certainty and accuracy than had hitherto been obtained. In his statement on Monday evening, he described the various adjustments which he found it necessary carefully to make in order to insure the requisite degree of accuracy in the observations; and the difficulty and embarrassment which occurred in consequence of considerable errors which exist both in the signs and in the numerical values of Laplace's theory of the satellites of Jupiter. Finally, all these difficulties were overcome; and the result is, that the mass of Jupiter is most probably 1-1050th of the Sun, 1-1054th (Nicolai's determination) being much less probable, and 1-1070th (Laplace's) very improbable.

A meeting of the Philosophical Society was held on Monday evening, the Rev. Professor Sedgwick, the president, being in the chair. A memoir by the Marchese Spineto was read, containing objections, founded on astronomical considerations, and on the examination of ancient authors, to the chronological system of Sir Isaac Newton; and reasons for preferring the more extended chronology which is suggested by the study of Egyptian antiquities. After the meeting, Dr. Jermyn exhibited various ornaments of glass and enamel, a bronze bracelet, and other implements of metal, and vessels of earthenware, some of them of the kind called "Samian." These relics were found in association with bones, partly interred and partly deposited in urns, which have been discovered at Exning and at Bartlow, in this neighbour hood. The skeletons have invariably been found lying in threes, with their faces downwards. Professor Sedgwick

also gave an account, illustrated by drawings and sections, of the geology of North Wales. He stated that, by vari ous traverses across Caernarvonshire and Merionethshire, it was ascertained that the strata of that district are bent into saddles and troughs, of which the antichnal and synclinal lines occur alternately, and are all nearly parallel to the "great Merionethshire anticlinal line." The direction of these lines is nearly N.E. by N., and S. W. by S.; and they appear to pass through the following points-(1) Near Caernarvon, (2) Myndd Mawr, (3) Garn Drws y Coed, (4) Moel Hebog, (5) Moel Ddu, (6) Between Pont-Aberglas-lyn and Cnicht, (7) The great Merioneth anticlinal, (8) The West side of the Berwyns, (9) The calcareous beds to the West of Llanarmon Fach. The bearing of these facts upon the general views of Elie de Beaumont was noticed; and it was observed that the approximate parallelism of the most prominent mountain chains of Wales, the Isle of Man, Cumberland, and the South of Scotland, corroborate the justice of this theory up scale these apparently parallel straight to a certain point; although on a wider lines may be found to be portions of curves

of small curvature.

The Royal Dublin Society proposes, with the concurrence and assistance of the Manufacturers, Artists, and Artisans of this country, to institute an Annual Exhibition of Irish Manufactures, Productions, and Inventions, conformable to the plan which, for several years, has been followed with signal advantage in Paris, and other capital cities on the continent; -and also in London and Edinburgh.

By the opportunity which will be thus afforded of seeing the variety and excellence of articles really manufactured in Ireland, and of which many persons at VOL. 1.

present are little aware, the public will, doubtless, be gratified, and will be induced to patronize their improvement; and the spirit of emulation which can scarcely fail of being excited among the Exhibitors, must tend to national advantage.Honorary distinctions, in the form of medals or certificates, are to be conferred for any extraordinary excellence, whether in workmanship or invention.

Several distinguished manufacturers in the city of Dublin, and its vicinity, have already signified their approbation of the plan, and their intention to assist and

May 2.

Mr. Hawthorne presented the following report from the Selected Committee, in conjunction with the Committee of Chemistry and Mineralogy

It having appeared to these Committees since their last report, that the allowance of £150 to the late Sir Charles Giesecke, as Keeper of the Museum, was only personal to him, and not intended to apply to his successor; they are of opinion, that it will not be in the power of the Society to offer to such persons as may be Candidates for the vacant situations, more than the salary enjoyed by Sir Charles Giesecke, of £150, as Professor of Mineralogy; and they recommend to the Society, that they should endeavour to procure for the latter annual salary, (with the liberty of keeping private classes,) a person qualified by his knowledge of Mineralogy, Geology, and Natural History, to take charge of the Cabinet of Minerals, and of the Museum; and that these Committees should have the same authority as that delegated to them on the 4th April last, to invite scientific men to propose for the Professorship.

"CHARLES S. HAWTHORNE "Chairman."
