On the modifications in hering's laws of furnace electrodes introduced by including variations in electric and thermal resistivity

At the meeting of the American Electrochemical Society in October 1909, a paper was read by Mr. Carl Hering on “Laws of Electrode Losses in Electric Furnaces”. At least seven interesting and important laws of electrode losses were enunciated and demonstrated in that paper, of which, however, only the two following need here be considered:
