, such error would influence the final value of
by an inappreciable amount. The first 23 drops of [Table X] represent such observations. It will be seen that they show slightly greater consistency than do the remaining drops in the table and that the correction-term reductions for these drops all lie between 1.3 per cent (drop No. 1) and 5.6 per cent (drop No. 23), so that even though
were in error by as much as 3 per cent (its error is actually not more than 1.5 per cent),
would be influenced by that fact to the extent of but 0.1 per cent. The mean value of
obtained from the first 23 drops is
