Show of electricity on the nerves tho the celebrated french electrician has been making investigations into the physiological effects ot of continuous and alternating electric currents continuous currents lave have no action on the nerves in order to contract a nerve near the diaphragm itis it is necessary to employ one ten thousandth part of 0 avolt a volt 11 contends that non excitability depends on oil the constitution and on the nature of the nerv norvea es the effects of 0 alternating currents aie are quite different it la Is necessary first ot of all to distinguish between currents of low frequency and currents of 0 high frequency fie quency if ft a current ia i passed between the two hind paw paws a ot of a dog log or between one front and ono one hind paw f respiration I 1 is suspended in the case ot of an accident by alternating currents artif artificial leial respiration should be performed for some time A caie case is on record ot of a dog which was MR brought to life after twenty minutes ces bation of breathing after respiration I 1 is pei formed it is possible to pasa a currant of 1000 volts its and ono ampere without kill ing the tile animal but the contract contractions iong which follow ralie rale the tile temperature from 38 to 45 4 deg at theand the end of twenty tw only five flye min almin utes and the animal then dies from fron the effects of the heat beat on the heart death can bo be pre prevented anted under these conditions by exposing the body to cold in electrical executions it has been noticed that the temperature risea rises abo above e the normal limit this elevation of temperature is call cauca not by the electrical energy but by the contraction of the muscles which are operated upon new york telegram |
