The glass cylinder (fig. 292) can be con-verted by a very simple plan into a good andabsolutely clean syringe, if it only has throughouta uniform calibre. A plug of vulcanite is screwedon to the twirling stick (fig. 295), the diameter ofwhich is smaller than the lumen of the cylinderby a few millimetres, and whose sides are some-what concave. Wadding, jute, gauze, or cottonwick is wrapped round, and tied on to it by apiece of protective silk. A piston is thus formed,which is absolutely clean and accurately fills thelumen of the cylinder.
