Abstract

WITH reference to the letter by Ny Tsi-Zé and Tsien Ling-Chao published in NATURE of August 11, 1934 (p. 214), it is interesting to note that annular quartz rings cut in a plane perpendicular to the optic axis were investigated by Giebe and Scheibe1 in 1928, by the luminous resonator method. Such a ring, oscillating in its fundamental longitudinal mode, was also made by Dye, and was afterwards developed to form the primary standard of frequency at the National Physical Laboratory. More recently, similar rings oscillating in an overtone longitudinal mode have been investigated in an attempt to incorporate the most successful features of the different types of quartz oscillators which have been developed to form frequency standards in this and other countries.
