Drawing and Engraving : a Brief Exposition of Technical Principles

and Practice. By Philip Gilbert Hamerton.. With numerous illustrations. (Adam and Charles Black.)=—This is a reprint of two articles by Mr. Hamorton in the "Encyclopedia Britannica," and will be found a useful general introduction to the subjects it• treats. Mr. Hamerton's clear and easy style makes technical pro- cesses intelligible to the inexpert. It would be easy to criticise many of the statements made, and to point out omissions, but it would be difficult to name any one book which does the same work so well.
