COLONEL SIBTHORR's MOTION FOR A REDUCTION ON THE DUTY OF FIRE INSURANCE.—As most of our readers are men of property, we beg to draw their most serious at- tention to the propriety, nay, their imperative duty of sup- porting the gallant Colonel's motion, by calling public meetings and sending petitions to the legislature without any delay. Three shillings per cent. per annum duty, at these acknowledged distressed times, is really too high, and were it reduced one half, as it should, even the revenue, as well as the public at large, would be greatly benefitted. We call on every patriot to lend his signature to so desirable and substantial a reform. MR. VIGERS'S PATENT PROCESS FOR PURIFYING AIR A very interesting experiment was lately made at No. 3,. Alderman's-walk, Bishopsgate, illustrative of this valuable process, in the presence of several gentlemen largely interested in mines, and others of great scientific attainments, which was conducted by Messrs. Blyth, engineers, of Limehouse. The apparatus consisted of a purifying machine, in an air- tight box, communicating, by means of a small tube, with a vessel containing oxygen gas. The tube was provided with a stop-cock, in order to .admit or exclude the oxygen. A lighted candle was placed in the box, which was hermetically sealed, and the supply of oxygen cut off. The candle thus burned for three minutes and a half, and then went out. The box being opened, and the candle re-lighted, the same experiment was continued until the candle was on the point of expiring, when the machine being put into operation, and a small quantity of oxygen admitted, the candle at once re- sumed its original appearance, giving out a healthy flame, which continued for some time, and the experiment was re- peated until every gentleman present expressed himself unequivocally satisfied with the utility and importance of the invention. Some oxygen gas was generated in the room, to show the facility with which it might be done—indeed, it appeared easy to generate this gas in a table spoon over a candle. The principle thus established is an elucidation of a well-known fact, that where the air is sufficiently pure to support combustion, it is also capable of supporting life, and the experiment shows that persons can breathe freely, by means of this apparatus, in the levels of mines, without the customary air-shafts, where, otherwise, the work must be discontinued for want of air. CORNISH STEAM ENGINES.—By far the largest engine ever constructed is now in progress of manufacture at Hayle. The piston rod, which was forged last week, is 19 feet long, 13 inches diameter in the middle and 16 inches in the cone, and weighs three tons 16 It will work in an 18-inch cylinder, which will stand in the middle of another cylinder of 144 inches diameter. Five other piston rods will work between the inner and the outer cylinders. The 80-inch cylinder was cast last week, and the large one will be cast soon. The pumps are to be 64 inches in diameter! a mea- surement which may afford some idea of the size and power of the engine. It is intended for draining Haarlem Lake, in Holland.—Falmouth Packet. DEOREASE IN THE PRICE OF BRITISH IRON.—Since the commencement of 1842, a continued gradual depression in the price of English iron has taken place. In January, in that year, bar iron was -quoted at 140s.; cargo in Wales, 120s.; hoops, 200s.; sheets, 220s.; pig in Wales, 82s. 6d.; pig in Clyde, 60s. Slight advances and increasing depres- sion have marked the intervening period to the end of March, when the following prices only were obtained, being a falling off of about 23 per cent. in fifteen mouths:—bar, 105s.; cargo in Wales, 155s.; hoops, 155s.; sheets, 170s.; pig in Wales, 70s.; pig in Clyde, 4Ss. IMPORTANT MINING CASE—GREAT WHEAL PROSPER.— An action (Clouter v. Francis and Trevethan) has just been tried in the Stannaries' Court, to recover the sum of £3289 18s. 7d., with interest" of the defendants, as share- holders in the Great heal Prosper Mine, being the amount advanced by the Western District Banking Company, for carrying on the mine. In the course of evidence, elicited in a long cross-examination, it appeared that the account had been kept open entirely by acceptances—originally, two of £500, one of JE430, and one of £ 428—which were succes- si\ely renewed, and as often dishonoured, from February, 1837, to December, 1838. The action had been brought in the Vice-Warden's Court, where the plaintiff failed to get a decision in his favour. Witnesses were examined, to prove the advances of the money by the bank, and the defendants* connexion with the concern as shareholders, when the jury found a verdict tor the plaintiff, £ 1500. TELEGRAPHIC COMMUNICATION.—Mention is made in accounts from Germany of the discovery of a new telegraphic means of communication, adopted on the Upper Silesian Railway, with very successful results; its application seems to be most valuable at night, and its celerity is four times greater than that of the ordinary telegraphs. The expense, on the other hand, is represented as very trifling, it having- been estimated that the several trials made upon the occasion in question did not cost more than two silver groschene, or about three-pence. Every improvement of this kind is im- portant, as increasing the safety of railway travelling.
