Abstract |
Among the various papers published upon the subject of municipial control of public electric lighting the showing made by the statistics of cost is always an important factor. Whatever be the point of view of the writers, they seem to present their own figures and yet to arrive at essentially inconsistent results. What I propose to do here, then, is simply to touch upon a few of the limitations which must be borne in mind by anyone who wishes to give these statistics their due scientific weight. |
