X-ray measurements have been made of changes in the lattice spacings of Rochelle salt between —90 and +40° C. Rough visual estimates have also been made of changes in the intensities of X-ray reflexions with temperature. The thermal properties of

Considerable frequency dispersion of electrical conductivity has been observed in the liquid crystal phases of organic ionic melts, depending on their molecular structure and domain size. Dispersion began to be detectable above about 10000 Hz for s

A simple but sensitive horizon test is described to determine whether the mesophases of molten organic salts exhibit any detectable elastic-plastic threshold, before they begin to flow under even very small applied shear stresses. By using this test

An improved method for making measurements normal to the layers in lamellar compounds is described. This preserves good contact under moderate pressures, while permitting unobstructed expansion of the specimen during intercalation, or changes of temp

The interleaved texture of human growth can sometimes be followed back to more than one kind of early experience, and often stems from more than one genetic element. Subtle and continuous elements affecting the life of Dudley Newitt came from his you

Various physical properties of alkali carboxylates can be used to study precursor effects immediately below or above their melting points. The present paper describes unusual pre-transition behaviour observed in the magnetic susceptibility of molten

X-Ray measurements have been made on single crystals of caesium chloride from 20 to 469° C 495° C traversing the transition CsCl (b. c. c.) ⇌ 469°C CsCl (f. c. c.). Contrary to previously published statements which were all based on CsCl powder,

Hydrogen electrolyzed into palladium changes the internal friction. In torsional oscillations at 0$\cdot $54 and 0$\cdot $22 c/s an immediate large increase of internal friction is observed after charging, or after removing some of the hydrogen by el

Observations are recorded on X-ray spectra diffracted from cathodes of iron and palladium during actual discharge and diffusion of hydrogen. For iron, no expansion of the crystal lattice greater than 0$\cdot $0002 angstrom could be observed during su
