 EMI2.1 
 Grösse des Gefässes gepumpt wird. Die warmen Quecksilberdämpfe verbinden sich dann mit dem Sauerstoff, so dass annähernd reiner Stickstoff, übrigbleibt. Man kann zu diesem Zwecke auch Phosphor anwenden oder es wird ein solches Gas, welches vorteilhaft gegenüber dem Faden und Quecksilber indifferent ist, nachträglich eingeleitet.

 EMI2.1
 Size of the vessel is pumped. The warm mercury vapors then combine with the oxygen, leaving almost pure nitrogen. Phosphorus can also be used for this purpose, or a gas of this kind, which is advantageously indifferent to the thread and mercury, is subsequently introduced.
