THE PERIOD
The period, or full stop, marks the end of a declarative sentence. As a sign it has several other uses which will appear in the paragraphs following.
Rules for the Use of the Period
1. At the end of every sentence unless interrogative or exclamatory.
2. After abbreviations.
Nicknames, Sam, Tom, etc., are not regarded as abbreviations.
The metric symbols are treated as abbreviations but the chemical symbols are not. M. (metre) and mg. (milligram) but H{2}?O and Na?Cl.
Per cent is not regarded as an abbreviation.
The names of book sizes (12mo 16mo) are not regarded as abbreviations.
The period is now generally omitted in display matter after
Running heads, Cut-in side-notes, Central head-lines, Box heads in tables, Signatures at the end of letters.
The period is omitted
After Roman numerals, even though they have the value of ordinals.
After MS and similar symbols.
In technical matter, after the recognized abbreviations for linguistic epochs. IE (Indo-European), MHG (Middle High German)
and after titles of well-known publications indicated by initials such as AAAPS (Annals of the American Academy of Political Science).
When a parenthesis forms the end of a declarative sentence the period is placed outside the parenthesis, as in the preceding example. A period is placed inside a parenthesis only in two cases.
1. After an abbreviation.
This was 50 years ago (i.e. 1860 A.D.)
2. At the end of an independent sentence lying entirely within the parenthesis.
Lincoln was at the height of his powers in 1860 (He was elected to the presidency at this time.)
When a sentence ends with a quotation, the period always goes inside the quotation marks.
I have just read DeVinne's "Practice of Typography."
The same rule applies to the use of the other low marks, comma, semicolon, and colon, in connection with quotation marks. Unlike most rules of grammar and punctuation, this rule does not rest on a logical basis. It rests on purely typographic considerations, as the arrangement of points indicated by the rule gives a better looking line than can be secured by any other arrangement.
Other Uses of the Period
1. The period is used as a decimal point.
2. The period is used in groups, separated by spaces, to indicate an ellipsis.
He read as follows: "The gentleman said?.?.?.?. he was there and saw?.?.?.?.?the act in question."

THE DASH
The dash is a very useful mark which has been greatly overworked by careless writers. It is very easy to make in manuscript and serves as a convenient cover for the writer's ignorance of what point should properly be used.
The conspicuousness of the dash makes it a very useful mark for guiding the eye of the reader to the unity of the sentence. It is particularly useful in legal pleadings where there is much repetition of statement and great elaboration of detail. In such cases commas, semicolons, and even parentheses are so multiplied that the relation of the clauses is lost sight of. The confusion thus arising may often be cleared up by intelligent use of the dash.
The dash is sometimes used to connect a side heading with the text that follows, or to connect the end of that text with the name of the writer.
A RULE FOR PEACE.--If it be possible, as much as lieth in you, live peaceably with all men.--St. Paul.
The dash is sometimes used in catalogue work as a ditto mark.

French printers use the dash in printing dialogue as a partial substitute for quotation marks. Quotation marks are placed at the beginning and end of the dialogue and a dash precedes each speech. This form is used even if the dialogue is extended over many pages.
Rules for the Use of the Dash
1. To mark abrupt changes in sentiment and in construction.
Have you ever heard--but how should you hear?
2. To mark pauses and repetitions used for dramatic or rhetorical effect.
They make a desert, and call it--peace. Thou, great Anna, whom three states obey, Who sometimes counsel takes--and sometimes tea.
3. To express in one sentence great contrariety of action or emotion or to increase the speed of the discourse by a succession of snappy phrases.
She starts--she moves--she seems to feel The thrill of life along her keel.
In this connection DeVinne gives the following excellent example from Sterne:
Nature instantly ebbed again;--the film returned to its place;--the pulse fluttered,--stopped,--went on,--throbbed,--stopped again,--moved,--stopped,--Shall I go on?--No.
Attention may be called to Sterne's use of the semicolon and the comma with the dash, a use now obsolete except in rare cases.
4. To separate the repetition or different amplifications of the same statement.
The infinite importance of what he has to do--the goading conviction that it must be done--the dreadful combination in his mind of both the necessity and the incapacity--the despair of crowding the concerns of an age into
