* This number for sodic oxide agrees with Thomsen’s value for the 
hydrated oxide, whereas for K, Ba, Sr, Ca the oxide is distinctly below 
the hydrate. 
By analogy, one would expect to have to subtract some 
25,000 from the hydrated oxide Na,,O,aq., and this gives the 180,000 
which I put down as a hypothetical number for Na,,O.
