The grsndest Suspension Bridge in the world, we suppose, is one recently completed at the city of Pesth. In the dominions of Austria. This bridge was commenced in lS40. according to the design and under the direction of William Tierney Clark an English civil engineer. It extends over the DannheS and has clear water way of l,2j0 feet, the centre span being 670 feet. The height of the suspension towers from the foundation is 200 feet but they have 90 feet of foundation in the water,
 The sectional area of the s,;sp.nJuy cl,nf1s-iS 520 square inches of wrought iron, and the total weight of the same l, 300 tons This is the first permanent bridge since the time of the Romans, which has been erected over the Danube, below Vienna; il having been considered impossible to fix the foundation in so rapid river, subject 10 such extensive floods, and exposed to the enormous force of the ice in the winter season. It now. however, stands as another monument of skill and pcrsever- ance. This bridge open for the first time, not to an ordinary public, but to retreaing army, on the 5th of January, lS49-by which the stability of the structure put to the most severe test.
 A correspondent, writing to the London Times respecting this event, says: First came the Hun garians in full retreat and in the greatest disorder hotly pursued bythe victorious mperallsts; squad rons of artillery and cavalry in full gaop, backed by thousands of niantry--in fact. the whole plat form was one mass of moving soldiers; and during the first two days 900 imperial troops, with 270 pieces of cannon, passed over the bridge.'
 This fact cannot but be of importance to the scientific world, since it proves that suspension bridges, when properly constructed and trnsscd according to the design of that bridge, may be erected in the most exposed places while the cost. in comparison with stone bridges, is comparatively insignificant.
 The above bridge has gigantic span The great Mena bridge, by Telford, is 560 feet between the points O. suspension, and is therefore II0 feet less in span than the new bridge over the Danube The suspension bridge at Fiborg, in Switzerland s splendid york; but Is not equal the bridge al Pesth either
 America boast of some grand bridges; espe- cially has she been famous, perhaps above all na- tons, for wooden bridges. The colossus oyer the Schuylkill was grand structure, and there are some others that we might mention Our architects have been famous for their skill in rearing wooden structures and we believe they were Americans who erected the long bridge of Derry In Ireland.
 lt IS not long since that one of our citizens, Mr Remington, was astonishing the inhabitants of Britain tand is so yet for aught know) with his skill in bridge architecture. We believe that he asserted in of his letters that ' his bridge was well secured by patent at home-America" We have in vain endeavored to discover his patent caim cannot tell in what particular his invention, if any, consists; but this know, that the Flying Pendent Lever Bridge k not new invention If any one will turn to Popes Treatise on Bridge Ar. chtecture, published by Alexander Nvcn, No. I20 Duane street, this city, in lsii he will the de- sign of bridge spanning the noble Hudson from
