Reference marks.—Set off all reference marks a 5-em space when preceding words or figures. Use superior figures (1, 2, 3, etc.) for reference marks and footnotes in all cases, unless otherwise instructed. In a series of short footnotes range the reference marks, and also the first letter of the note.
Words in figure columns.—Range all words occurring in figure columns one en from rule on right; also capitalize and use full point.
Indention from rules.—An indention from a rule means so many ems in addition to the en quad used for bearing off.
Word “number.”—Spell the word “number,” referring to quantity or things, in box heads where possible. Where necessary to abbreviate or where used in connection with serial figures, use “No.”
Flush and sub heads.—Use colons after flush heads and em dashes after heads subordinate thereto.
Units of quantity.—Units of quantity to the right of reading columns and over figure columns will be spelled where possible. Where the space available demands a contraction, use the following forms: Dolls., galls., lbs., oz., bbls., cwt., yds., ft., in. (inches), doz., bush., M, sq. feet, M feet, cub. feet, kilo., kilos.
