 in. thick, that it may be easily carried in the waistcoat pocket.

"It is certainly an extremely rare thing for a reviewer to be called upon to notice a volume measuring but 2-1/2 in. by 1-1/4 in., yet these dimensions faithfully represent the size of the handy little book before us. 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 s.p.a.ce.... 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._
