IV. On some physical properties of argon and helium

Abstract

In our original paper are described determinations by Prof. Ramsay, of the density of argon prepared with the aid of magnesium. The volume actually weighed was 163 c. c., and the adopted mean result was 19·941, referred to O 2 = 16. At that time a satisfactory conclusion as to the density of argon prepared by the oxygen method of Cavendish had not been reached, although a preliminary result (19·7) obtained from a mixture of argon and oxygen went far to show that the densities of the gases prepared by the two methods were the same.
