RULE XXIV.—INTERJECTIONS.
Interjections have no dependent construction; they are put absolute, either alone, or with other words: as, "O! let not thy heart despise me."—Dr. Johnson. "O cruel thou!"—Pope, Odys., B. xii, l. 333. "Ah wretched we, poets of earth!"—Cowley,
"Ah Dennis! Gildon ah! what ill-starr'd rage
Divides a friendship long confirm'd by age?"
Pope, Dunciad, B. iii,
