Inanother put a little charcoal (carbon),and in a third a piece of phosphorus*about the size of a pea. Let them standquietly and notice what changes, if any,take place. Sulphur, carbon, and phos-phorus are elements, and oxygen is anelement. It will be noticed that the sul-phur and the carbon remain unchanged,while some change is taking place inthe vessel containing the phosphorus,as is shown by the appearance of whitefumes. After some time the phosphorus will disappear entirely,the fumes will also disappear, and there will be nothing toshow us what has become of the phosphorus. If the temperatureof the room is rather high, it may happen that the
