A Handbook of Formulæ, Tables, and Memoranda, for Architectural Surveyors and others engaged in Building. By J. T. Hurst, C.E. Thirteenth edition, royal 32mo, roan, 5s.

“It is no disparagement to the many excellent publications we refer to, to say that in our opinion this little pocket-book of Hurst’s is the very best of them all, without any exception. It would be useless to attempt a recapitulation of the contents, for it appears to contain almost everything that anyone connected with building could require, and, best of all, made up in a compact form for carrying in the pocket, measuring only 5 in. by 3 in., and about ¾ in. thick, in a limp cover. We congratulate the author on the success of his laborious and practically compiled little book, which has received unqualified and deserved praise from every professional person to whom we have shown it.”—The Dublin Builder.
