Page 495. Delete the word “occurs” from line 40 in the left-hand column, so that lines 37-43 now read as follows: “In the interest of mechanistic realism, then, the utility of the SAA-reduced u is considered to be best explored by using a two-stage model of drop formation, in accordance with photographic evidence, this despite the emergence of later correlations (Kumar and Hartland, 1982, 1984), which regressed to an entirely empirical or curve-fitting basis.”
