✦ Synopsis

Terminal velocities and frequencies of oscillation are presented for single drops of an organic liquid falling through water. It is shown that no previous correlations of either the velocity or the frequency of oscillation are entirely satisfactory when the system is specially purified and when the drops are oscillating. Empirical correlations are presented for these variables.

The transition from a non oscillating drop to an oscillating drop was found to occur at a break in the plot of a modified Weber number, @dU,2DE/u), against a modified Ohnesorge number, (pa/ @duD,#*.

An empirical correlation is presented for the transition Ohnesorge number.
