the Balloon, it appear’d no bigger than a Walnut. I write this at 7 in the Evening. What became of them is not yet known here. I hope they descended by Day-light, so as to see & avoid falling among Trees or on Houses, and that the Experiment was completed without any mischievous Accident which the Novelty of it & the want of Experience might well occasion. I am the more anxious for the Event, because I am not well inform’d of the Means provided for letting themselves gently down, and the Loss of these very ingenious Men would not only be a Discouragement to the Progress of the Art, but be a sensible Loss to Science and Society.
I shall inclose one of the Tickets of Admission, on which the Globe was represented, as originally intended, but is altered by the Pen to show its real State when it went off. When the Tickets were engraved, the Car was to have been hung to the Neck of the Globe, as represented by a little Drawing I have made in the Corner A. I suppose it may have been an Apprehension of Danger in straining too much the Balloon or tearing the Silk, that induc’d the Constructors to throw a Net over it, fix’d to a Hoop which went round its Middle, and to hang the Car to that Hoop, as you see in Fig. B.
Tuesday Morning, Dec. 2. I am reliev’d from my Anxiety, by hearing that the Adventurers descended well near l’Isle Adam, before Sunset. This Place is near 7 Leagues from Paris. Had the Wind blown fresh, they might have gone much farther.
If I receive any farther Particulars of Importance I shall communicate them hereafter.
P. S. Tuesday Evening.
Since writing the above, I have receiv’d the printed Paper & the Manuscript, containing some Particulars of the Experiment, which I enclose.—I hear farther, that the Travellers had perfect Command of their Carriage, descending as they pleas’d by letting some of the inflammable Air escape, and rising again by discharging some Sand; that they descended over a Field so low as to talk with Labourers in passing and mounted again to pass a Hill. The little Balloon falling at Vincennes, shows that mounting higher it met with a Current of Air in a contrary Direction: An Observation that may be of use to future aerial Voyagers.

(SOME PARTICULARS OF THE SECOND VOYAGE.)
Mr. Le Chevalier de Cubière qui a suivi la marche du Globe est arrivé chez M. Charles hier à 10 heures ¼ du Soir et a dit, Que les Voyageurs étoient descendus lentement et volontairement à trois heures ¾ dans les Marais de Nesle et d’Hebouville, une lieue et demie après l’Isle Adam. Ils y ont été accueillis par Mrs. le Duc de Chartre et Fitz James, qui après les avoir embrassés, ont signé le Procès verbal de lieu et d’heure. Beaucoup d’habitants de la campagne et le curé de Nesle et d’Hebouville se sont aussi trouvés à leur arrivée.
Les Voyageurs ont assuré n’avoir éprouvé que des Sensations agréables dans leur traversée. Mr. Robert étant sorti du Char, et aidé de quelques Paysans, se disposoit à remplacer sa Pesanteur avec de la Terre; mais M. Charles voulant profiter du peu de Jour qui lui restoit, pour faire encore quelques observations, impatienté de la Lenteur de cette operation, a repris son Vol à 4 heures et ¼, avec un excédant de Légèreté d’environ 100 Livres par une Ascension droite et une rapidité telle qu’en peu de tems le Globe s’est trouvé hors de vue. La Chute du Jour l’a déterminé à redescendre une lieue et ½ plus loin, aux environs de Fouroy.
La Machine n’a éprouvé aucun
