When the ampersand may be used

MARKS OF REFERENCE

The seven marks of reference made for foot-notes * † ‡ ‖ § ¶ ☞ are seldom used in the best books. They have been condemned as too few for many notes on the same page, as well as for their want of regularity. Some are too weak and others are too bold. Superior figures and letters [1] are preferred: the figures for the texts of ordinary books; the letters for cut-in notes of pocket Bibles, and for other notes when many in number.

THE AMPERSAND

The ampersand & is proper for the exact rendering of the signature or the authorized business name of a firm of copartners or a corporation, as in R. Hoe & Co. or New York & Harlem Railroad Co. It is in this form that such names are used in newspapers and pamphlets, and even in ordinary books. When many firm names are printed in a column, as in signatures, the & and the Co. should be retained as the true copy of each signature.[2]

  1. The letters are also used as signs or symbols in text-books of sciences to refer to many different things. In music and geometry, roman capital letters are preferred; in algebra, lower-case italic letters; in astronomy, lower-case Greek characters; in -chemistry, capitals, figures, and lower-case combined.
  2. Some publishers and authors require that they shall appear in a standard book as R. Hoe and Company and New York and Harlem Railroad Company. It is, however, impossible here to draw a line of distinction between the ordinary and the standard book. The compositor should follow his copy.
