    NEW GLOBES. W. and S. Jones think it proper hereby to inform the reader, fhat there were recently completed two entire new sets of engraved plates, for Globes of eighteen and twelve inches in diameter. The many recent geographical and astronomical discoveries have ren- dered the old globes inaccurate and obsolete, and new plates in¬ dispensably necessary. On the eighteen inch Terrestrial, are inserted all the latest discoveries from the voyages of Capt. Cook, Vancouvre, Perouse, &c. engraved from an accurate drawing by Mr. Arroivsmith, and all the names of the places delineated in a clear and distinct manner. On the Celestial, are depicted the exact places of more than 6000 stars, clusters, planetary nebulae, &c. communicated by Dr. Herschel, and other astronomers, and calculated in posh tion for the present century, or the beginning of 1800, by W. Jones. The size of these Globes, which is considered of the dimensions the most manageable, renders them comprehensive of many particulars, not to be contained in smaller ones. The gra¬ duations of the great circles are to 20 minutes of a degree; and by simple and improved hour circles, the time is shewn to a few minutes. The Globes are so constructed, as in the simplest manner to be capable of all solutions that it is possible for globes to give, .and in the English language. The general prices per pair are from eight to eighteen guineas, as may be seen with figures in W. and S. Jones’s Catalogue of In¬ struments annexed to this pamphlet. The twelve-inch Globes are reduced copies of the above eighteen, inches, and contain rather more than half the countries, stars, &c. than are upon the eighteen inches. The graduations of the great circles are to SO minutes, or half a degree. The price in plain frames, the pair, is four guineas, and six •shillings for the addition of a compass fitted to both horizons of the Globes. In mahogany claw-feet frames, and, with the com¬ passes fixed under the claw-feet, six guineas the pair. In high frames six guineas and an half the pair. The Globes may be packed securely in packing cases, so as to be safe in conveyance to all parts of the world. FINIS. G. Woodfall, Printer, Angel-court, Skinner-street, London.
