Not illustrated. 1885 edition. Excerpt: ...I resumed, as I had promised, my researches on this element. These researches have lasted longer than I expected: a circumstance all in favour of the new element, because this long duration is mainly due to the fact that its electromotive force was almost constant for weeks, even when, for reasons which will appear below, I substituted continuous for intermittent working. It further happened that when the last series of my experiments was completed, researches of another nature compelled me to defer the summarising of the results for more than two months. It need not be said that I took care not to repeat the error which in my first series of researches reduced my alkaline solution 7 per cent, below the strength which 1 intended. The present element contains 900 grammes of solid caustic potash, 2,100 grms. of water, and 900 grms. oxide of copper. In the calculations which will appear in this studv I fixed the internal resistance of the element at 0-075 ohm. This value was the mean of my former results, and might be deduced from them with more exactitude than from those the results of which I am about to communicate. La Lumiere Electrique. March 28, 1885. that in the method which I have taken, this exactitude increases with the difference of potential v--r, betweea two parts of the external circuit, which, nevertheless, may be separated only by a part of the circuit, the resistance of which, i, is great. And we attain this twofold object only when (as was the case in my former experiments) the strength of the current is great in consequence of the slight external resistance. Therefore as these new series of experiments are only made to see up to what point, with an augmentation of the onter resistance and with a corresponding decrease of...
