    Notes: [Auszug] This led to an examination of the commercial sample of benzpyrene used in both these investigations, and it was found that this sample was, in fact, contaminated with tetrahydrobenzpyrene which was separated from it by chromatography on alumina from light petroleum solutions. The most easily eluted ...

    Notes: [Auszug] MR. WATT'S nil admirari attitude towards the C.G. of annual rainfall is unfortunate, for, notwithstanding his disclaimer in the first sentence, I find that his statement in the last sentence of his letter in NATURE of April 28 is another a priori shot ! In the Mysore rainfall annual reports of ...

    Notes: [Auszug] WE have reported that we were unable to obtain any evidence of œstrogenic activity in rats with benzylidenepyruvic acid and furylidenepyruvic acid or their sodium salts1. These negative results were attributed by Friedmann2 to the use of insufficient doses (100 ...

    Notes: [Auszug] IN view of the results published by E. Friedmann in NATURE of April 20, we decided to investigate the effect upon ovariectomised rats of the two compounds specifically mentioned by him as œstrogenic, namely, sodium benzylidenepyruvate and sodium furylidene-pyruvate. These were prepared and ...

    Notes: [Auszug] SUGGESTIONS have sometimes been made that the biological action of carcinogenic hydrocarbons is preceded by conversion, probably by oxidation, into water-soluble derivatives which may more readily be conceived as able to exert a direct action on the cells which eventually become malignant than ...

    Notes: [Auszug] BY the following simple arrangement a single pile of glass plates may serve at once as polariser and analyser, and be used to study or to exhibit on a screen the interference colours with mica or crystal sections. It may not be new, but I have not seen it given anywhere. A beam of light is ...

    Notes: [Auszug] We have found that 3 : 4-benztropolone is fungi -statically active ; at the highest concentration tested, specific fungicidal properties towards a few species were observed. The compound has weak bactericidal activity. We are indebted to Prof. H. Erdtman for a specimen of y-thujaplicin, which was ...

    Notes: [Auszug] WE wish to make the following comments on the communication by E. Friedmann in NATURE of April 20 (p. 622) under the above title:— (1) Dr. Friedmann apparently believes that the œstrogenic activity of synthetic compounds was first observed by Blum-Bergmann1, and afterwards ...

    Notes: [Auszug] THE mere a priori criticism which Mr. Watt, in his letter to NATURE of April 14, has bestowed on my letter to NATURE of March 31, dealing with a large class of concrete physical facts, is, to my mind, far from satisfactory or sufficient. In the last sentence of my letter I anticipated that it ...
