TO LESSEN THE EFFECTS OF ELECTROLYSIS.

By periodically reversing the current the evil effects of electrolysis, according to A. Larsen, of the Copenhagen Technical college, who has been experimenting on the subject, may be lessened. He buried several lengths of pipe, six to four-inch, with their ends separated; through these equal currents were passed. The direction of the current, 0.121 to 0.341 amperes, was maintained uniform in some; in others it was reversed every hour; in others every twenty-four hours. The pipe was then weighed, and it was found that, with twenty-four hours’ reversal of current, the loss in weight was only one-fourth that of those in which the current was maintained constant. In that case the loss was thirty times as great as when it was reversed hourly.
