The stream of hydrogen was allowed to bubble through C for some time to remove the last traces of air from the solution. It was then drawn up into the pipette and sealed off as before. When the solution was wanted its weight was, of course, not sufficient to draw it out; accordingly the following method was used to follow it up with hydrogen: A clean rubber tube, delivering a stream of pure hydrogen, was slipped over the drawn-out portion, and the tube was then broken; in opening the stopcock, the solution readily flowed Fig. 2. Rack with Pipettes containing Amalgams. The amalgams of indium and tin were prepared in the same apparatus. It was found more convenient to prepare the latter amalgams by adding the metals directly to the mercury in the atmosphere of carbon dioxide in the flask H, for they are far less readily oxidized than the others; but afterwards the amalgam was treated just as the Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Carnegie Institution of Washington.
