16 We now have the equation

The summation of this gave a minimum value for : this, however, was considered only as a first approximation, and the process was repeated under pressure EAF, which gave to a partial maximum value: by continually increasing EAF, the result was at last obtained,  = S = 500.00000.

This result differs considerably from the anticipated value, namely 400.00000: still there can be no doubt that the process has been correctly performed, and that the learned world may be congratulated on the final settlement of this most difficult problem.
