What constitutes Mr. Edisons systemis not alone his lamps, it is the totality ofthe arragements referring to them andwhich have attained such a degree ofsimplicity that henceforth nothing re-mains to be desired in practice. Gene-rating machines, distribution of circuits,installation, indicating and regulatingapparatus, meters for measuring theamount of current employed are all com-bined for immediate application. Aswe have said, this application is aboutbeing made in a part of the city of NewYork, where a great number of housesare to be lighted by this system, bymeans of a subterranean distributionfrom a central station, from which alsomotive power will be distributed to thehouses. This central station will be providedwith twelve steam engines of 150 horsepower each, actuating dynamo-electricmachines, each of which
