The weight of every ball was 16 oz 14 dr. The firstcharge of powder was 4 ounces, and all the rest 16 ounces.
The Gun was n° 3 —Began first with its own weightonly ; then at n* 5 put on one pair of the usual weights ; atn° 7 the other pair ; and lastly at n° 9 fixed on some extraweights. But the result shows that the velocity of the ballis the same with all of them.
The Pendulum as left hanging since yesterday.
The value of i, or medium among the points struck theselast two days, is 88’2.
