In 1799, Boulton and Watt constructed a heating apparatus, in Lee's factory, Manchester, in which the steinto disuse, and lanterns were substituted.

rent countries, some of which have frequently given results varying widely from the true amount which might be safely carried. In deep, full-built ships the actual capacity was always largely in excess of the government-registered tonnage. More recent laws have, in a great degree, remedied this error, but it is extremely difficult, if not impossible, to contrive any general rule by which perfect exactness can be attained. The rule established by law in the United States, under the Act of 1799, and which continued in force until superseded by that given in the law of May 6, 1864, provided that from the extreme length of the vessel there should be deducted three fifths of the breadth; the remainder was multiplied by the breadth, and the product by the depth, which, in the case of a double-decked vessel, was arbitrarily assumed as being equal to one half the breadth; the latter product was then divided by 95, and the quotient was taken as the legal tonnage on which tonnage dues were

At the beginning of the century it was called a dandy horse ; this was operated by the thrust of the feet on the ground. That of the Baron de Drais, invented at Mannheim, 1817, had but two wheels, and was moved by the thrust of the feet on the ground. Subsequently those driven by a crank movement connected with the wheels and operated by the hands through the medium of cranks or wheels were introduced. Steam-monocycle. The bicycle, patented in En

319). The celebrated wooden bridge over the Rhine, at Schaffhausen, erected in 1757, had a span of 364 feet. A stone pier, the relic of a former structure, existed near the middle of the stream, but it is said that the builder. Ulric Grubenmann, though erecting the bridge directly over this pier, in deference to the timidity of the authorities, apparently using it for a, central support, purposely took care that the bridge should not rest upon it. The bridge was destroyed by the French in 1799. Both Ulric Grubenmann and his brother John displayed great skid and boldness in their bridge constructions. John built a timber-bridge at Kirchenaw, 240 feet in length; and the two, conjointly, one near Baden, 200 feet in length, and another, at Wattenghen, 198 feet long. Wooden bridges. The two leading forms of modern wooden bridges are the lattice, in which the principle of the truss is employed; and the arched, which derives its strength from the actual compression of the wood, t
