ce of gravity. My atmosphere being somewhat denser than that of
the Earth, the boiling-point was not 100 deg., but 101 deg. Cent. The
temperature of the interior of the vessel, taken at a point
equidistant from the stove and from the walls, was about 5 deg. C.;
unpleasantly cool, but still, with the help of a greatcoat, not
inconveniently so. I found it absolutely impossible to measure by
means of the thermometers I had placed outside the windows the cold of
space; but that it falls far short of the extreme supposed by some
writers, I confidently believe. It is, however, cold enough to freeze
mercury, and to reduce every other substance employed as a test of
atmospheric or laboratory temperatures to a solidity which admits of
no further contraction. I had filled one outside thermometer with
spirit, but this was broken before I looked at it; and in another,
whose bulb unfortunately was blackened, and which was filled with
carbonic acid gas, an apparent vacuum had been created. Was it that
the gas had been frozen, and had sunk into the lower part of the bulb,
where it would, of course, be invisible? When I had completed my meal
and smoked the very small cigar which alone a prudent consideration
for the state of the atmosphere would allow me, the chronometer showed
10 A.M. It was not surprising that by this time weight had become
almost non-existent. My twelve stone had dwindled to the weight of a
small fowl, and hooking my little finger into the loop of a string
hung from a peg fixed near the top of the stern wall, I found myself
able thus to support my weight without any sense of fatigue for a
quarter of an hour or more; in fact, I felt during that time
absolutely no sense of muscular weariness. This state of things
entailed only one inconvenience. Nothing had any stability; so that
the slightest push or jerk would upset everything that was not fixed.
However, I had so far anticipated this that nothing of any material
consequence was unfixed, and except that a touch with my spoon upset
the egg-cup and egg on which I was about to breakfast, and that this,
falling against a breakfast cup full of coffee, overturned that, I was
not incommoded. I managed to save the greater part of the beverage,
since, the atmospheric pressure being the same though the weight was
so changed, lead, and still more china or liquid, fell in the
Astronaut as slowly as feathers in the immediate vicinity of the
Earth. Still it was a novel experience
