A Magnetic Float Method for Determining the Densities of Solutions

This is the authors' abstract. We don't add key points for this paper.

A method for determining the densities of liquids is described in which a float containing a magnet is utilized. The conditions under which the submerged float would remain poised are found by adding weights and by observing the effect of currents through a solenoid. The method may be adapted to the measurement of the densities of solutions at a series of increasing concentrations by forming the solutions directly in the vessel containing the float.
