EXPEDITIONS OF DISCOVERY.

Narratives of these important and interesting enterprizes multiply so fast, that we are happy to announce, as preparing for publication, a series of abstracts of the most recent Voyages and Overland Journeys. They will be printed in an economical volume adapted to all classes of purchasers, and will contain all the new facts in nautical and geographical science; details of the Natural History of the respective countries, the manners and customs of the natives, &c.—Fernando Po, Timbuctoo, Clapperton's African adventures, and Capt. Dillon's discoveries relative to the fate of La Perouse, will, of course, form prominent portions of this work, the popular title of which will be, "The Cabinet of Recent Voyages and Travels."
