New Steam-boat Enterprise. A company has been formed for a steam.boat communication between Vienna anti Smyrna, by the Danube, the Black Sea, and the Straits. Pas,engers whose business calls them into Austria, and who have no occasion ¢o stop at Moldavia or VCalachia, will not be subject to quarantine at Gatatz, and only 5 days at ()rsova. It was necessary, before this route was ,,stablished, to subtnit to g4 days quarantine, i. e.'14 at Galatz, and 10 at OrSova,

JE!astic Boots with Movable Heels. By M. Q~gNET. This invention has been patented, While the patentee preserves the enth'6 elegance of the form of the boot, he has discovered the means of preventing t~e pain arising from the swelling of the fl)ot. By a slight pressure on the bolt of a spring, the whole sl~oe may be |engthened about 12 lines. It is very convenient for those who in walking press harder on one side than the other. The mobility of the heel, and its peculiar structure, cause it to wear equally in all parts. Iaef~.
~Fonvielle's Filterlnff 3pparatus. A trial has been had in the Courts at Paris, relative to the validity of the claims of the "French Filtering Company," who are now the possessors of Fonvielle's patent, to an exclusive right, founded on the merits of this in* vention. It was urged by the opposing party, that this right, being depen,lent on the application of high pressure, is invalidated by the [act of a prior use of the same principle to the process of filtration, as was shown by brevets (patents) of an anterior date. This plea was answered on behalf of the Company, b); the proof tl~at Fonvief[e's n'mde of applying high pressure was entirely different from those of his predecessors. These were to force the water through tissues of felt, wool, or flaX, or through skins, while Fonvielle's consists in filtering through sand, .pounded stones, gravel, and other inert animal substances, which is so diflbrent that previous to this date it had been found impracticable to apply high pressure to such filters, the effect being inevitably to overturn the filtering bed and confound the mate,'isis with the liquid to be filtered;--t~hat this being the difficulty,all ,e~ed ia t~: consisted the merits of the invention.
