MISSIONARY ENTERPRISES.--Messrs. D. APPLETON AND COMPANY have published a handsome volume, of some five hundred pages, entitled 'A Narrative of Missionary Enterprises in the South Sea Islands; with Remarks upon the Natural History of the Islands, Origin, Languages, Traditions, and Usages of the Inhabitants. By JOHN WILLIAMS, of the London Missionary Society.' We regret that we are compelled to advert so briefly to this excellent work, in gathering the materials for which, the author travelled one hundred thousand miles, and expended upward of eighteen years. The book is full upon all the heads mentioned in its title, and is illustrated by numerous engravings on wood. The style is simple and flowing, and the details invariably interesting, not less to the general than the Christian reader. We were struck with a fact recorded toward the close of the volume, illustrative of that divine purpose in nature of which a correspondent elsewhere speaks, in the present number. In many of the coral islands of the South Sea, there are neither streams nor springs; and were it not for the cocoa-nut, the inhabitants would perish. On a sultry day, when the very ground burns with heat, the natives climb this fruit-tree, and in each unripe nut find a pint or more of a grateful lemonade-like water, as refreshing as if taken from a spring. 'SCIENCE MADE EASY:'--'Being a Familiar Introduction to the Principles of Chemistry, Mechanics, Hydrostatics, and Pneumatics.'--We took up this corpulent dictionary-quarto, under the impression that it was one of those scanty and superficial '_made-easy_' books, good-naturedly intended to instil dull truths into unwary understandings, by alternate layers of _utile_ and _dulce_, but capable in reality of very little good. Its perusal has agreeably disappointed us. The author has not alone skirmished on the frontier of a few of the sciences, but he has drawn a small array of them into close order, in such wise that they may be surveyed with ease and expedition, and made to fructify without a world of unnecessary trouble. The volume is illustrated by numerous wood-cuts. MISS LESLIE'S 'PENCIL SKETCHES.'--This volume contains all of Miss LESLIE's fugitive pieces which have appeared since the publication of her second series of 'Pencil Sketches.' Every article has been carefully revised by the author, and improved, as she believes, by numerous alterations and additions. The following are the contents: 'The Red Box, or Scenes at the General Wayne;' 'Constance Allerton, or the Mourning Suits;' 'The Officers, a Story of the Last War;' 'The Serenades, and Dream of Songs:' 'The Old Farm-House;' 'That Gentleman, or Pencillings on Ship-board;' 'Charles Loring, a Tale of the Revolution;' and 'Alphonsine.' Aside from the natural ease and conversational ability, peculiar to all Miss LESLIE's productions, the reader may always rely upon a main object of intellectual or moral good.
