Studies of the polarizations of the micropulsation phenomenon, pearls, show a number of remarkable effects, in particular, reversals in sense of rotation. In this paper we consider the possibility that the superposition of a succession of signals having rising tones can produce the effects in question. It is shown that, if a number of signals of elliptical polarization all identical except for the inclination of the major axis and frequency are observed simultaneously, various effects, including apparent reversals in sense of rotation, will occur.
