[Sidenote: Lead Weights placed at first in the Car, to prevent any Fatigue in holding the Lines, and the Necessity of weighing, unless at the Time of Ascent, to determine the Power of Levity.] 24. It may be proper to mention that Mr. Baldwin being resolved to prevent the disagreeable Circumstances of being _weighed_ in the Presence of Thousand spectators, at a Time when it is uncertain whether the Balloon has _acquired_ a sufficient Degree of Levity to raise his own Weight, together with the Instruments, Provisions, Ballast, and other Articles, all which are known or easily calculated; finding some Days before, his own Weight, and having calculated the rest as under[7]; he ordered his Servant, on the Day of the Excursion, to bring Lead Weights equal to the _Sum total_, with an overplus Weight of 10lb. for Levity of Ascent, and place them _gradually_ in the Car, attached for that Purpose to the Balloon, soon after the Inflation began. By which Means the Gentlemen who held the Cords were quite at Ease: nor was there Occasion to tye the Lines during the Inflation, to Posts fixed in the Circumference of the Circle; nor consequently to _cut them_ afterwards. But it will be seen that Mr. Lunardi inflated the Balloon in a superior Manner. 25. All Things being thus prepared, Mr. Baldwin stepped into the Car: and finding, that, besides his own Weight, the Provisions, Articles, Ballast, &c. the Balloon woud support an additional Weight, and _still_ rise with superior Levity; Mr. Lunardi put in 12lb. of additional Ballast, and _guessed_ the encreased Levity at 10lb. more. Additional { Ballast 12 { Levity 10 ——— 22 Added to the 234 ——— Make the Sum 256lb. All which added to the Weight of the Balloon, _by Information only_, as follows: Balloon varnished 113 Netting and Cords 18 Car and Hoops 24 Mended and added Parts 5 Grapple and Cable 4 ——— 164 With the 256 Make the total Levity of the Gass to produce an Equilibrium, equal to 420lb. The Weight of a Quantity of Air equal in Bulk to the Balloon, being secluded; and the Gass substituted in its Room. [Sidenote: Weight of Articles.] 26. The Calculation of the Weight of Articles was, as follows: Pounds Articles. Averd. Ounces. 1. Eight coloured Bladders[8] (Section 13, Art. 18) 1 – 0 2.
