    one side of the stopper, and the ends (¢, d) being carried along the groove to the opposite side, are tied there, as represented in fig. 321. The end (d) of the cord is now passed through the loop (a), and the two ends being brought together, are tied as represented at (7) fig. 822. The cord being thus secured to the stopper, the bottle is, in the next place, to be suspended as shewn in fig. 322, by placing the cord over an _hori- zontal bar of sufficient strength g / and firmness to bear a powerful ‘ jerk. It must be so adjusted that the cords on each side of the stopper shall be of equal length, and the weight of the bottle will then ensure its maintaining a ver- tical position. An assistant places his hand over the part of the cord in contact with the horizontal bar to prevent it from slipping to either side, and the operator, having wrapped a cloth around the neck and shoulder of the bot- tle, and grasped this part with his two hands, raises the bottle a few inches, and then pulls it down with a jerk. This operation | is repeated, commencing with ( | slight force, and increasing the Ne power with each successive jerk, 7% Sek de until the extraction of the stopper Pee Rumi in an Gb pRney is effected. If care be taken to maintain the vertical position of the bottle, and of the direction of the jerk, there will be little danger of breaking the stopper. I have found this a more effectual method of extracting the stoppers of smelling-bottles, and of small bottles generally, than any other that I am acquainted with. | Fig, 322.
