Friendship's the privilege / Of private men. N. Tate.
Friendship's the wine of life; but friendship new is neither strong nor pure. Young.
Friendships which are born in misfortune are 50 more firm and lasting than those which are formed in happiness. D'Urfey.
Frigidam aquam effundere—To throw cold water on a business.
Frisch gewagt ist halb gewonnen—Boldly ventured is half done (won). Ger. Pr.
From a bad paymaster get what you can. Pr.
From a closed door the devil turns away. Port. Pr.
From camp to camp, through the foul womb of night, / The hum of either army stilly sounds, / That the fix'd sentinels almost receive / The secret whispers of each other's watch; / Fire answers fire, and through their paly flames / Each battle sees the other's umber'd face; / Steed threatens steed in high and boastful neighs, / Piercing the night's dull ear, and from the tents / The armourers, accomplishing the knights, / With busy hammers closing rivets up, / Give dreadful note of preparation. Hen. V., iv. (chorus).
From every moral death there is a new birth; / in this wondrous course of his, man may indeed linger, but cannot retrograde or stand still. Carlyle.
