Abstract
THIS very unpretentious but very useful little manual has reached a second edition, and now reappears with several valuable additions. In his original preface the author states that he does not expect an electrician to discover anything new in its pages. Be that as it may, the electrician will acknowledge the debt he owes to Capt. Hoskiaer for the precision and brevity with which all his directions concerning the practical details of testing are given. Without philosophising or going into mathematical reasons of why and wherefore, he gives the necessary formulæ in the shape most useful for practical calculations; and the necessary tables of logarithms, trigonometrical functions, and temperature coefficients are sufficiently complete to save reference to other more extended works. The twelve lithographed diagrams leave nothing to be desired in point of clearness.
