AN ATOM A SMALL WORLD.

In a paper concerning the functions of the minute electrical charges in the chemical combination of atoms, delivered by Prof. William Albert Noyes of the University of Illinois, before the National academy at Washington, he said that for a century the atom was the ultima thule of smallness for scientists. Now they know that each atom is a complex system similar to our sun and its planets, that Is, with a central body and from one to a hundred smaller bodies revolving around it. The differences between hydrogen, oxygen, iron, gold, radium, etc., are all In the electrical charge of the central nucleus and in the number and arrangement of these little satellite* of their atoms.
