METHOD OF MOULDING PHOSPHORUS INTO CYLINDERS. 157

into a vessel of cold water, and when it is thoroughly cooled,the cork is taken out and the phosphorus thrust out of its mouldw ith a piece of wood and then preserved in water.

Pelletier invented another method which is as follows:

Take a few tubes of any length, the apertures of which are ofsuch a size that they can be exactly closed with the extremity ofthe finger. Melt the phosphorus in boiling water, and apply toit one of the ends of the tube, while you hold the other in yourmouth; make a short inspiration that the phosphorus may ascenda little way in the tube; stop the inspiration when the phospho-rus has risen a sufficient height and close the extremity of thetube with the fore finger and immerse it in a bason of coldW'ater. The phosphorus will soon become fixed and by a slightshake mav be separated from the tube.

The combustibility and luminous property of phosphorus have •given birth to various amusing experiments which w r e shall in-sert, for they are well calculated to evince some of its charac-teristic properties in a pleasing manner.
