Measurements made of the charges acquired by water drops and smooth ice spheres suspended in electric fields and exposed to streams of positive ions only, negative ions only, and ions of both signs present in equal and unequal concentrations were found to be in excellent quantitative agreement with the equations of Whipple and Chalmers. Electrical masking was probably responsible for the slightly increased charging obtained when the experiments were repeated with ice spheres of irregular surface structure. The charges acquired by drops falling through ion streams in electric fields are explicable in terms of the Wilson process.
