Studies in Light Production (Classic Reprint)

Excerpt from Studies in Light Production These studies were written with the purpose of collecting information about the efficiency of our artificial illuminants as energy transformers, both for the sake of rendering the facts readily accessible and also for information as to the lines future progress is likely to take. From this standpoint photometry is not important, and consequently it has not been considered. The principal scientific journals have been worked through for the past twelve years, but the references to the literature given in the different chapters are not complete, the less important Papers being omitted. Ten of the twelve chapters have already appeared in The Electrician in a slightly different form, and I am indebted to Mr. W. R. Cooper, Editor of The Electrician, for several valuable suggestions. I am also indebted to Prof. A. Gray, F.R.S., LL.D., for the benefit of his criticism. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
