Submarine Illumination by the Drummond Light. We find by the Irish newspapers, that Mr. Steele, who has devoted himselt with so much ardour to the subject of submarine operations, and who is the inventor of the communicating divingbell, has lately made a very important improve ment in this departinent of physica' science. This improvement consists in the substitution for the light which he originally proposed for the irradia. tion of objects under water, of what he calls "the piercing ray of the Drummond light in its gorgeous glory." He has con nited several highly distinguished engineers of this m trop lis, and they have been unanimous in their opinion, that this new ap plication of the Drummond light is an improvement of the greatest importance, an it is impossible that any thing can be more simple than the mode pro-" posed by Mr. Steele for its application to his pur pose. It appears from the Irish newspapers that this improvement in his theory was made by him while observing Mr. Deane's operations at Kilkee, on the coast of the county Clare. We have seen several of Mr. Steele's publications on this subject in the journals of our Irish contemporaries, and he writes in terms of measureless admiration of the. infinite beauty and perfection of Mr. Deane's sys tem of rapid diving. Among the London engineers who have expressed the highest approbation of Mr. Steele's new theory of submarine irra. diation by the Drummond light, is, we understand, Mr. Alexander Gordon, who has particularly applied himself to the subject, and lately obtained a patent for a very beautiful mode of generating and applying the oxy-hydrogen gas.-Sun. Manumotive Carriage.-A mechanic, a whitesmith by trade, named Nicholson, of the town of Enniscorthy, has invented a new carriage, on cost simple principles. It is very ingeniously constructed, having three wheels, one in front and Two behind-the latter about three feet in diameter, the former one and a half. It is propelled by an iron baudle, which the guide moves to and fro with the right hand, and not tiresome, being quite a gentle motion; on the left there is a small lever, to he touched by the finger when any obstruction appears on the road, which raises the first wheel over such impediments, and prevents the guide from receiv ing any shock or interruption. Then over the sma wheel there is a handle, or tiller-stick, to be touched when the driver wishes to turn the gig, and which is done instantan ously; there is another spring for the foot. whi h retards the progress of the machine. The maker is quite confident of its ultimate success, and says he can improve on the general principle, the present mo, del being too small to contain more than one per sou; and we suppose the driver or guide would work it for eight or ten miles without tiring. It has taken the artist some years in its completion, and we wish him every success and encouragement to which his genius and industry justly entitle him.-Dublin Paper. Another Locomotive-Engine for Russia. - Oa Thurs tay, the 15th of September, a large and power. ful locomotive-engine, built by Mr. Timothy Hackworth, of New Shildon, for the Emperor of Russia, was shipped on board the Barbara, at Middlesbro'. This engine is constructed on an improved prin ciple, and finished in the best manner. She has been tried on the premises, and propelled at the rate of 72 miles per hour. It is said that this ma chine, and the similar one built at Newcastle, will, on their arrival at St. Petersburgh, have cost A the Emperor upwards of 2,000, each. Who, a few years ago, would have dreamed of the exportation of machinery from the river Tees. This engine is for travelling on the railroad from St. Pet rsburgi to Pawlowsky, where stands one of the country palaces of his Imperial Majesty.-From a Correspondent. Magnetic Balance.-Could not small philosophical scales be more nicely suspended by magnetism than by the present method; with the precaution, to use no metal in their construction acted on by magnetism, except the centres, the edges of which must be reversed?-TYRO-MECHANICUS. Correction.-Sir, If you will review p. 383, you will find that some alteration of the manuscript text of that paper on "The Tides"-through inad vertent omission, I apprehend-has rendered the pa sage unintelligible as it there stands. I there. fore beg leave to send you the subjoined emenda. tion, in failure of the original being at hand "It is manifest that atmosphere, a transparent firmament, is interposed to contret (not originate,. if to qualify the hues by extraneous floating particles of moisture,) the light, however distant; rather than, by a property at variance with its fitness as medium of all rays, to impede their progress to recipient vision."-W.
