The low summation of Nos. 11 and 12 is due to inclosed or adherent sea salts. In No. 12 

 the amount of water-soluble matter was determined and proved to be 4.71 per cent, of which 

 0.55 per cent was SO3. Applying these corrections to the analysis the summation becomes 

 99.96. 



The reduced or rational analyses are as follows:
