Abstract
VARIOUS authors1 have investigated the specific heat of Rochelle salt, the best-known example of substances showing spontaneous electric polarization, but the results obtained so far have been somewhat contradictory. In some of the experiments a small anomaly at the Curie point (the upper limit of the Rochelle electric temperature region) was observed. Very little is, however, known about any thermal effects at the lower limit of the Rochelle-electric region. This temperature has sometimes been called the ‘lower Curie point’, and it has been suggested2 that it should be marked by an anomaly in the specific heat.
