These foot-notes often appear in the following form:
130-2. 5. Schaff, Morris: The Battle of the Wilderness.
Foot-notes are often extensively used in scientific periodicals and books; and the larger establishments that print such matter usually have their style-cards, which should be followed by authors submitting manuscripts to such establishments.
The lower-case italic letters, “a,” “b,” and “c,” and sometimes the superior letters, are used to indicate the first, second, and third parts of a verse, paragraph, or page referred to by an accompanying figure. For instance, Romans vi, 5a means the first part of verse 5 of Romans vi.
STAR, DAGGER, ETC.
Because of the clumsy appearance of these marks, and because of the inconvenience they cause in the mechanical make-up of printed matter, they are used sparingly; but they are quite indispensable in tabulated matter, scientific works, etc.
If several of these marks are required on a page, they follow the following order: star, dagger, double dagger, section, parallel lines, paragraph.
MISCELLANEOUS
The word cent in per cent is now generally written without a period.
Etc. is preferable to &c. when used for “and others” or “and so on”; but not a few good writers use the latter for this purpose.
