    miTcli superior to that from the softer. It may be added here, that animal charcoal, so useful as a decolorising agent, is very inferior as an absorbent. In my own experiments, the gases were collected by displacement in the usual way. By a simple arrangement, the amount of absorption was deter- mined by the quantity of mercury which flowed into, and was retained in the vessel containing the gas, into whicli the charcoal had been in- troduced. As the experiments have had a prac- tical aim, they differ in some respects from those conducted by the purely scientific chemists. The gases were not dried, since in the moist state they more closely resemble those of the alimentary cavities, and combinations of other substances with charcoal were tried in the hojje of discovering a still more effective absorbent than simple char- coal. The experiments have been veiy numerous, but it has not been thought desirable to encumber the table with more than seem necessary to eluci- date particular points ; and as the absorption of carbonic acid possesses by far the most interest, .this has alone been given. The absorbent action was instantaneous, and about seven-eighths of the whole was completed within two minutes. The time allowed for each experiment was an houi'
