 character. Two or three times, on such awaking, I went to examine the metacompass, and on one occasion found it necessary slightly to readjust the helm; the stars by which I steered having moved some second or two to the right of their proper position.

On rising, I completed the circuit which filled my vessel with brilliant light emitted from an electric lamp at the upper part of the stern, and reflected by the polished metallic walls. I then proceeded to get my breakfast, for which, as I had tasted nothing since some hours before the start, I had a hearty appetite. I had anticipated some trouble from the diminished action of gravity, doubting whether the boiling-point at this immense height above the Earth might not be affected; but I found that this depends upon the pressure of the atmosphere alone, and that this pressure was in nowise affected by the absence of gravity. My atmosphere being somewhat denser than that of the Earth, the boiling-point was not 100°, but 101° Cent. The temperature of the interior of the vessel, taken at a point equidistant from the stove and from the walls, was about 5° 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;
