    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 ...

    Topics: Biology , Chemistry and Pharmacology , Medicine , Natural Sciences in General , Physics
    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] THE chemical constitutions of ketohydroxycestrin and trihydroxyoestrin are now largely established, mainly by the investigations of Butenandt, Marrian, and their collaborators. There remain, however, certain features of the molecular structure which have not yet been experimentally proved, but ...

    Notes: [Auszug] A SEQUEL to the formulation of the sterols and bile acids as hydrogenated phenanthrene derivatives1 was the suggestion2 that carcinogenic derivatives of 1:2-benzanthracene might arise by abnormal sterol metabolism. No experimental evidence for ringclosure to the ...

    Notes: [Auszug] THE nature of the cancer-producing constituent (or constituents) of coal tar has been under investigation in this and other laboratories for some years past, but hitherto no known constituent of tar has been found to have definite cancer-producing properties, and no new carcinogenic constituent ...

    Notes: [Auszug] IN conformity with the hypothesis, for which there is at present no experimental basis, that the ovarian hormones are formed by degradation of sterols, and in the light of recent developments in the chemistry of the sterols, ketohydroxy-oestrin is possibly represented by formula (i).

    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 ...

    Notes: [Auszug] THE ordinary method of exhibiting the annual distribution of rainfall for any station or country is a graph the ordinates of which represent the monthly rainfall. Though this pictorial method is both useful and interesting, it does not lend itself to the ready comparison of a number of such ...
