Dr. Brewster, having seceded from the Edinburgh Journal of Philosopy, is about to publish a new work upon a similar plan, in quarterly numbers; which is to be entitled The Edinbugh Journal of Arts and Sciences. From the pro, spectus, which has fallen into our hands, containing the names of contributors, and the subjects announced, we have every reason to expect a work of considerable interest; and though there are so many of a similar kind, the name of the editor is enough to warrant the expectation, that this will be no inconsiderable acquisition to science. M. Cuvier, the celebrated naturalist, has lately presented a Memoir, addressed to the Academy of Sciences, at Paris; exhibiting the present state of knowledge in the science of natural history, the details of which are highly interesting. Linnæus, in 1778, reckoned nearly 8,000 species of plants; there are now above 40,000 noticed. Buffon estimated about 300 quadrupeds; they are now increased to above 700, and the catalogue is still considered incomplete. M. de Lacepede, who, twenty years ago, wrote a History of the Known Species of Fish, did not enumerate more than 1,500; and there is now contained in the Cabinet of the King of France alone, above 2,500. M. Cuvier considers this number but a small proportion of what may be yielded by the seas and rivers. The immense number of insects is truly surprising, above 25,000 species are reckoned, and they are continually augmenting, by the collectioms of travellers in hot climates. A microscopic work of M. Strauss, on the Maybug, shews that that animal, not exceeding one inch in length, contains 306 hard pieces as, envelopes; 494 muscles; 24 pair of nerves; and 48 pair of trachea. Mr. Maugham, author of the Pupil's Pharmacopoeia, is printing, uniformly with the Phar. Lond. an Appendix to that work, comprising a concise History of the Materia Medica, and the preparations contained therein; with a brief notice of their doses, virtues, and uses. The lately discovered work of Milton, is about to be printed at the University. Press of Cambride, and will be published together with a translation, under the immediate sanction of His Majesty; the work will be of some magnitude as the M.S. consists of above 700 pages. A Treatise on the Zoology of Mexico, by Mr. Swainson, is in the press, it will contain descriptions of the animals lately collected there by Mr. Bullock, and is intended as an appendix to the travels of that gentleman. Mr. John Edward Gray is preparing for publication, by subscription, a series of the Genera of Mollusca; illustrated with plates of each section, and of all the new species. The work, when completed, will form a history of all the known species of fossil, shell, and molluscous animals. Each part will form a complete work of itself, and may be subscribed for separately, as it will be furnished with indexes, and an arranged list of the strata of the Fossil species, &c. GREEK CHRONICLE.. A newspaper has been established in Greece, printed from the types presented to the Greeks by the late Lord Byron; it is under the superintendance of a German, M. Mayer; and it professes to treat on political news, debates in the senate, foreign correspondence: morals and legislation, and of the advancement of, and discoveries in the arts, sciences, and manufactures, and foreign intelligence connected with Greek literature. The Geographical Society of Paris, which has been instituted only two years, has greatly forwarded this important and beneficial science; the first volume of its proceedings contains some valuable communications from remote parts of Asia, and the interior of Africa, as well as from several parts of the new world. The second volume comprises, the enquiries of travellers who are about commencing journies to distant countries, to obtain such information from the Society, as may render their travels more useful to science. Among those about to set forward are Messrs. Buissou d'Armandy, and Ch. de Sauvigny, both members of the Society; the first to Moca, and the latter to Calcutta. The honorary rewards, offered by the Society, are of considerable value; medals of from 3000 Francs to 500 to be presented on the completion of Journies with a manuscript for the use of the Society for publication. 1 LONDON: SHACKELL AND ARROWSMITH, JOHNSON'S-COURT, FLEET-STREET. THE London JOURNAL OF ARTS AND SCIENCES. No. XLIV. Recent Patents. To SAMUEL BROWN, late of Windmill-street, Lambeth, in the County of Surrey, but now of Printing-house Yard, Blackfriars, in the City of London, Gentleman, for his new invented Engine or Instrument for effecting a Vacuum, and thus producing power by which Water may be raised, and Machinery put in motion. [Sealed 4th December, 1823.] THIS is an hydro-pneumatic engine, partaking of the principles of Savery's and Newcomen's steam-engine, and also of some modifications of the same principles subsequently introduced by others; but instead of condensing steam within the cylinders to effect a vacuum, the exhaustion is here to be produced by ignited gas, issuing from jets, which by consuming the air in the closed vessels, permits the superincumbent atmosphere to force water up tubes into VOL.
