A is a bank of lampsarranged in parallel multiple-arc. Two of the lamps are 16 , each carrying a little less than a half ampere ( ampere)* *Edison lamps. CHARLES JEWETT, , current. The others are 50 c. p. lamps, having each a currentcapacity of not quite one-and-a-half amperes ( amperes). Eachlamp turned on adds to the current an amount equal to its owncapacity. Such a bank is suitable for a twenty ampere Fig -5- which is an average cautery current. The system may be easilyextended to give thirty or forty amperes for heavier work. If aswitch-plug is placed in B, the right-hand section is ready forcautery; if in C, the left-hand section may be used for galvanism. I « _ t 3 E
