26. Having now obtained a long series of actuatingweights and velocities, with both sides of the hemisphereforemost, and with the lead alone ; a set of the correspond-ing ones are extracted from the whole, and arranged toge-ther, in the first of the following tables ; where the first co-lumn contains the several rates of velocity, from 3 to 20 feetin a second, differing always by 1; the next 3 columns con-taining the correspondent weights acting on the axis, ofT044 radius, for both sides of the body and the lead. Butthe differences of these not being perfectly regular, thoughvery nearly so; correcting therefore those differences hereand there, by some veiy small fractions, and by them the few
