Prof. AGASSIZ, the celebrated Naturalist, is making a survey of the Florida reefs and keys, in the hope that he may throw some light upon their formation and growth. He is nominally attached to the Coast Survey. American scholars still continue their valuable contributions to classical learning. Prof. DRISLER, of Columbia College, one of the most thorough and accurate linguists in the country, is engaged upon an _English-Greek Lexicon_, which will be a most valuable aid to the classical student, in connection with similar works by the same author hitherto issued. In the departments of religious and theological literature, we find indications of renewed activity among the divines of our country. Prof. J. ADDISON ALEXANDER, of Princeton, has a new critical and exegetical work in the course of preparation. Rev. Dr. SPRING will soon publish, through M.W. Dodd, a volume under the title of _First Things_, a series of lectures designed to set forth and illustrate some of the facts and moral duties earliest revealed to mankind. From Rev. Dr. CONDIT, of Newark, we are to have a work entitled _The Christian Home_, setting forth the relations, duties, and benefits of the domestic institution. Rev. H.A. ROWLAND, author of a work on the Common Maxims of Infidelity, has in press a volume under the title of _The Path of Life_. The late EDMOND CHARLES GENET, Embassador from the Republic of France to this country at the close of the last century, left behind him, at his decease, a vast amount of papers, consisting of journals of his life, letters from the prominent statesmen and politicians of this country, and correspondence with his sister, the celebrated Madame Campan. It is understood that members of his family are arranging them with a view to publication. From the close social and political relations which M. Genet, after his dismissal from the embassy, bore to the prominent politicians of the Democratic party, there can be no doubt that these papers, if judiciously edited, will throw much light upon the political history of the period preceding the war of 1812. It is known by those familiar with current Continental literature, that the wife of Prof. EDWARD ROBINSON published, some time since, in Germany, under her usual pseudonym, TALVI, a very full and excellent history of the early Colonization of New England. This work has lately been translated from German into English by William Hazlitt, and published in London. It was published originally at Leipsic in 1847. We presume it will be reprinted here. Rev. H.T. CHEEVER's _Whale and his Captors_ has been reprinted in London, with a preface by Dr. SCORESBY, who commends it very highly. EUROPEAN.
