ONE RAIL RAILROAD. SHOW WORKING MODEL English Inventor Overcomes Gravitation With the
 Gyroscope.

The announcement of another great triumph of science, of perhaps epoch making importance, was made this evening before, brilliant assembly gathered under the auspices of the Royal society. For more than two hours the leaders of the English sci entific world listened to the exposition of well known principle of mechan- ics for the first time practically ap- piled and watched a marvellous dem- onstration which seemed to set the laws of gravitation at defiance. At the close they claimed it's discoverer or inventor as worthy to rank high upon the roll of honor which bears the names of Newton and Watts and Ste- phenson.
 What they saw was this: A ninia- ture railway car or locomotive stand ing entirely above a single rail with apparently nothing to balance it ran about the hall, turned sharp corners at high speed, crossed a single strand of wire cable in lieu of bridge and climbed heavy incljnes-all with per feet stability. It was sometimes foad- ed, sometimes empty There was no attempt to balance the load; the vehicle itself did that instantly and automatically. Every attempt to un- balance 1t resulted in paradox If the load were piled all upon one side it seemed inevitable that the vehicle would sag, if indeed 1t did not topple over. But no, the overloaded side automatically rose in proportion to the burden and the empty side was de- pressed. To the uninitiated the thing was uncanny, an Alice in Wonderland reality.
 The inventor, Louis Brennan, who is also the inventor of the torpedo bearing his name, describes his new system as follows:
 The characteristic feature of this sys- tenn of transport is that each vehicle is capable of maintaining it's balance upon an ordinary rail laid upon sleep- CTS on the ground, whether it is stand ing still or moving in either direction at any rate of speed, notwithstanding < that the center of gravity is several fleet above the rail and that wind pres sure, shifting of load, centrifugal action or any combination of these forces may tend to upset 1t.
 Z Automatic stability, mechanism of fextreme simplicity carried by the ve- { hicle itself endows it with this power The mechanism consists essentially oi two flyWheels rotated directly by cleo tric motors in opposite directions at a very high velocity and mounted so that their gyrostatic action and stored-uT energy can be utilized. These fywheels are mounted on high class bearings anc are placed in exhausted cases, so thai both air and journal friction is reduced to minimum, and consequently the power required to keep them in rapid motion is very small.
 The stored-up energy in the fly wheels, when revolving at full speed is so great and the friction so smal that if the driving current is cut of altogether they will run at sufflcien velocity to impart stability to the we. hicle for several hours, while it vii take from two to three days before they come to rest. The stability me. chanism occupies but little space ana is conveniently placed in the cab a one end of the vehicle. Its weight i! also small, about per cent. of thu total load being considered an ampl, allowance for the first vehicle.
 The road wheels are placed in a sin gle row beneath the center of tn, vehicles, instead of in two rows nea, the sides. as usual, and are carried oi bogies or compound bogies which ar, not only pivoted to provide for hori zontal curves on the track, but fo vertical ones also By this means tn vehicles can run under curves of evel less radius than the length of tn vehicle itself, or on crooked rails o rails laid over uneven ground withou danger of derailment.
 The motive power may be eithe petrol, oil, gas or electricity, as con sidered most suitable for local con ditions. In the first instance, howeve it has been decided to use petrc electric generating set, carried by tn vehicle itself, for the supply of cur rent to the road wheel motors an to the stability mechanism. Such
 vehicle will have the great advantage c being always ready for immediate us' the gyro wheels being kept constantl running by a current from small ao oumulator while the engine is at tn rest. In order that the vehicle may b able to ascend steep inclines tn wheels are all power droven change gears are provided for use in hill country. It is also possible to run fire wheel down hill at great velocity, s that a good average rate of speed ca be attained.-London Dispatch to Ney York Sun.
