✦ Synopsis

Evaporation of Quicksilver in a Vacuum.--H. Hertz has made some investigations of the evaporation of liquids, especially mercury, in a vacuum. The chief interest of his results is connected with the pressure of the vaper at the ordinary temperature of the air. AccoMing to his experiments, the pressure amounts to less than a thousandth of a millimetre (one-twenty-five thousandth of an inch). The insignificance of this pressure, rather than any special peculiarity of tile qui&silver itself', must be the reason for the imperceptible influence which the quicksilver vapor, in Geissler tubes, produces upon the discharges.--Wied. Ann, No. 10, 1882.
