The evolution of etch phenomena on (111) natural octahedron faces of a number of good-quality diamonds, produced by immersion in hot potassium nitrate in temperatures ranging from 500 to 700° C, is studied optically. The techniques employed are high

The study of pressure figures on diamond is extended to the cubic and dodecahedral faces. The formation of cracks on a sawn but unpolished dodecahedral (two-point) face is first studied. The loads required for the initiation of cracks, using a diamon

Precision multiple-beam interference methods are applied to the study of the topography of octahedral faces of three diamonds. A new crossed fringe technique of high sensitivity is described. Evidence is adduced to support the view that the curvature

Stratigraphical etch patterns obtained on diamond surfaces are shown to reveal structure within the diamond. A study has been made of the complex structure of an octahedral diamond by examining eleven successive polished cubic sections. This exposes

The first detailed examination of the fine structures occurring in the visible lines of the Sb II spectrum was made by Badami, who reported extensive structures in many lines. Badami attempted to excite the Sb II spectrum in a hollow cathode discharg

The etch patterns formed on octahedral cleavages of diamond are studied optically. It is established that etch pits are distributed in three ways ( a ) random small pits, ( b ) striking linear arrangements, ( c ) individual isolated pits usually larg

An account is given of optical and interferometric studies on spiral patterns which have been found on the basal planes of synthetic quartz crystals. These patterns have high visibility and show both single and interlaced triangular spirals, of but a

In an earlier paper by Tolansky (1935 a ) measurements were given for the fine structures of forty-two lines in the visible region of the first spark spectrum of iodine. Of these eleven had then been classified by Murakawa (1933). It was proved that

The platinum isotope 195 has an odd atomic weight and an even atomic number, that is the nucleus contains an odd neutron. It has been shown elsewhere by one of us that the distribution of nuclear spins in the nuclei with an odd neutron is totally dif
