37. The latter part of the preceding numbers in the timesbeing less than those for the less weight, on May 24, 1 re-peated the experiments with this weight, of 4 oz 3 dr, to getthe times for it more exactly. The reason of this differenceis, that the arm went only 15 times round in descending onthat day, but here 35 times round, the times diminishing alittle, all the way to the end, and the times here are themeans of the last 10 rounds out of the 35, which are much,more exact.
