Rule XIV.—In personification it is usual to capitalize the personified words.

Examples:—
Vice is a monster; smiling Spring.
The Voice of Nature; but: true to nature.

ABBREVIATIONS, CONTRACTIONS AND DEGREES

Military or naval and some professional titles preceding names are nearly always abbreviated; as Capt. Jones, Dr. Brown, Rev. Dr. Smith.

Titles of collegiate degree are abbreviated; as, William Lee, Ph. D., LL. D.

In general writing, it is better to avoid abbreviation as far as possible.

PUNCTUATION

Punctuation is the indication, by means of stops, of the different pauses necessary to show the meaning of a sentence.

Stops, therefore, are used to elucidate the meaning of words in their relation to other words.
