It iswell adapted for the illumination of examination lamps, minor cauterywork, and operating motors. It is of the zinc and oxide of copper type, 38 Fig. greatly improved, and develops a large amount of energy. The electro-motive force is about one volt. Internal resistance .04 of an ohm, or prac-tically ;///. It operates equally as well on closedor open circuits. The points of superiority as determined bycareful tests and practical demonstrations are:Long life, discharging at a rate of eight centiam-peres for six months without any attention ; effi-<:iency, free from local action; no gases or odors,and maximum energy. Instruments for Measuj-ing Electricity.—Theinstruments for measuring electricity are quitenumerous, and some of them are very is necessary here to describe only a sufficientnumber to illustrate the principles involved. Galvanometers.—A galvanometer is an in-strument for indicating the presence and direc-tion of a current, and for measuring its are
