magnificent chateau? The storm-cloud below makes the outlines of objects
waver; and it requires a practised eye to recognise localities."

"You are certain that it is Darmstadt?"

"Undoubtedly; we are six leagues from Frankfort."

"Then we must descend."

"Descend! you would not alight upon the steeples!" said the unknown,
mockingly.

"No; but in the environs of the city."

"Well, it is too warm; let us remount a little."

As he spoke thus, he seized some bags of ballast. I precipitated myself
upon him; but, with one hand, he overthrew me, and the lightened balloon
rose to a height of 1500 metres.

"Sit down," said he, "and do not forget that Brioschi, Biot, and
Gay-Lussac, ascended to a height of seven thousand metres, in order to
establish some new scientific laws."

"We must descend;" resumed I, with an attempt at gentleness. "The storm
is gathering beneath our feet and around us; it would not be prudent."

"We will ascend above it, and shall have nothing to fear from it. What
more beautiful than to reign in heaven, and look down upon the clouds
which hover upon the earth! Is it not an honour to navigate these aerial
waves? The greatest personages have travelled like ourselves. The
Marquise and Comtesse de Montalembert, the Comtesse de Potteries, Mlle.
La Garde, the Marquis of Montalembert, set out from the Faubourg St.

address and presence of mind in his ascension of the 15th of July, 1784;
at Lyons, the Comtes de Laurencin and de Dampierre; at Nantes, M. de

Andreani; in our days, the Duke of Brunswick; have left in the air the
track of their glory. In order to equal these great personages, we must
ascend into the celestial regions higher than they. To approach the
infinite is to comprehend it."

The rarefaction of the air considerably dilated the hydrogen, and I saw
the lower part of the aerostat, designedly left empty, become by degrees
inflated, rendering the opening of the valve indispensable; but my
fearful companion seemed determined not to allow me to direct our
movements. I resolved to pull secretly the cord attached to the valve,
while he was talking with animation. I feared to guess with whom I had
to do; it would have been too horrible! It was about three-quarters of
an hour since we had left Frankfort, and from the south thick clouds
were arising and thr
