An apparatus has been designed following the method of Cioffi and Taylor (J. O. S. A. and R. S. T. 6, 906 (1922)), by which the resistance of 2 single crystal specimens can be determined simultaneously at temperatures ranging from liquid air to room temperature. The method is being used to investigate crystals of "spectroscopically pure" zinc.
