The contrast between this electrolytic order, and that of atomic weight, is very conspicuous. Hydrogen and gold, the lightest and heaviest atoms, meet here in the middle of the list. Chlorine 36 and potassium 39, fluorine 19 and calcium 20, which are very near in atomic weight, are found at or near the two extremes. On the present theory the atomic numbers must depend on the relative number of monads which compose each atom, and the electric order on their radial or axial arrangement. For the positive pole of the electric current must be conceived to represent a superior velocity of atomic rotation, or greater vis viva, and the elements which tend to that pole or electrode must be those which have the greater moment of rotation, or a less axial and more radial structure. Hydrogen, of the simple monads, must be neutral in this respect, or claim a middle position. The regular metals must be supposed, from their cohesion, to be slightly or strongly polar; and the precious metals which are least oxydizable, to come near to hydrogen with regard to equality of moments, which is indicated also in mercury by its great fluidity. Atoms of nearly equal weight, if they come near the extremes, may be expected to have contrasted properties, but when they come near in the series, to have a close resemblance. Thus cobalt and nickel, which are near iron in both respects, are also magnetic and hard metals. But chlorine and potassium, fluorine and calcium, ..
