Excerpt from Artificial Light: Its Influence Upon Civilization In the following pages I have endeavored to discuss artificial light for the general reader, in a manner as devoid as possible of intricate details. The early chapters deal particularly with primitive artificial light and their contents are generally historical. The science of light-production may be considered to have been born in the latter part of the eighteenth century and beginning with that period a few chapters treat of the development of artificial light up to the present time. Until the middle of the nineteenth century mere light was available, but as the century progressed, the light-sources through the application of science be came more powerful and efficient. Gradually mere light grew to more light and in the dawn of the twen tieth century adequate light became available. In a single century, after the development of artificial light began in earnest, the efficiency of light-production in creased fifty-fold and the cost diminished correspondingly. The next group of chapters deals with various economic influences of artificial light and with some of the byways in which artificial light is serving man kind. On passing through the spectacular aspects of lighting we finally emerge into the esthetics of light and lighting.
