The papers read during the year just passed are fewer than in some of the preceding years, but they are equally important, and some of them of a peculiar practical nature; and the discussions at some of the meetings have been highly interesting and instructive. In November last a paper was read, by Mr. Joseph Bewick, on the Ironstone Deposits of Rosedale, a paper, which, combined with that of Mr. John Marley, on the Cleveland Ironstone generally, has aided in elucidating the great ironstone formation of Cleveland, which has so powerfully attracted the attention both of the scientific and commercial world. And the special discussion which took place at the July meeting, especially on the Rosedale ironstone, has tended to throw additional light upon that peculiar and important deposit. A valuable paper was also read by Mr. Henry J. Plews, of Bedale, on the Coal-field of New South Wales, accompanied by elaborate maps and figures of the several fossil remains found in that important coalfield. Specimens of several of the fossils of this formation, nearly agreeing with those of the British coal measures, were exhibited by Mr. Plews, and presented to the Society. (viii) The Institute has also this year been favored by Mr. T. Y. Hall with extensive statistical calculations and statements of the Production and Consumption of Coal in France, with map. At the May meeting a short but instructive paper was read by M. Laurent, and a model exhibited, illustrative of a plan of machinery for Ventilating Mines, invented by M. Lemielle, and now in operation in some of the coal mines in France. And, at the June meeting, Mr. J. J. Atkinson, Inspector of Coal Mines, favored the meeting with some elaborative calculations and investigations on the efficacy and economy of such machine, as compared with the furnace and some other modes of ventilating coal mines. The discussion on the Lundhill Accident, and on the Ventilation of Coal Mines generally, has occupied the meetings of the Institute, a subject peculiarly applicable to the Society. And, at the May meeting, and subsequently, papers were read by Mr. Atkinson, illustrative of the Distribution of Air in Coal Mines, and, more especially, on the subject of Splitting Air, and the advantages derived therefrom, and, likewise, on the laws which govern currents of air passing through, and distributed throughout mines in different states of atmospheric influences. At the August meeting, a paper on the Ventilation of Mines, as connected with the system in use at Lundhill colliery at the time of the accident, and on the system of working and ventilating the coal mines of that district, illustrated by drawings, was read by Mr. John Wales, who also exhibited diagrams of the different modes of ventilation, and which led to a most important practical discussion of the ventilation of the coal mines above alluded to, and of coal mines generally. These papers, and such of the discussions as could be embodied in the proceedings of the Institute, will constitute important additions to the earlier volumes of the "Transactions" of the Society. The Council are glad, also, to report an increase of members, the number added during 1857-8 having been twenty-eight. The Society has, however, to lament the loss of three members by death, viz., Mr. Ralph Dixon, of Durham, Mr. E. Southern, of Kibblesworth, and (ix) Mr. George Heckles, of Shincliffe. The Council have, also, to lament the loss of one of the honorary members of the Society, Mr. Herbert Mackworth, Inspector of Coal Mines, who died on the 13th July, at the premature age of thirty-four. Thus, therefore, the nett increase of ordinary members in 1857-8 is twenty-five. On the question of finance, the Council, as usual, refer to the Report of the Treasurer and Finance
