??????? A few years ago physical science assumed that an atom was the smallest imaginable part of a given element of matter; that although infinitesimally small, it still represented solid matter. Now, in the light of better evidence, we have good reason tobelieve that there is no such thing as solid matter: that every atom is made up of charges of negative and positive electricity acting in and upon an omnipresent ether; that the difference between an atom of iron and of hydrogen or any other element consists solely in the number of electrical charges or corpuscles it contains, and on the velocity with which these vibrate around one another.
