211. The following is a list of the cells examined in which 
the value of k;—f, is of the opposite sign to, but not greater 
in magnitude than, Eq; so thatthe E.M.F. actually set up is 
less in numerical value than that predicable from the relative 
heats of formation of the electrolytes ; only those cells are
