        • Abstract: Volume IV/1 contains information on the densities of liquid systems. It may be considered as a supplement to volume II/1 of the 6th Edition, which contains only a few data on nonaqueous systems. Data are not listed for all systems but primarily for those of greater interest where data for a larger range of concentrations were available.
