ResumoAlthough the electrolysis of brine is an old process, information in regard to it is scattered and hidden in the records and patent litcrature of industrial concerns.Dakin and Carlisle1 have pointed out its convenience and economy in preparing dilute sodium hypochlorite solutions for disinfection purposes and have designed a simple cell.In instlvcting army surgeons in the various methods of preparing Dakin's solution, it was desirable for us to determine for ourselves the factors that were of practical importance in its electrolytic preparation.These results are presented for the convenience of other workers. EXPERIMENTAL.Choice of Cell.-It seemed desirable to use a cell that could be connected with ordinary 110 volt current, that did not require unusually heavy wiring or power, that was light and strong enough to be transportable with ot,her niilitary hospital equipment, and that was inexpensive.The cell described by Dakin and Carlisle ansivers these requirements, but we were spared the labor of making'this cell by modifying cells already ,on the market to our purpose.These cells are entirely similar to that described by Dakin and Carlisle, except that the electrode area is smaller in proportion to the volume of solution.The twenty-three intermediate elec-
