Abstract
A NEW and very promising scientific journal—Science Reports of the Tôhoku Imperial University, Sendai, Japan, vol 1, No. 1—printed in English at Tokio, has recently been issued (June, 1921). It contains the results of an investigation, commenced at Cambridge, by Mr. S. Kozu, who was assisted later in Japan by Y. Endo and M. Suzuki, on the X-ray analysis of adularia felspar from the St. Gotthard and the moonstone of Ceylon and Korea, and on the influence of temperature on their atomic arrangements. Adularia and moonstone are supposed by mineralogists to be solid solutions of varying proof the monoclinic felspars by Mr. Kozu, the results of which were communicated to the Mineralogical Society in 1916, showed that these constants are much higher for moonstone than for adularia. This is due to different molecular structure corresponding to a different chemical composition, the optical constants always increasing with the presence of soda, of which moonstone contains nearly three times as much as adularia.
