Six shots were poured in with tremendous precision and effect, and the seventh tore away one of the main supports of the bridge, and down went the densely crowded column into the Rhine; at the same instant, the guns of our launches opened a destructive fire upon the banks, which soon were swept clean of the enemy.

High up on the stream, and for nearly a mile below also, we could see the boats of our army pulling in for shore; the crossing of the Rhine had been effected, and we now prepared to follow.

To be continued.

AN AERIAL VOYAGE.

Of all the wonderful discoveries which modern science has given birth to, there is perhaps not one which has been applied to useful purposes on a scale so unexpectedly contracted as that by which we are enabled to penetrate into the immense ocean of air with which our globe is surrounded, and to examine the physical phenomena which are manifested in its upper strata. One would have supposed that the moment the power was conferred upon us to leave the surface of the earth, and rise above the clouds into the superior regions, a thousand eager inquirers would present themselves as agents in researches in a region so completely untrodden, if such a term may here be permitted.

Nevertheless, this great invention of aerial navigation has remained almost barren. If we except the celebrated aerial voyage of Gay-Lussac in 1804, the balloon, with its wonderful powers, has been allowed to degenerate into a mere theatrical exhibition, exciting the vacant and unreflecting wonder of the multitude. Instead of being an instrument of philosophical research, it has become a mere expedient for profit in the hands of charlatans, so much so, that, on the occasion to which we are now about to advert, the persons who engaged in the project incurred failure, and risked their lives, from their aversion to avail themselves of the experience of those who had made aerostation a mere spectacle for profit. They thought that to touch pitch they must be defiled, and preferred danger and the risk of failure to such association.

It is now about two months since M. Barral, a chemist of some distinction at Paris, and M. Bixio, a member of the Legislative Assembly (whose name will be remembered in connection with the bloody insurrection of June, 1848, when, bravely and humanely discharging his duty in attempting to turn his guilty fellow-citizens from their course, he nearly shared the fate of the Archbishop, and was severely wounded), resolved upon making a grand experiment with a view to observe and record the meteorological phenomena of the strata of the atmosphere, at a greater height and with more precision than had hitherto been accomplished. But from the motives which we have explained, the project was kept secret, and it was resolved that the experiment should be made at an hour of the morning, and under circumstances, which would prevent it from degenerating into an exhibition. MM. Arago and Regnault undertook to supply the aerial voyagers with a programme of the proposed performance, and instruments suited to the projected observations. M. Arago prepared the programme, in which was stated clearly what observations were to be made at every stage of the ascentional movement.

It was intended that the balloon should be so managed as to come to rest at certain altitudes, when barometric, thermometric, hygrometric, polariscopic, and other observations, were to be taken and noted; the balloon after each series of observations to make a new ascent.
