    Notes: [Auszug] MR. EVERSHED'S description in NATURE of December 22, p. 902, of a sound emanating from a thunder-cloud before the storm begins is new to me: I did not hear such a sound in Simla, nor have I come across a reference to this phenomenon in the large literature on thunderstorms. I see no reason to ...

    Notes: [Auszug] PROF. ARMSTRONG'S friendly criticism (NATURE, October 13, p. 537) of my theory of the origin of electricity in thunderstorms seems to neglect the fact that my explanation of thunderstorms is based entirely upon experimental and observational evidence. If experiments can be said to prove ...

    Notes: [Auszug] IF Sir Oliver Lodge will turn up his copy of NATURE for January 21, 1904 (Vol. 69, p. 270), he will find that I made there the identical suggestion for the origin of the earth's negative charge which he makes in NATURE of October 14, P. 512. The explanation is however, unsatisfactory for a ...

    Notes: Abstract: A new band, populated by the spontaneous fission of 248Cm and studied by means of prompt γ-ray spectroscopy using the EUROGAM2 array, was observed in 99Zr. The 1038.8 keV band head with a half-life T 1/2 = 54(10) ns is interpreted as a K-isomer, corresponding to the 9/2[404] neutron-hole excitation. It is the first observation of this orbital in the mass A ∼ 100 region. The quadrupole moment, Q 0 = 3.9(3) eb deduced for the new band indicates a large deformation of β = 0.41, which is produced by a specific shape-coexistence mechanism, known in other regions and now found in the A ∼ 100 nuclei.

    Notes: [Auszug] IN the preface to my book on Antarctic meteorology I wrote, “I was recalled to my work in India when the Terra Nova returned to the Antarctic in January, 1912,” and the reviewer in NATURE of December 23 (p. 528) has very naturally concluded that this meant that I was recalled officially by the ...

    Notes: Abstract The phase relations of divariant and trivariant assemblages involving combinations of phengite, chlorite, biotite, K-feldspar, quartz and H2O in the KFASH, KMASH and KFMASH systems were calculated using a single thermodynamic data set (Holland and Powell 1998). The stability fields of the various equilibria are represented in P-T projections by contouring sets of compositional isopleths for the Tschermak (Al2(Fe,Mg)−1Si−1) and FeMg−1 exchanges controlled by the coexisting phases. Five multivariant continuous equilibria, which occur in different regions of P-T-X space, are calibrated as thermobarometers in metamorphic rocks of pelitic to quartzofeldspathic composition. More subtle P-T information, relating to the trajectories (dT/dz) along which reacting rocks have been buried or exhumed, can be extracted from the continuous reactions by investigating the recorded compositional trends in the Al2(Fe,Mg)−1Si−1 and FeMg−1 solutions. Singularities in P-T space are associated with some of these reactions and may result in unusual mineral textures and compositional trends. A fluid-absent singularity has particular petrological significance because it marks the transition between hydration and dehydration along a single reaction with increasing pressure and temperature. This behaviour causes the sequence of reactions among these minerals observed during metamorphism to be critically dependent on the P-T trajectory. Thermobarometric calculations show good agreement with respect to experimental and field-based data for phengite compositions less than about 50 mol% celadonite (〈∼3.5 Si p.f.u. phengite).
