The waxing ▷ moon-the waning moon. Extraordinary high Spring Tides will happen about the 24th of February, owing to the combined attractive influence of the sun and moon near the equitorial parts of our globe; and which, if attended with strong northerly winds, will be productive of considerable mischief and inconvenience upon our shores next the German Ocean, in the Channel, and in the River Thames, or by south westerly winds in the Irish ea and on our western shores. Rotherhithe. J. LEWTHWAITE. METEOROLOGY. The advantages of meteorological observations can only be available to science by comparing accurate registers taken in different places; we have, therefore, been induced to prevail upon Mr. Watson Perks, of Hitchim, Herts, a gentleman of acknowledged scientific acquirements, to favour us with a copy of his meteorological journal; and have no doubt but that, in connection with the observations upou the atmosphere by Mr. Adams, of Edmonton, with which we have been so long favoured, our readers will find our Meteorological Register, in future, much improved, and therefore more acceptable. 112 LITERARY AND SCIENTIFIC NOTICES. IMPROVED ORGAN.-M. Micg, the Keeper of the Royal Collection of Natural Philosophy, at Madrid, and, who is a great Amateur of Music, has, it is said, from the result of many experiments been enabled to communicate to the organ, a quality which has hitherto been wanting to its perfection, namely the faculty of gradually augmenting or diminishing the strength of its tones. Mr. Cooke has published No. VI. of the Gems of Art, which completes the first Volume of the Work, among its contents will be found Engravings of the celebrated Painting of Correggio: "Christ in the Garden," in the possession of the Dake of Wellington. "Jael and Sisera," after Northcote, in the Council Room of the Royal Academy; "A Gale after Vandevelde," in the possession of G. Morant, Esq.; "The Milk Girl, after Gainsborough," in the Collection of George Phillips, Esq.; "Canal Scene, by Moonlight," after Vanderneer, &c. &c. all of which are executed with the same spirit, taste, and skill, as in the earlier parts, reflecting the greatest credit on the Publisher and the Artists employed. HANOVERIAN AND SAXON SCENERY. -The first part of this new Work of Captain Battye, is published; and if possible, is superior to the same Gentleman's beautiful Illustrations of the Scenery of the Rhine, just completed. This Work is enriched, by the addition of wood cut viguettes to every description; and these being actual views, double the number of subjects in the Volume, making them one hundred and twenty, instead of sixty, as in the preceding Publication. The views chosen are striking and picturesque in the extreme; and among them will be found, The Lochmuhle, Ferdinandstein, Holmstein, and Konigstein, all of which belong to the superior class of landscape, while the Roman Catholic Church at Dresden, is a subject of great interest as an architectural display. The Work is dedicated by permission, to his Majesty; and is truly worthy of the patronage of Royalty. Messrs. Treuttel and Wurtz, the foreign Booksellers, have nearly ready for Publication, in 1 Vol. 8vo. Embellished with a Portrait, a work entitled, Alexander I. Emperor of Russia; or, a Sketch of his Life and of the most important Events of his Reign. A Quarto Volume is preparing for publication, "British Ichthyology," with fine Engravings of the principal Fish of Great Britain, &c. from Drawings taken from Nature, by Sir J. F. Leicester, and some of the first Artists; with a Preface and occasional Remarks, by William Jordan. AFRICAN TRAVELLERS.-At a Meeting of the French Academy of Sciences, on the 19th ult. the Death of the intrepid African Traveller, M. de Beaufort, was announced by M. Jomard. He stated, that, resolved to penetrate farther than had yet been achieved M. de B. had followed the course of the High Senegal, and was directing his route towards Timbuctoo when he fell, another victim to this fatal climate. Mr. Joseph Skelton, Author of the Antiquities of Oxford, is preparing for Publication, upwards of fifty Etchings of Antiquities in Bristol, from original Sketches, taken by the late Hugh O'Neill, illustrative of Memoirs of that City, by the Rev. Samuel Seyer, A.M., or to form a separate volume. FRENCH VOYAGE OF DISCOVERY.— The Astrolabe, French Corvette, commanded by Dumont de Durville, is about to sail on a Voyage of Discovery. The object of the Voyage is to explore certain parts of the Globe imperfectly known, and especially the coasts of New Guinea and New Zealand. A Picturesque Tour in Spain and Portugal, and along the Coast of Africa, from Tangiers to Tetuan, by J. Taylor Knight, and one of the Authors of the "Voyage Pittoresque dans l'Ancienne France," is in the Press. It is to be comprised in twenty-two parts, each containing five engravings, with accompanying letter-press descriptions. LONDON: SHACKELL, ARROWSMITH, AND HODGES, JOHNSON'S-COURT, FLEEP-STREET. THE London JOURNAL OF ARTS AND SCIENCES. No. LXV. Recent Patents. To THOMAS WOOLRICH STANSFELD, of Leeds, in the County of York, Merchant, for his Invention of certain Improvements in Power Looms, and in the Preparation of Warps for the same. [Sealed 27th July, 1824.] THESE improvements, consist, first, in certain contrivances adapted to a power loom, by which the warp threads are given out from the beam, and the cloth taken up by the work roll in a more advantageous manner than has heretofore been effected; secondly, in a mode of putting a series of looms into operation by one rotatory shaft, and of stopping the action of any one of these looms, without interrupting the others connected thereto; and, thirdly, in a method of, and apparatus for preparing VOL. XI. 1 warps, that is, dyeing, dressing, and sizing them at one operation. These contrivances will be best understood by reference to the figures exhibited in Plate VI. Fig. 1, is a section taken across the loom, but in this view several parts which are not new, (such as the apparatus for moving the harness) are omitted in order to shew the improved parts more clearly; a is the roller or beam, upon which the yarn or threads for the warp are wound. The threads pass from the warp beam over a tension rod, b, which extends along the back part of the loom, and under another tension rod, c, affixed to the hinder end of a long lever, d, d. From the rod, c, the warp threads proceed upwards to a roller, e, and thence over another roller, f, through the helds or heddles, h, and through the reed, i, in the lay, k, where the intervention of the threads produce the cloth, and which when woven, is conducted over the breast-beam, l, down to another tension rod, m, affixed at the front end of the long lever, d, and then upwards to the work-roll, o. In order to put the loom in action, rotatory motion is given to the shaft, p, by which means the arms, q, q, are made to revolve; and tappets or friction rollers near the extremities of these arms, acting within the heart-formed frame or lever, r, r, r, cause that frame or lever to vibrate upon its pivot, fixed below in the curved bar, s, s. At the upper end of this frame or lever, r, a rod, t, is attached, which connects the frame, r, with the lay, k, consequently as the frame, r, vibrates, the lay vibrates also, moving with variable velocities in the several parts of its vibration, according to the degree of excentricity of the heart-frame to the rotatory shaft, p. The general construction of the loom having been described, we proceed to explain its actions, which are simi |
