This table brings out the remarkable fact that the paral- 

 lelism between the dynic and refraction-equivalents is so 

 close as almost to amount to proportionality. I shall not 

 discuss the meaning of this relation until I have shown how 

 to obtain the dynic equivalents for the elements usually 

 occurring in inorganic compounds, and established the same 

 relation for them also. 



Meanwhile it will be useful to compare the dynic and 

 refraction equivalents of the uncombined elements and of 

 those simpler typical compounds to which we have said the 

 summative law does not apply as regards dynic equivalents and 

 does not accurately apply as regards refraction-equivalents.
