he words _Lower-case_, written in the margin.

_Where words have been erroneously struck out_, or are otherwise wished
to remain, dots should be placed under them, and the word _Stet_ (_let
it stand or remain_) written in the margin.

_Where the Punctuation requires to be altered_, the Semicolon, Colon, or
Period, should be marked and encircled in the margin, a line being drawn
at the word at which either is to be placed, as in No. 15.--16 describes
the manner in which the hyphen and ellipsis line are marked; and 17,
that in which the Apostrophe, Inverted Comma, the Star, and other
References, and Superior Letters, and Figures, are marked for insertion.
Notes, if added, should have the word _Note_, with a Star, and a
corresponding Star at the word to which they are referred.

_Where letters or lines are altered_, they are noticed by drawing lines
before and after them, as in No. 18.

A little practice will soon render the use of these Marks familiar.

It has been before observed, that Correcting the Press, so far as the
Printers are concerned, is an extremely troublesome, and to them, the
most unpleasant part of their business. It occupies much more time than
could be supposed, and consequently occasions an Expense which the mere
alteration of a few Words in a Page would perhaps scarcely be thought
sufficient to justify. But when it is considered that every alteration
disturbs the whole adjoining mass of Type, and may do so to the end of
the Page, or several Pages, it will be less difficult to perceive the
reason of the well ascertained fact, that Printers always greatly prefer
being employed in the Setting, rather than in the Correcting department
of their office.

It is not uncommon for Authors, unaware of these circumstances, to
deliver their Manuscript for the Press, in a very unfinished state; and
in some instances, as if they actually considered that they could not
satisfactorily Correct their Work, until they saw it in Print--an error
which it would probably only require them to combat to overcome: it
should, however, in all such cases, be distinctly understood, that the
Expenses of Correcting will, if considerable, unavoidably enhance that
of the Printing, and this in a ratio that would very naturally surprise
those unacquainted with the subject.

All errors which are not in the Manuscript, are considered as errors of
the Press; the correction of which devolves on the Printer. Indeed, no
proof should be s
