The thermometer and the barometer were all right, except one self-recorder of which the glass had got broken.

An excellent aneroid barometer, taken safe and sound out of its wadded box, was carefully hung on a hook in the wall.

It marked not only the pressure of the air in the Projectile, but also the quantity of the watery vapor that it contained.

The needle, oscillating a little beyond thirty, pointed pretty steadily at "_Fair_." The mariner's compasses were also found to be quite free from injury.

It is, of course, hardly necessary to say that the needles pointed in no particular direction, the magnetic pole of the Earth being unable at such a distance to exercise any appreciable influence on them.
