Abstract
The above arbitrary division is due to the fact that the experimental work does not include an examination of the vapour phases. Experimental. The solubility determinations were carried out in thermostats of an ordinary pattern. Glass bottles similar to those used by van’t Hoff (‘Ozeanische Salzablagerungen,’ p. 9) were used for solutions weak in sodium hydrate. Silver bottles, as shown in fig. 1, were used for the strong sodium hydrate solutions.
