Note 407 — PHARMACOLOGIA. (continued 2)
Reading edition
Should the operator be unable to procure a spirit lamp, a very convenient substitute may be provided in the following manner. Let a piece of tin plate, about an inch long, be coiled up into a cylinder of about ⅜ths of an inch in diameter, and, if the edges be well hammered, it is not necessary to use solder. Perforate a cork, previously fitted to a phial, and put a cotton wick through the short tin tube, and the tube through the cork. The lamp is now complete, and will afford a strong flame, taking care of course not to prevent the rise of the spirit by fitting the cork too closely.
