Página 2 - The amounts of different substances deposited or dissolved by the same quantity of electricity are proportional to their chemical equivalent weights.
Página 77 - ... also chemically, symmetrical, are obliged to orient their bodies in a certain way in relation to certain centers of force, as, for instance, the course of light, an electric current, the center of gravity of the earth, or chemical substances. This orientation is automatically regulated according to the law of mass action.^. The application of the law of mass action to this set of reactions is thus made possible. I consider it unnecessary to give up the term "comparative psychology...
