Prof. W. ]. Herdman has now completed his scientific research as to the result of electricity upon the growth of animáis He has satisfied himself beyond any doubt that aniraals subiected to an electrical field can be made to grow more rapidly than the same animáis when not surronnded Ly the influences of an electrical atmosphere. Some of the time the animáis used in his experiments were rabbits and at other times guinea pigs. As soon as the animáis were old enough to be separated f rom their mo:her,they weiedivided into bunches as nearly alike in age and weight as possible. The two bunches were placed in conditions of living in all respects similar except that one bunch was treated in a rage through which an alternating electric current passed for a period of six hours each day. When the time expired for the animal? to get their full growth, it was found that the "electrically" treated animáis had gained from 18 to 24 :er cent at the end of each succeedng'week. This has been the stimulating efect and Prof. Herdman has deduced the averages to show thet the imit of the time of treatment, or daily application s hould be about two hours. He has lately beer. investigating the depressing effect by applying a stronger and more lasting current and the results he is obtainins are just as interesting. The growth of animáis can be retarded as well as it can he increased. Said Dr. Herdman to the Argus: "Why experiments show that the animáis will have an increase up to a certain point and then the curve will decline rapidly when treated for the depressing effect. I have not made up the average yet but the growth can certainly be retarded." Dr. Herdman has no doubt but that human beings subjected to simlar treatments will show similiar results but the difnculty in getting "material" for the experiments is obvious.
