SALMONIA, AND CONSOLATION IN TRAVEL. ⛬ This new and uniform edition of the Writings of Sir Humphry Davy embraces the _whole of his Works_, during the space of thirty years (1799 to 1829), a period memorable in the History of Chemistry, and made so, in no small degree, by his own Discoveries. ⛬ _In order to secure to science the full advantage of Discoveries in Natural History, the Lords Commissioners of Her Majesty’s Treasury have been pleased to make a liberal grant of money towards defraying part of the expenses of the following important publications. They have, in consequence, been undertaken on a scale worthy of the high patronage thus received, and are offered to the public at a much lower price than would otherwise have been possible._ 1. By the Authority of the Lords Commissioners of the Admiralty. Now Publishing in Royal Quarto Parts, Price 10s. each, with beautifully Coloured Plates. THE ZOOLOGY OF THE VOYAGE OF H.M.S. SULPHUR, Under the Command of CAPTAIN SIR EDWARD BELCHER, R.N., C.B., F.R.G.S., &c. Edited and Superintended by RICHARD BRINSLEY HINDS, Esq., Surgeon, R.N., attached to the Expedition. The extensive and protracted Voyage of Her Majesty’s Ship “Sulphur,” having been productive of many new and valuable additions to Natural History, a number of which are of considerable scientific interest, it has been determined to publish them in a collected form, with illustrations of such as are hitherto new or unfigured. The collection has been assembled from a variety of countries, embraced within the limits of a voyage prosecuted along the shores of North and South America, among the Islands of the Pacific and Indian Oceans, and in the circumnavigation of the globe. In many of these, no doubt, the industry and research of previous navigators may have left no very prominent objects unobserved, yet in others there will for some time remain abundant scope for the Naturalist. Among the countries visited by the “Sulphur,” and which in the present state of science are invested with more particular interest, may be mentioned the Californias, Columbia River, the Northwest coast of America, the Feejee Group (a portion of the Friendly Islands,) New Zealand, New Ireland, New Guinea, China, and Madagascar. Animated by a devotion to science, the following gentlemen have liberally engaged to undertake those departments with which each respectively is best acquainted. The Mammalia will thus be described by Mr. J. E. GRAY; Birds, by Mr. GOULD; Fish, by Dr. RICHARDSON; Crustacea, by Mr. BELL; Shells, by Mr. HINDS; Radiata, by Mr. J. E. GRAY. PLAN OF PUBLICATION. I. The work will extend to about _Twelve Parts_, one of which will appear on the 1st of every third month. II. The Parts will be published at the uniform price of _Ten Shillings_, and it is intended that each department shall, as far as possible, be complete in itself.
