    Notes: [Auszug] SINCE reading the interesting accounts of this phenomenon by Prof. W. Schmidt1 and Prof. H. Stansfield2, I have noticed several striking instances which yield a clue to their cause. They occurred on the surfaces of clear country streams bridged by planks that ...

    Notes: [Auszug] THE authorities on cooking understand the effects of time and temperature1 better than one might be led to suppose from Mr. Dufton's comments in his letter2 under the above title. The new technique is interesting, and has some obvious advantages over normal ...

    Notes: [Auszug] UNDER the above title Mr. H. J. Woods1 proposes three alternatives to the ‘weathering’ hypothesis tentatively advanced by me2 to account for supernormal curvature in the apical region of certain guard hairs. Of the opposing evidence, it will suffice to point out ...

    Notes: Abstract The settling rates of the larvae of the blackfly Simulium damnosum Theobald, were monitored at a Simulium breeding site on the Bandama River in the Ivory Coast. Significantly greater numbers of larvae were found to settle during the night than during the day, and there was a significant increase in the settling rate immediately following the onset of darkness. The drifting larval population contained significantly greater numbers of smaller larvae than the general population.

    Notes: The electrical resistivity and specific heat of samples of 241Am and 243Am are reported. The electrical resistivity at room temperature is reduced compared with the value for plutonium, while the power law exponent at low temperatures is increased. The electronic specific heat coefficient is lower than for the lighter actinides. These features lead to the conclusion that americium is the first of the actinides in which the 5 f electrons are essentially localized. Anomalies occur in the electrical resistivity and in the specific heat in the region of 60 K, the cause of which is unknown.

    Notes: Abstract The thermal conductivity of α-plutonium has been measured over the range 3–100 K. For the highest purity material (∼50 ppm metallic impurities) a small peak in the conductivity is seen at ∼10 K, followed by a shallow minimum at 40 K. The maximum measured conductivity is 34.3 mW/K cm at 100 K. A decrease in conductivity occurs at low temperatures as a result of radioactive self-damage, which saturates with an exponential dependence. It is shown that most of the heat conduction is by phonons, electronic thermal conduction being small but rising with temperature.

    Notes: Abstract The electrical resistivity of protactinium metal has been measured between 0.90 and 300 K. The absolute value of the resistivity is between that of thorium and uranium, with ρ 298 =19.28 µ Ω-cm. A change in slope of the resistivity was observed at 103 K and remains unexplained. No superconductivity was observed down to 0.9 K. The resistivity ratio ρ 273 /ρ o was 9.27, showing the sample to be reasonably pure.

    Notes: Abstract The specific heat of polycrystalline α-uranium has been measured between 4.2 and 80 K. In addition to the second-order transition at 43 K, always seen in both polycrystalline and single-crystal uranium, a small effect was observed at 22 K. This had previously been seen only in single crystals. The larger, first-order change seen at 37 K in single-crystal uranium was not observed. The possible explanations for this difference are discussed.
