EDINBURGH: WILLIAMS & NORGATE, SOUTH FREDERICK STREET. THE NATURAL HISTORY REVIEW: A Quarterly Journal of Biological Science. In undertaking the conduct of the NATURAL HISTORY REVIEW, the Editors propose to establish a QUARTERLY CRITICAL JOURNAL OF BIOLOGICAL SCIENCE, which, without interfering with existing scientific periodicals, shall stand in the same relation to naturalists, and other persons interested in biological inquiries, as that which is occupied by the ordinary Quarterly Reviews in respect to men of letters and the general public. They desire, in addition, to offer to all whom it may concern a means of discussing the general problems suggested by the progress of biological investigation in a scientific spirit, and without reference to any but scientific considerations. The Editors will not refuse an original communication on the ground of any scientific opinion expressed in it. The Contents of the NATURAL HISTORY REVIEW will be of the following nature : I. Reviews and Notices. II. Original Articles. III. Proceedings of Scientific Societies. The first section will embrace criticisms, more or less extended, of new biological works and papers published either in this country or abroad, together with careful Reports upon the present condition of particular branches of Natural History. The second will comprise such original papers as may be of sufficient importance to deserve publication, though they may not be of a nature to demand a place in the Transactions of a Scientific Society. In the third section will be given an account of the Proceedings of the leading Scientific Societies; and the fourth will contain Miscellaneous Notes, and notices of remarkable events in Natural History. As the wide extent of Biological Science renders it impossible for any man to be largely acquainted with more than two or three of its branches, the Editors have divided the labour of collecting and supervising the requisite materials according to the scheme on the preceding page. The Editors do not hold themselves responsible for the opinions expressed in articles to which their names are not attached. Communications intended for the Journal should be addressed to the Publishers, the words "Natural History Review" being written upon the outside cover. THE NATURAL HISTORY REVIEW will be published on the first of January, April, July, and October. Single numbers, price 4s. each, will be on sale in the usual way. Annual Subscriptions, at the reduced rate of 12s., should be sent to the Publishers direct, who will forward the Numbers, post free, on the day of publication. |
