The Gun n° 2. In the last 5 rounds it had about 10depression.
The Pbndulum the same as left hanging since yesterday.After the experiments were concluded , to-day, it weighed694 lb.—The plugs weighed 1 oz per inch.
The weight of balls and plugs lodged in the block, theselast three days, was 36 lb ; which added to 663, the weightat the beginning, makes 699 : but it weighed .at the endonly 694 ; so that it lost 5 lb of its weight in the 4 days, or1-t.lb per day on a medium.
