Essay by v. Weymarn “On the Doctrine of the States of Matter” represents the first chapter of his conceived and partially already completed work on the structure of matter based on the data obtained by studying the so-called "colloidal" state of bodies. Weimarn's discovery of a universal method for obtaining all kinds of crystalline substances (crystalloids) in the so-called colloidal and amorphous states led him to propose that both states are inherent in all bodies and depend only on the degree of fragmentation of the substance, and therefore, on the relative development of the surface, and that, furthermore, there is no other difference between the crystalloid and colloidal-amorphous state of a body, and to attempt revise our ideas about the nature of matter, based on the above principles.

The law of Matthiessen and Vogt makes it possible to bring together two classes of alloys. Both represent mixtures, the former are substances that correspond in their properties to the temperature of observation, the latter are substances that appear to have been heated to a higher temperature, and therefore possess somewhat different properties, yet these properties can be predicted, since this fictitious higher temperature determines the meaning and magnitude of the changes they may have undergone. This can be confirmed to a certain extent by the effect of annealing on the electrical conductivity of alloys, for example, the thoroughly studied pair of silver and copper. Before annealing, alloys exhibit greater resistance, being initially in the hardened state.
