It is only necessary topour previously into the glass two or three drops of hydro-chloric acid, and to moisten the bottom of the saucer witha few drops of ammonia. These two liquids are unper-ceived by the spectators, but as soon as the saucer isplaced over the glass, they unite in forming white fumesof hydrochlorate of ammonia, which bear a complete re-semblance to the smoke of tobac

This experiment excited the greatest astonishmentamong the spectators present on the occasion, but under-standing something of chemistry myself, I easily guessedat the solution of the mystery. The same result isobtained in a course of chemistry in a more simple manner,and without any attempt at trickery, by placing the open-ing of a bottle of ammonia against the opening of anotherbottle containing hydrochloric
