Abstract
The present paper is the outgrowth of the discussion in connection with the paper on condensers at the last meeting of this society. The method previously described has been applied to measuring the efficacy of small condensers as compared with the standard 4.5 inch, for sources and projection lenses of a variety of sizes. A graph showing the relation between brilliancy of incandescent filaments and lamp life has been added.
