Fig. 7 represents the whole machine asnow actually working in the Palais dellndustrie. We have described the generating ma-chine before completing the descriptionof the system of distribution of thecurrent, because we ought to speakof the system of control used inmaking the current uniform when its in-tensity has been modified by a variationin its distribution ; that is to say, follow-ing after a variation resulting from theunexpected suppression of a certain num-ber of lamps in a part of the necessities of this system are easilyunderstood, if we consider that this sup-pression can lead to a greater or less in-crease in the intensity of the currentfeeding the remaining lamps. In France several systems have beendevised to obtain an automatic regula- 20 tion, but in America, i
