13. The Density Observations .—In the case of the KOI solutions the densit} T 
observations were made in duplicate with a pair of pyknometers of the kind desci ibed 
in a former paper (Bousfield, ‘Trans. Chem. Soc.,’ vol. 93, 6/9, 1908). An accuiate 
series of densities for KOI solutions was given in a former paper (Boxjsfield, Zeit. 
fur Phys. Chem.,’ vol. 53, 312, 1905). For the purpose ot the present papei it was
