MODERN Fig. 1.—Tissandiers electrical balloon. AERIAL NAVIGrATION. Within the last decade a balloon has been driven against amoderate wind, and a man is said to have flown a hundred yards near Paris. A number ofskilled observers are investigatinj; the elements of air resistances and reactions, and the lawwhich governs flight. The problems of aerial navigation are passing into the hands of theengineers. I. Halloons.—As regards balloons, it has been proved that an elongated gas-bag can bepropelled through the air with a screw, and steered with a rudder; that it can be made stiffenough by internal gas pressure to resist the speeds hitherto attaiTied, and that the velocity islimited by the power and weight of the motor, which the buoyancy of the balloon enables itto carry up. Thus far, as the outcome of various experiments, d
