Crystals of the cubic system
Abstract
In this article, I present, as complete a list as possible of crystals of the cubic system obtained to date. Here we are indeed dealing with a series of substances exceptional in their properties, as the forms of the cubic system are exceptional among all others. Once the list is compiled, this exceptionality in the chemical composition of the substances is striking, if only the possibility of dividing them into the few categories that form the basis of my exposition. Other features of the chemical composition of substances in this series will be discussed at the end of the article. It was necessary for me to compile this list already for the purpose of singling out,from among those described, the crystals that are not amenable to determination by the method of crystal-chemical analysis.
