. Journal. as found to be, inthe most reliable experiments, between the limits17-6 : 0 25 and 10-8 : 0-36. The conclusion isdrawn tliat the anode loss of carbon is unimportantin the mechanism of the arc, and that the mainfunction of the anode is to receive the carriers ofthe current produced by the essential processoccurring at the surface of the cathode. Thedifferences in potential between the poles for arcswith rotating and fixed poles have also beendetermined, the former being smaller though thearc is greater, and this is accounted for by thereduction of electronic emission from the anode.
