1. In a previous communication to the Royal Society experiments conducted in the Physical Laboratory of University College, Reading, have been described, from which it appears that the rate of consumption of carbon from the cathode of a very short are is such that the departure of one atom is accompanied by the transference between the poles of four electronic charges. The loss of weight of the anode is larger than this, on account of subsidiary combustion or evaporation occasioned by the high temperature of the crater. An experiment bas been described in the paper referred to which demonstrates the supreme importance of a hot cathode; the are could be maintained with a hot cathode alone, but not with a hot anode alone. It was suspected in consequence of this that the anode consumption of carbon was unimportant, and the experiment was repeated in the following manner for the purpose of testing this.
