The gcdvcmometer suitable for physio- logical experiments is one having very many coils of extreme- ly fine wire, and so adapted to indicate the presence of currents of slight intensity. In order that it may be ascertained definitely that the cur- rents that deflect the galvanometer needle do not originate out- side of the muscle itself, non-polari»dble electrodes very care- fully made must be used, for the contact of ordinary metallic electrodes with living tissues suffices of itself to generate an electric current, as may be simply illustrated to one's self by placing two coins, one silver and the other copper, in contact with the upper and under surfac-es of the tongue respectively, and meeting in front; a peculiar taste results fronl the current excited. The construction of the non-polarizable electrodes common- ly employed, and as arranged for use, is diagrammatically rep- resented below (Fig. 186). Assuming the apparatus for the detection of electrical cur- rent in muscle to be in working order, a muscle from one of. Fio.
