DR. SPRING, whose religious writings appear to be as popular in Great Britain as in this country, and every where to be regarded as among the classics of practical religious literature, has issued a second edition of his two octavos entitled _First Things_. In style, temper, and all the best qualities of such works, the discourses embraced in this work are deserving of eminent praise. (M. W. Dodd.) * * * * * Of HENRY MARTIN, whom the religious world regards with a reverent affection like that it gives to Cowper and Heber, the hitherto unpublished _Letters and Journals_ have just appeared, and they seem to us even more interesting than the so well-known Memoirs of his Life published soon after he died. (M. W. Dodd.) * * * * * MRS. SIGOURNEY has published a volume entitled _Letters to my Pupils, with Narrative and Biographical Sketches_. It embraces reminiscences of her experience as a teacher, and we have read none of her prose compositions that are more suggestive or more pleasing. (Robert Carter & Brothers.) * * * * * A _Life of Algernon Sydney_, by G. Van Santvoord (a new author), has been published by Charles Scribner. To describe the history and writings of this noble republican was a task worthy of an American scholar. Mr. Van Santvoord has performed it excellently well. * * * * * BAYARD TAYLOR and R. H. STODDARD have new volumes of poems in the press of Ticknor, Reed & Fields, of Boston, and that house has never published original volumes of greater merit, or that will be more popular. * * * * * THE POEMS OF WILLIAM P. MULCHINOCK, in one volume, lately published by Mr. Strong, Nassau-street, appear to have been received with singular favor by the critics. Mr. Mulchinock has remarkable fluency, and a genial spirit. His book contains specimens of a great variety of styles, and some pieces of much merit. * * * * * TICKNOR & CO. have published a novelette entitled _The Solitary_, by Santaine, the author of "Picciola." It is of the Robinson Crusoe sort of books--better than any other imitation of Defoe. * * * * * The _Pocket Companion, for Machinists, Mechanics, and Engineers_, by OLIVER BYRNE, is a remarkable specimen of perspicuous condensation. In a beautiful pocket-book it embraces for the classes for whom it is designed the pith of two or three ordinary octavos. * * * * * Among the new volumes of poems is one of Dramatic and Miscellaneous Pieces, by CHARLES JAMES CANNON, published by Edward Dunigan. Mr. Cannon is a writer of much cultivation, and, in his dramatic poems, especially, there are passages of much force and elegance. * * * * *
