"The machine in which we proposed to embark, was a copper vessel, that would have been an exact cube of six feet, if the corners and edges had not been rounded off. It had an opening large enough to receive our bodies, which was closed by double sliding pannels, with quilted cloth between them. When these were properly adjusted, the machine was perfectly air-tight, and strong enough, by means of iron bars running alternately inside and out, to resist the pressure of the atmosphere, when the machine should be exhausted of its air, as we took the precaution to prove by the aid of an air pump. On the top of the copper chest and on the outside, we had as much of the lunar metal (which I shall henceforth call _lunarium_) as we found by calculation and experiment, would overcome the weight of the machine, as well as its contents, and take us to the moon on the third day. As the air which the machine contained, would not be sufficient for our respiration more than about six hours, and the chief part of the space we were to pass through was a mere void, we provided ourselves with a sufficient supply, by condensing it in a small globular vessel, made partly of iron and partly of lunarium, to take off its weight. On my return, I gave Mr. Jacob Perkins, who is now in England, a hint of this plan of condensation, and it has there obtained him great celebrity. This fact I should not have thought it worth while to mention, had he not taken the sole merit of the invention to himself, at least I cannot hear that in his numerous public notices he has ever mentioned my name. "But to return. A small circular window, made of a single piece of thick clear glass, was neatly fitted on each of the six sides. Several pieces of lead were securely fastened to screws which passed through the bottom of the machine as well as a thick plank. The screws were so contrived, that by turning them in one direction, the pieces of lead attached to them were immediately disengaged from the hooks with which they were connected. The pieces of lunarium were fastened in like manner to screws, which passed through the top of the machine; so that by turning them in one direction, those metallic pieces would fly into the air with the velocity of a rocket. The Brahmin took with him a thermometer, two telescopes, one of which projected through the top of the machine, and the other through the bottom; a phosphoric lamp, pen, ink, and paper, and some light refreshments sufficient to supply us for some days.
