An accurate and simple method for the determination of the vapor pressures of solutions at low temperatures would be of great value to the physical chemist not only on account of the great theoretical importance of these figures but also because the method could be used to determine the molecular weight of any dissolved substance. The simplest method of determining the vapor pressure of a solution in the laboratory is the one suggested by Ostwald and worked out to some extent by Walker' and later by Will and Bredig.
