"Our interlude is over and we will go on with the performance. We are going to burn several substances in oxygen and watch their manner of burning. First comes sulphur. "Adopting the method you saw employed when we tried in vain to make phosphorus and sulphur burn in a bottle filled with nitrogen, I make a little cup out of a bit of broken earthenware, and bend the end of an iron wire into a circle for holding this cup. The iron wire is then passed through a large cork stopper that will serve to hold it in place in the bottle rather than to stop up the bottle itself. Hence it does not matter much if the cork is too large for the bottle. A small disk of stout cardboard laid over the mouth of the bottle would answer just as well. The end of the wire, projecting above the supporting cork or cardboard, will serve as a handle for lowering or raising the cup so as to bring it into or near the center of the bottle, in the midst of the supply of oxygen." Having finished these preparations, Uncle Paul carefully took up one of the large bottles in reserve, together with the glass full of water in which it stood and which served to close its mouth. These, without disturbing their relative position, he carried to the bowl, and there, under water, the glass was removed and replaced by the palm of the hand applied to the bottle's mouth.
