• (1) Our results show that the form of the hysteresis loop is dependent on the velocity of the variation of field (the frequency), and the loop becomes thinner as the velocity is decreased, but it never collapses entirely. The coercive force is therefore not a sharply defined constant. The dielectric after-effect is especially large in weak fields. (2) A real crystal of Rochelle salt always possesses a non-vanishing polarization in virgine state, that is, when it is cooled down from above the Curie point in the absence of field. This spontaneous polarization is quite stable against external field (direct and alternating) and has always the same sense each time it is cooled from above the Curie point. (3) The Curie point, defined as the temperature of the vanishment of spontaneous polarization, is not a sharply defined point located at 23℃, but is distributed rather broadly between about 20℃. and 28℃. In conclusion, we wish to express our hearty thanks to Dr. H. Kawai of the Kobayasi Institute of Physical Research, who was always ready to give us the samples, as well as helpful technical advices.
