The specific heat of 7 alloys in α-solid solution range of copper and zinc system has been measured in an annealed and a quenched state by an inverse rate curve method. The specific heat-temperature curves of the annealed alloys generally show an anomaly at about 200° to 260°; the anomaly is most conspicuous in alloy containing 30.35 percent of zinc. And, while the temperatures of the knicks on the curves of alloys containing less than 20.75 percent of zinc are almost the same, they become lower when the content of zinc is increased to more than 20.75 percent. This anomaly can be prevented by quenching from 500゜. Thus, it has been concluded that the anomaly may be caused by the existence of the superlattice Cu_3Zn in a short range order and not by the change of the solubility of α-solid solution.
