The operator being provided with a bottle of finely prepared rotten stone, cover the mouth of the bottle with a piece of thick paper, this perforated with a pin so that the rotten stone can be dusted on the plate. Fasten the plate on the holder, take the rotten stone (Becker's can always be depended upon), and dust on lightly until the surface is freely covered; now drop on the plate's surface a few drops of an alcoholic solution.*英文原著 · 《American Hand Book of the Daguerreotype》
The streets were empty. There were lights only in the barber shop where one patron was being lathered while two mandolins and a guitar gave a correct imitation of two house-flies and a bluebottle in Riley's where, in default of other occupation, Mr. Riley was counting up; in Oesterle's, where a hot discussion was going on as to whether Christopher Columbus was a Dutchman or a Dago, and in Miller's, where Tom Ball was telling Tony, who impassively wiped the perforated brass plate let into the top of the bar, that he, Tom Ball, "coul' lick em man ill Logan coun'y."英文原著 · 《Back Home》

At this period he devised his electric pen, an ingenious device for making copies of a document. It consists essentially of a needle, rapidly jogged up and down by means of an electro-magnet actuated by an intermittent current of electricity. The writing is traced with the needle, which perforates another sheet of paper underneath, thus forming a stencil-plate, which when placed on a clean paper, and evenly inked with a rolling brush, reproduces the original writing.英文原著 · 《Heroes of the Telegraph》
In 1847 Bain devised an automatic method of playing on wind instruments by moving a band of perforated paper which controlled the supply of air to the pipes; and likewise proposed to play a number of keyed instruments at a distance by means of the electric current. Both of these plans are still in operation.英文原著 · 《Heroes of the Telegraph》
