Place also a few pieces of bundle wood upright around the flask, so as to prevent it from touching the sides. Then connect the two tubes, as seen in the figure, by means of a small piece of indiarubber tubing. Pour into the pan water in such quantity that, in boiling, its level will remain below the level of the methylated spirit in the flask.
