Let the arrangement rest for a short time for the fumesof phosphoric anhydride to subside and dissolve in the water,and then decant the gas into test-tubes in the manner indi-cated in Fig. 9, using a tub or other vessel of water of suffi-cient depth to permit the glass containing the nitrogen to beturned on one side without air gaining access. Larger quantities of nitrogen are made in the same way. Othercombustibles, such as sulphur or a candle, might be used to burn outthe oxygen from a given quantity of air, but none answer so quicklyand completely as phosphorus ; added to which, the produ
