The simplest form of lamp is shown in Fig. 210, holding abouta pint, and having a Avick three-fourths of an inch or one inchin diameter. As accidentssometimes occur from the flamecommunicating with the explo-sive mixture of air and alco-holic vapor in the body of thelamp, it is prudent to make asafety-lamp by connecting thewick-tube with the body of thelamp by a small tube, whiclishall be, under all circum-stances, full of alcohol. Fig,211 represents such a lamp, provided the wick is not permitted Fig. G72 SOLDERING. to run down as low as the horizontal tube. The top of the wicktube should be beveled off in a direction just the reverse of that Fig. 211.
