h, [double dagger
character][double dagger character]; and so on. But it is better, in
cases where the notes are so numerous, to use other means of
reference.

(2) Figures: either within parentheses, as (1), (2), (3), &c.; or,
more usually, printed in the raised or "superior" form, as ^{1} squared
cubed, &c. Sometimes the first note in each page is marked;^{1} but it
is now common, in books divided into chapters, to mark the first note
in each chapter with ^{1} and then go on with continuous numbers to the
end of the chapter.

"Superior" figures are now the most usual marks of reference in
English books.

(3) Letters; which also may either be placed within parentheses or be
printed in "superior" form: (a), (b), (c), &c., or ^{a} ^{b} ^{c}, &c.
Italic letters are sometimes used. As a rule the first note in each
page is marked (a) or ^{a}. If in one page there are more notes than
there are letters in the alphabet (which sometimes happens), we go to
(aa), (bb), (cc), &c., ^{aa} ^{bb} ^{cc}. The letter "j" is often
omitted.

It is less common to make the letters continuous from page to page.

The sign, whatever it may be, is placed at the beginning of the note,
and also in the text immediately after the part to which the note
refers. The note may refer to a whole sentence, to a part of a
sentence, even to a single word; the sign is placed as the case may
be, at the end of the sentence, at the end of the part referred to, or
after the single word.

HOW TO CORRECT A PRINTER'S PROOF

[Illustration]

EXPLANATION

1. Where a word is to be changed from small letters to capitals, draw
three lines under it, and write _caps._ in the margin.

2. Where there is a wrong letter, draw the pen through it, and make
the right letter opposite in the margin.

3. A letter turned upside down.

4. The substitution of a comma for another point, or for a letter put
in by mistake.

5. The insertion of a hyphen.

6. To draw close together the letters of a word that stand apart.

7. To take away a superfluous letter or word, the pen is struck
through it and a round top _d_ made opposite, being the contraction of
_deleatur_='expunge.'

8. Where a word has to be changed to Italic, draw a line under it, and
write _Ital._ in the margin; and where a word has to be changed from
Italic to Roman, write _Rom._ opposite.

9. When words are to be transposed, three ways of marking them are
shown; but they are not usually numbered
