Acidulated Solution.--This solution is used for cleaning the surface of the Daguerreotype plate. It has the property of softening the silver, and bringing it to a state in which it is very susceptible of being either oxidized or iodized, hence it contributes to increase the sensibility of the plate. The proportions are to one drop of acid add from 15 to 20 drops of water, or make the solution about like sharp vinegar to the taste.英文原著 · 《American Hand Book of the Daguerreotype》

"I am assisting at the wake," said he, "of the only nation on earth that ever did me a good turn. As one gentleman to another, I am ratifying and celebrating the foreign policy of the late Jefferson Davis, as fine a statesman as ever settled the financial question of a country. Equal ratio--that was his platform--a barrel of money for a barrel of flour--a pair of $20 bills for a pair of boots--a hatful of currency for a new hat--say, ain't that simple compared with W. B's little old oxidized plank?"英文原著 · 《Roads of Destiny》
