[A Key-Pistol.~\ This mere piece of ingenuity, so 

 pleasing to certain mechanics in working out mechani 

 cal trinkets, might be effected by causing the removal

 he determined, and when it struck the determined 

 hour, it struck fire likewise out of a flint, which fell 

 among tinder, to light him a candle : it was the inven 

 tion of one Caravagio of Sienna in Italy.&quot;
