attending its inhalation, while, upon removal to the denser strata near the earth, he might endure tortures of a similar nature to those I had so lately experienced.  It has since been to me a matter of deep regret that an awkward accident, at this time, occasioned me the loss of my little family of cats, and deprived me of the insight into this matter which a continued experiment might have afforded.  In passing my hand through the valve, with a cup of water for the old puss, the sleeves of my shirt became entangled in the loop which sustained the basket, and thus, in a moment, loosened it from the bottom.  Had the whole actually vanished into air, it could not have shot from my sight in a more abrupt and instantaneous manner.  Positively, there could not have intervened the tenth part of a second between the disengagement of the basket and its absolute and total disappearance with all that it contained.  My good wishes followed it to the earth, but of course, I had no hope that either cat or kittens would ever live to tell the tale of their misfortune.

“At six o’clock, I perceived a great portion of the earth’s visible area to the eastward involved in thick shadow, which continued to advance with great rapidity, until, at five minutes before seven, the whole surface in view was enveloped in the darkness of night.  It was not, however, until long after this time that the rays of the setting sun ceased to illumine the balloon; and this circumstance, although of course fully anticipated, did not fail to give me an infinite deal of pleasure.  It was evident that, in the morning, I should behold the rising luminary many hours at least before the citizens of Rotterdam, in spite of their situation so much farther to the eastward, and thus, day after day, in proportion to the height ascended, would I enjoy the light of the sun for a longer and a longer period.  I now determined to keep a journal of my passage, reckoning the days from one to twenty-four hours continuously, without taking into consideration the intervals of darkness.

“At ten o’clock, feeling sleepy, I determined to lie down for the rest of the night; but here a difficulty presented itself, which, obvious as it may appear, had escaped my attention up to the very moment of which I am now speaking.  If I went to sleep as I proposed, how could the atmosphere in the chamber be regenerated in the interim?  To breathe it for more than an hour, at the farthest, would be a matter of impossibility, or, if even this term could be extended to an hour and a quarter, the most ruinous consequences might ensue.  The consideration of this dilemma gave me no little disquietude; and it will hardly be believed, that, after the dangers I had undergone, I should look upon this business in so serious a light, as to give up all hope of accomplishing my ultimate design, and finally make up my mind to the necessity of a descent.  But this hesitation was only momentary.  I reflected that man is the
