The Lana' Improver's Pocket-Book. By John Ewart. (Lockwood and Co.)—This

is a compendious and handy little volume, in note-book shape, consisting of formulas, tables, and memoranda required in any computation relating to the permanent improvement of landed pro- perty. The author intends it to supply the same portable reference to- calculations required by land agents as that supplied by Molesworth's books for the use of civil and mechanical engineers, by Hurst's books for architects, and many others. Mr. Ewart's compilation seems to us to be admirably arranged, and can hardly fail to prove exceedingly useful to the class of professional men for whom it is intended.
