The results are recorded'in three columns. In Column A the solubility in 
milligramme molecules per litre is given; in Column B the solubility in 
grammes per litre of solvent; and in Column C the relative solubilities, that 
in water being taken as 100.

In the above table the salts are divided into five subdivisions, viz., the 
inorganic monobasic salts, or salts of low viscosity, sodium formate, a salt 
with viscosity between those of the inorganic salts and the other organic 
salts, the organic monobasic salts with high viscosities, the salts of polybasic 
acids, and salts of metals other than sodium. The monobasic sodium salts 
are placed in descending order of their surface tension in the columns. 
This arrangement indicates at a glance the generalisations arrived at in the 
theoretical introduction to the three papers.
