If therefore, we assume the atomic weight of boron to bea 
mean proportional between those of carbon and silicon, which we 
may do by an alteration certainly within the bounds of possible 
error in determinations so far made, we find that the proportion 
between the weights of carbon and boron, of boron and silicon, 
is the same as that between those of fluorine and chlorine.
