essential connection with the sentence, and could be done without. They
should be used as little as possible for they show that something is
being brought into a sentence that does not belong to it.

(1) When the unity of a sentence is broken the words causing the break
should be enclosed in parenthesis: "We cannot believe a liar (and Jones
is one), even when he speaks the truth."

(2) In reports of speeches marks of parenthesis are used to denote
interpolations of approval or disapproval by the audience: "The masses
must not submit to the tyranny of the classes (hear, hear), we must show
the trust magnates (groans), that they cannot ride rough-shod over our
dearest rights (cheers);" "If the gentleman from Ohio (Mr. Brown), will
not be our spokesman, we must select another. (A voice,--Get Robinson)."

When a parenthesis is inserted in the sentence where no comma is
required, no point should be used before either parenthesis. When
inserted at a place requiring a comma, if the parenthetical matter
relates to the whole sentence, a comma should be used before each
parenthesis; if it relates to a single word, or short clause, no stop
should come before it, but a comma should be put after the closing
parenthesis.


The _Quotation marks_ are used to show that the words enclosed by them
are borrowed.

(1) A direct quotation should be enclosed within the quotation marks:
Abraham Lincoln said,--"I shall make this land too hot for the feet of
slaves."
