The new phenomenon of large scale domain structure in evaporated thin films of glassy chalcogenide alloys has been studied extensively by transmission electron microscopy. Non-coalescing polygonal domains with average diameters as large as 1000 A are

The distribution of cells in a planar section of a soap foam is determined at different stages of growth, and the shape of their sections is related quantitatively to that of the adjoining cell sections by an empirical equation. This observed regular

The grains of a polycrystal are found not to be disposed at random, but to be arranged in a way that can be quantitatively expressed in simple terms. The arrangement is shown to account for the observed, well-defined stages of grain growth, and an at

The stability and distribution of grains in a polycrystal indicate that their surface behaves like that of an isolated crystal.

The shape, distribution, arrangement, and stability of cells in a typical foam and polycrystal are compared, and their observed dissimilarity is attributed to a fundamental difference in the structure of the two systems. In particular, it is shown th

Grain diameters in porous and nonporous magnesium oxide are shown to be distributed in the same way as in a metal. The spread of the distribution appears to be influenced by the purity of the ceramic, but not by the average grain size.

The distribution of the shape of grains in a fully annealed polycrystal is found to resemble that of their size, and to be governed by similar laws.
