DUMMY. A pocket-book; a portmonnaie. "Frisk the dummy of the screens, ding it and bolt; they are crying out beef," take out the money and throw the pocket-book away; run, they are crying, stop thief!
DUN. A very importunate creditor. Dunny, in the provincial dialect of several counties in England, signifies deaf; to dun, then, perhaps may mean to deafen with importunate demands; it may have been derived from the word donnez, which signifies give. But the word undoubtedly originated in the days of one Joe Dun, a famous bailiff of the town of Lincoln, England, who was so extremely active and dexterous in his business, that it became a proverb, when a man refused to pay, to say, "Why don't you Dun him?" that is, send Dun after him. Hence it became a cant word, and is now as old as the days of Henry VII. Dun was also the name for the hangman, before that of Jack Ketch.
"And presently a halter got,
Made of the best strong hempen teer,
And ere a cat could lick her ear,
Had tied it up with as much art,
As Dun himself could do for's heart."
Cotton's Virgil Trav. Book IV.
