Compiler speculates that the experimental values were, in all likelihood, determined by a gravimetric method, which was common practice during this era. The method probably involved equilibrating excess solute and solvent in sealed containers, transfer of weighed aliquots of saturated solution to tared containers, evaporation of solvent, and weighing of solid residue that remained.
