from an accumulator on board. The car, of course, would be hermetically
sealed, but it would have doors and windows which could be opened at
pleasure. In open space it would be warmed and lighted by the sun, and
in the shadow of a planet, if need were, by coal-gas and electricity.
In either case, to temper the extremes of heat or cold, the interior
could be lined with a non-conductor. Liquefied oxygen or air for
breathing, and condensed fare would sustain the inmates; and on the
whole they might enjoy a comfortable passage through the void, taking
scientific observations, and talking over their experiences."

_G_. "It would be a novel observatory, quite free from atmospheric
troubles. They might be able to make some astronomical discoveries."

_I_. "A novel laboratory as well, for in space beyond the attraction of
the earth there would be no gravity. The travellers would not feel a
sense of weight, but as the change would be gradual they would get
accustomed to it, and suffer no inconvenience."

_G_. "They would keep their gravity in losing it."

_I_. "The car, meeting with practically no resistance in the ether,
would tend to move in the same direction with the same velocity, and
anything put overboard would neither fall nor rise, but simply float
alongside. When the car came within the sensible attraction of the moon,
its velocity would gradually increase as they approached each other."

_G_. "Always supposing the aim of the gun to have been exact. You might
hit the moon, with its large disc and comparatively short range,
provided no wandering meteorite diverted the bullet from its course; but
it would be impossible to hit a planet, such as Venus or Mars, a mere
