The solidified gases in the condenser H were allowed to evaporate into thereservoir in which was stored the gas obtained from the five delivery tubes,the last traces of gas being swept out with carbon dioxide. The combinedgases in the reservoir were then worked up in the usual manner by passingthem over soda-lime, metallic copper, magnesium-lime mixture, and copper•oxide. The resulting gas was stored over mercury. On running it into abulb immersed in liquid air, it solidified at once, but was not fractionatedseparately, being transferred back to the mercury reservoir through the volume was about 50 The gas remaining in the large flask F (fig. 3), and in the small tube G-«(fig. 4), together with that in the wine bottles which contained the gas. Fig. 3. -transferred from four of the other flasks shown in fig. 3, was purified in theusual manner with magnesium-lime mixture, etc. The inactive gas wasmixed with the 50 already obtained and stored over mercury. The total volume of water and caustic soda solution which had been in con-tact with the gas at any period was not more than 20 litres. All of this was > carefully kept and thoroughly boiled, the evolved gases being worked up in VOL. LXXXI.—A. P 206 Prof. R. B. Moore. An Investigation of the [June 23,;philtrans09174850
