We will now put that on one side, and take some other substance; but we must limit our experiments, for we have not time to spare for 106 SULPHUR BURNING IN OXYGEN. all the illustrations you would have a right to if we had more time. We will take a piece of sulphur: you know how sulphur burns in the air; well, we put it into the oxygen, and you will see that whatever can burn in air can burn with a far greater intensity in oxygen, leading you to think that perhaps the atmosphere itself owes all its power of combustion to this gas. Fig. 24. The sulphur is now burning very quietly in the oxygen; but you cannot for a moment mistake the very high and increased action which takes place when it is so burnt, instead of being burnt merely in common air. I am now about to show you the combustion of another substance--phosphorus. I can do it better for you here than you can do it at home. This is a very combustible substance; PHOSPHORUS BURNING IN OXYGEN. 107 and if it be so combustible in air, what might you expect it would be in oxygen? I am about to show it to you not in its fullest intensity, for if I did so we should almost blow the apparatus up; I may even now crack the jar, though I do not want to break things carelessly. You see how it burns in the air. But what a glorious light it gives out when I introduce it into oxygen! Introducing the lighted phosphorus into the jar of oxygen. There you see the solid particles going off which cause that combustion to be so brilliantly luminous. Thus far we have tested this power of oxygen, and the high combustion it produces by means of other substances. We must now, for a little while longer, look at it as respects the hydrogen. You know, when we allowed the oxygen...
