    Notizen: [Auszug] THE appearance of the letter in NATURE of Sept. 13, by J. C. Drummond and E. R. Gunther, on the vitamin content of marine plankton, simultaneously with the résumé on p. 423 of the same issue, of the paper by G. Belloc, R. Fabre, and H. Simonnet on the study of plankton sterols, stresses the ...

    Notizen: [Auszug] IN view of the fact that a study of the literature on the red and brown algæ revealed considerable uncertainty as to whether true cellulose occurs in these plants, the following seaweeds were examined for cellulose by the usually accepted methods :— among the red algæ, Corallina officinalis, ...

    Notizen: [Auszug] INVESTIGATORS of metallic systems by thermal and X-ray methods have found many binary intermetallic compounds ; they have found, however, only a few ternary and no quaternary compounds. If a metal or metals of one class (zinc, tin, cadmium, mercury) reacts in mercury at ordinary temperature ...

    Notizen: [Auszug] INVESTIGATIONS recently carried out in this department on the marine algæ have shown that there would appear to be some connexion between the depth of immersion of such weeds and their metabolism, as expressed by their chemical composition. Such connexion has been traced in regard to their ...

    Notizen: [Auszug] IN 1905, Wilfarth, Römer, and Wimmer published in the Landw. Versuchs. Stat., vol. 63, a paper, “Über die Nährstoffaufnahme der Pflanzen in verschiedenen Zeiten ihres Wachstums”. The importance of this paper in agricultural science was soon recognised, and before long an English translation was ...

    Notizen: [Auszug] MR. F. S. RUSSELL1 is certainly correct in assuming that the occurrence of tunny (Thunnus thynnus L.) in the North Sea is not of recent date. The Fisheries staff, during their investigation of herring trawling in 1912 and 1913, frequently observed this magnificent fish in ...

    Notizen: [Auszug] ZANSTRAS recent determination of the temperatures of the O-stars in planetary nebulæ1 makes it appear extremely likely that these stars are all generically in the ‘white dwarf’ class, with mean densities far above anything known on the earth. He has found temperatures between ...

    Notizen: [Auszug] ATTENTION has not previously been directed to the possibility of formation of intermetallic compounds (other than with mercury) in liquid mercury. It is expected a priori that if such compounds are formed they would be unstable. With Mr. P. V. F. Cazalet I am investigating this problem and our ...

    Notizen: [Auszug] ACCORDING to Nernst's theory of electrode potentials, a very small concentration of a reactive metal should be deposited on a noble metal when the ions of the former are brought in contact with the latter. The effect is usually regarded as being too small for demonstration. Dr. G. von Hevesy ...

    Notizen: [Auszug] IT may not perhaps be generally realised that the common cuttlefish, Sepia officinalis, uses its siphon for slow swimming in all directions, as well as for the more violent backward leaps. We recently had an opportunity of watching the behaviour of cuttlefish which were swimming at eye level ...
