(iii.) Conversion of Chlorate to Chloride. — The latest experimental ratio 
of KCIO3/KCI is 1-643819. Assume that KCIO3 is— 
{i.e.., that chlorine is always monovalent), and that — 
K=: 39-100 H, 
and — 
Then— 
This gives — 
CI = 35-500 H.

Generally speaking, the author is inclined to think that the tetra- 
valency of oxygen should play a large part in chemical theory, and should 
be used to explain the so-called "higher valencies" of most of the 
elements.
