The initialelectro-motive forceof this cell variesbut little from It polarizesvery rapidly on solow an external re-sistance as 5 ohms,while the internalresistance, which isdifferent for cells ofdifferent size,is veryirregular during theworking of the a cell should be employed only for intermittent service, where thecircuit is kept closed for short periods only. In such situations it willdoubtless prove efficient and durable. Its convenience, particularly in the hands of unskilled persons, is muchin its favor. BATTERIES WHICH HAVE STANDARD OFELE
