NEW-YORK MERCANTILE LIBRARY ASSOCIATION.--We hear, with sincere pleasure, of the continued success and improvement of this widely-useful institution. A large increase of its already extended list of members; additions of new and valuable books; accessions of magazines, and the higher order of periodicals; and ample preparations for a series of lectures from some of the best minds of the country, are some of the more prominent indications of the 'high and palmy state' to which we have alluded. Let but party disaffections be religiously avoided--let the members but strengthen each other's hands in the advancement of the great interests of the association--and the institution, for whose original foundation we are mainly indebted to the benevolent efforts of WILLIAM WOOD, ESQ., of Canandaigua, will become one of which both our city and state may be justly proud. * * * * * LAPLACE.--We have received a small and handsomely-printed pamphlet, containing 'An Historical Eulogy of M. Le MARQUIS DE LAPLACE, pronounced in the Public Session of the Royal Academy of Sciences, at Paris, June 15, 1829. By M. Le BARON FOURIER, Perpetual Secretary.' Translated from the French, by R. W. HASKINS, ESQ., of Buffalo. We regard this as an excellent and compendious history of one of the most eminent scientific men France has ever produced. It is the tribute of a mind capable of appreciating the labors of one 'who enlarged the domain of thought, and taught man the dignity of his being, by unveiling to his view all the majesty of the heavens,' and whose name the world will not 'willingly let die.' A clear and forcible style assures us that the original has lost little in the hands of the translator. * * * * * *.* The reply of SAMUEL KIRKHAM, ESQ., to the extract from Mr. GOOLD BROWN's 'Grammar of English Grammars,' will appear in the October number. Having 'redeemed the time,' it may not be amiss to state, 'in this connection,' that the KNICKERBOCKER, will hereafter be issued with punctuality on the first of every month.
