651. BALLOONS, Experiments with.—
There seems a possibility that the great desideratum
in the use of the balloon may be obtained.
There are two persons at Javel ( opposite
to Auteuil), who are pushing this matter.
They are able to rise and fall at will, without
expending their gas, and they can deflect forty-five
degrees from the course of the wind.—
To R. Izard. Washington ed. i, 443.
