Abstract

There are many interesting formations which may be prepared in gels. Probably the best known are Liesegang rings, first prepared in the latter nineteenth century and observed previously in such naturally occurring materials as agate. Besides rings periodic radial structures have been observed in gelatin. Some of these radial formations are visible to the naked eye; others may be observed only under a microscope. It is one of the radial formations of the layer type which will be discussed in this paper. For want of a better name the formation to be discussed will simply be referred to as radial lines. These lines are prepared by diffusing silver ion into chromated gelatin while mercury vapor is present. In this paper a short summation of the work done by previous investigators as well as experimental work done by the author will be presented.
