   * When the number of seconds for the middle wire is greater [th?]an 30, subtract 30 from it and put the difference in the column, [E?]xcess[superscript]"[/superscript]. Then add the numbers of seconds of the other wires in [illegible?]irs, taking the number for D[subscript]2[/subscript] with that for D[subscript]4[/subscript], etc., and place [the?] result in the Excess column opposite the lower number of the [illegible?][i?]; but when the sum is greater than 60, subtract 60 from it. Thus [a?]verage the excesses and add the mean to 30 for the time on D[subscript]3[/subscript]. When [t?]he number of seconds for D[subscript]3[/subscript] is less than 30, place it in the Excess [c?]olumn and stands and proceed as before.
