So do platinum plates coated with oxygen and hydrogen 
respectively. I can now tell the amount of the force, and 
calculate how great a proportion of chemical affinity is used 
up electrolytically, before two such discs come within ToVoth 
of an inch of one another, or any less distance down to a limit 
within which molecular heterogeneousness becomes sensible. 
This of course will give a definite limit for the sizes of atoms, 
or rather, as I do not believe in atoms, for the dimensions of 
molecular structures.”
