The bill itself contained no details on the type or amount of electricity that should be used and the New York Medico-Legal Society, an informal society composed of doctors and lawyers, was given the task of determining these factors. In September 1888, a committee was formed and recommended 3000 volts, although the type of electricity, direct current (DC) or alternating current (AC), was not determined, and since tests up to that point had been done on animals smaller than a human (dogs), some members were unsure that the lethality of AC had been conclusively proven.
