A Kinetic Model of the Electron Atom. ole 
periodic variations of the properties of the atoms may be illustrated by 
the periodic variation of the number of needles in any of the rings, the 
inside ring, say. This has been done by Lyon. (Phys. Rev., Vol. 3, 
p. 232, 1914.) Figure 1 is a reproduction of the groupings of the needles 
taken from Mayer’s original article. The following table taken from 
Thomson’s work gives the theoretical groupings of the magnets from 
one to one hundred. The lower row of figures gives the number of 
magnets in the inside ring, and the upper row of figures gives the num- 
ber in the outside ring. The intervening rows give the number in the 
intervening rings.
