192. As the series of decreasing velocities are not quiteregular, the numbers are altered here and there by certainvery small quantities, which, without materially affectingthe whole velocity itself, has the effect of making the seriesbecome regular, and so the more easily leading to the regu-lar law of resistance. These corrected, or regulated veloci-ties, are set in columns, each immediately after its corre-sponding column of irregular or calculated velocity; andthose regular columns being extracted from the rest, andbrought together by themselves, with their correspondentdistances and differences, will stand as follows.
