    Notes: [Auszug] A FEW years ago Mr. Geo. L. Harrington, of Buenos Aires, was prospecting in the Santa Barbara district of the Province of Jujuy, Argentina. In this region we find deep gulches with good exposures of the geological formations. A very conspicuous and important formation consists of green rock, ...

    Notes: [Auszug] MINCHIN, in his well-known volume, “An Introduction to the Study of the Protozoa”, 1912, states that the species of the genus Opalina differ in certain peculiarities of structure and life history from all other ciliates. The life history has been studied by Metcalf and Neresheimer, whose ...

    Formation of the Spore Tails in Haplosporidium chitonis (1925)

    Topics: Biology , Chemistry and Pharmacology , Medicine , Natural Sciences in General , Physics
    Notes: [Auszug] IN Haplosporidium chitonis the method of formation of the spore tails, which grow to a great length after the completion of the spore coat, has always been rather difficult to understand; it seemed unlikely that the material for these tails could be provided from the interior of the spore, ...

    ISSN: 1476-4687

    Topics: Biology , Chemistry and Pharmacology , Medicine , Natural Sciences in General , Physics
    Notes: [Auszug] I WAS much interested in Mr. Cowper's letter in NATURE of February 21 on radio reception on frame aerials. For some time I have been quite sure that the usual estimates of probable signal strengths are much too low. On a four-valve (i H.F. Det. 2 L.F.) it is possible, on a roughly ...

    Notes: [Auszug] MAY I express my interest in your recent correspondence on quartz spiral springs (NATURE, June 20, p. 943, and July 4, p. 14), and suggest a convenient laboratory method for the production of springs of extreme sensitivity. I refer to the use of fibres the diameter of which is ...

    The Effective Wave-length of γ Rays (1925)

    Topics: Biology , Chemistry and Pharmacology , Medicine , Natural Sciences in General , Physics
    Notes: [Auszug] IN his letter to NATURE (January 3, 1925, p. 13), Prof. Gray states: “If the secondary β-rays, produced in light elements by the hard γ-rays of radium-C, are recoil electrons, with energy given by the quantum theory of scattering, … the effective wave-length of the γ-rays must be much smaller ...

    ISSN: 1476-4687
    Source: Nature Archives 1869 - 2009
    Topics: Biology , Chemistry and Pharmacology , Medicine , Natural Sciences in General , Physics
    Notes: [Auszug] IT is reasonable that the unexpected results of the recent repetition of the Michelson experiment by Prof. D. C. Miller should have made Dr. Silber stein say that they “knock out the relativity theory radically” (NATURE, May 23, p. 798). But though Einstein has built the special Theory of ...

    Topics: Biology , Chemistry and Pharmacology , Medicine , Natural Sciences in General , Physics
    Notes: [Auszug] THE most accurate determinations of the atomic weight of chlorine indicate that on earth this element consists of 76.65 per cent. of chlorine of isotopic number 1 (atomic weight = 35) and of 23.35 per cent. of isotopic number 3 (atomic weight = 37). It is of interest to ...

    Notes: [Auszug] MR. A. J. LAVRUSHIN, a keen student of geology, who was my interpreter in Siberia, has sent me a careful drawing of a fossil insect which he received from a teacher in the Commercial School at Harbin. It was obtained near the coal mines at Soochan, in the Maritime Province of Siberia. The ...

    Notes: [Auszug] THE question raised by Mr. Banerji is certainly important from the point of view of exact astronomy, but it is not new. It was fully discussed several years ago, and at Rome in 1922 the geodesists stated that field operations with small instruments in the open did not show anything like the ...
