Abstract
BY 305 hours of repeated fractional vaporisation from a steel trough in a vacuum at low pressures we have obtained a difference of 0.1 unit in the atomic weight of mercury without other cooling than that given by ice. The trough holds 190 c.c. of mercury, but another larger apparatus has been constructed in which the capacity is 10 kilos. In this the mercury is heated by an insulated wire which lies in the bottom of the trough, the insulation being obtained by a coating of magnesium oxide, which is covered with a steel sheath. This wire is produced by the General Electric Company.
