the generalization that the properties of the chemical elements tend to be regular functions of the atomic wieghts. “To put it differently, if the elements tend to be grouped in the order of their particular atomic loads, it should be found that almost the exact same properties recur occasionally for the whole show.” Here tabular arrangement of atomic loads reveals the normal recurrence of teams (under I., II., III., IV., etc.), each consisting of members of the same normal family. The spaces inside table indicate the possible presence of not known elements.
