Two new works on the _Apocalypse_ are to be added to the immense number already printed, for New-York publishers. We not long ago undertook to ascertain how many expositions of the great mystery had been written in this country, and paused at the sixty-fifth title-page. One of the forthcoming works is an ingenious composition by the Rev. Mr. James of the western part of this state, and the other (to be published by Mr. Dodd) is by a clergyman in Connecticut. Longmans advertise in London _The Spiritual Exposition of the Apocalypse_, as derived from the writings of Swedenborg, and illustrated and confirmed by ancient and modern authorities, by the Rev. Augustus Clissold, of Exeter College; and the Rivingtons have in press a _Commentary on the Apocalypse_ by the Rev. ISAAC WILLIAMS, of Trinity College. England indeed is quite as prolific of such works as the United States. * * * * * MR. JOHN FINCHMAN, "master shipwright of her Majesty's Dockyard, at Portsmouth," has published a _History of Naval Architecture_, which is praised as a just exposition of the progress and supremacy of English ship-building. Our Mr. Collins could have furnished him, as illustrations for an additional and very interesting chapter, drawings of the _Pacific_ and the _Baltic_, which would perhaps make the work a "just exposition of the supremacy" of American ship-building, of which this Mr. Finchman seems never to have been informed. * * * * * Of collections of Letters on Affairs, that to be published immediately by Mr. Murray, under the title of the _Grenville Papers_, promises to be among the most important. It will comprise the Private Correspondence of Richard Grenville, Earl Temple, and his Brother, the Right Honorable George Grenville, and their friends and cotemporaries--formerly preserved at Stowe and now for the first time made public, and it is given out that it will contain material for the formation of a pretty conclusive judgment as to the authorship of Junius. * * * * * Among books that will bear a republication, if written with even average ability and fairness, is _The Present State of the Republic of the Rio de la Plata_ (_Buenos Ayres_), its Geography, Resources, Statistics, Commerce, Debt, etc. described, with the History of the Conquest of the Country by the Spaniards, by Sir WOODBINE PARISH, F.R.S. Formerly British Consul General and Chargé d' Affaires in that country. * * * * * LORD MAHON'S _History of England, from, the Peace of Utrecht_, volumes 5 and 6--the First Years of the American War: 1763 to 1780--was to appear in August. * * * * * A new book has just appeared in London on the Pitcairn's Islanders. * * * * *
