THE annual report of the Indian Association for the Cultivation of Science for the year 1941 includes the report of the committee of management and a list of papers published in the Indian Journal of Science, vols. 14 and 15, together with a report by Prof. K. S. Krishnan on the scientific work of the Association. This includes an account of magnetic studies on gadolinium sulphate octahydrate and of the spin-orbit coupling in cobaltous ions deduced from the magnetic properties of blue cobalt salts, in which results were obtained strongly supporting the theoretical prediction that there should be an inversion of the Stark pattern, first in a given cubic field as we pass from cobaltous to nickelous ions, and second for either of these ions as the disposition on the negative ions surrounding them changes from a tetrahedral distribution to an octahedral one. Reference is also made to magnetic measurements on a large number of cupric Tutton salts at low temperatures, in which also the cuprous ions possess practically the same type of anisotropy as in copper sulphate pentahydrate. The paramagnetic properties of several other salts of the iron group have been studied at low temperatures, and reference is made to the results obtained with some of the ocomplex salts such as potassium ferricyanide. Preliminary measurements on the magnetic properties of mobile electrons in condensed ring hydrocarbons such as anthracene, chrysene, pyrene, etc., indicate that there is a decrease of the order of a few percent oof the diamagnetism of the mobile electrons as we pass from room temperature to about 300o. The metallic nature of the mobile electrons in aromatic molecules is supported by the observation that the absorption bands in the violet and in the near ultraviolet regions in anthracene crystals, presumably due to the mobile electrons, are paralleled by the strikingly selective refraction of the crystals in the region of these absorption bands, those wave-lengths that are strongly absorbed by the crystal being those that are strongly reflected from its surface. Measurements on the polarization of fluorescence of anthracene, phen-anthrene, chrysene, and naphthacene in highly viscous solutions lead to the conclusion that the fluorescence is due either to a single linear oscillator or to a set of linear oscillators that radiate independently.
