TO THEIR STATE OF IONIZATION—MACGREGOR. 245 
THE DETERMINATION OF THE IONIZATION-CONSTANTS FOR ‘THE 
FREE IONS. 
The values of the constants L,, ,, Ls ete., may probably, in 
some cases at least, be aeecruinable in the following way: 
The experiments just referred to would give L+1, +l, ete., 
as well as Ka and sk, , ete. If now, guessing at the value of Ls 
we find the first three terms of (12) to be negligible at dilutions 
at which P., and P,, can be determined with sufficient accuracy, 
determination of these quantities will give the value of UM ap — tops 
and if a. and App be known with sufficient accuracy, ],,/,, and l, 
may then be found. It would of course be necessary to check our 
guess at the value of / by substituting the value found in 
expression (12) and seeing whether or not with this value the 
first three terms would be negligible.
