The force thus originating I designate as the molecular force 
of heat-repulsion ; but it should not be confounded with the 
heat energy in the body, derived from extraneous sources, or 
ward, through the interstitial electric ether, a series of repul 
sive waves. These may be represented by a resultant wave 
system, which must obviously be regarded as proceeding from 
a center nearer the outer then the inner surface of the er 
velope, as at m, fig. 3. This resultant system of repulsive 
waves, as it originates in the electric envelope, and is propa 
gated by the interstitial electric ether, is termed the molec 
force of electric repulsion. 
The result then is, that the molecular forces consist of one attrac. 
tion and two repulsions; all originating in the primary force of 
repulsion. They are made up of impulses propagated in waves; 
and hence must observe the law of the inverse ratio of 
square of the distance. : 
rom these fundamental results I have deduced in my pen 
paper on Molecular Physics, the following general analytica 
expression for the intensity of the effective action of one Pi 
mitive molecule on another, in terms of the distance, 2, betwee? 
the envelopes of the two molecules ;
