214 On the Determination of Chemical Affinity. 
212. The following is a list of the cells examined in which 
the value of k,—k, 13 not numerically greater than Hy, and 
lies witbin the limits +0°l volt. Itis evident that the number 
of cells coming into this category is only a fraction of the 
total number of combinations examined.
