Fractions standing alone are expressed in figures, even at the beginning of a line, but not at the beginning of a footnote.
Headnotes should be set lowercase, but not smaller than 6 point, bracketed, and period omitted at end, even if the statement is a complete sentence; but periods should not be omitted internally if required by sentence structure.
Headnotes are repeated under continued heads but the word Continued is not added to the headnote.
The indention of subentries is determined by the width of the stub or reading column. Subentries in columns more than 15 ems wide are indented in 2-em units; in columns 15 ems or less, with short entry lines and few overruns, 2-em indentions are also used. All overruns are indented 1 em more.
Subentries in columns of 15 ems or less are indented in 1-em units. Overruns are indented 1 em more.
All total (also mean and average) lines are indented 3 ems. In very narrow stub columns, total lines may be reduced to 1- or 2-em indentions, depending on length of line.
Where overrun of item above conflicts, the total line is indented 1 em more. Runovers of total lines are also indented 1 em more.
It is not necessary to maintain uniform indention of the word Total throughout the same table. The word Total is supplied when not in copy.
