Results: To date, work on four electrolyte salts have 
been completed. These are NaCl, KC1, MgSO, and Na 7SOq.

results obtained. In the tables, at each concentration 
(salinity) and each temperature, the first row gives values 
of saturation heat capacities, while the second row gives 
constant pressure heat capacities. In addition, along with 
each table some polynomial equations obtained from the 
curve fitting are given for both sets of values. The 
concentration, S (/oo.(salinity) is defined as grams of
