SCIENCE cannot complain of neglect by modern society. Her methods, her discoveries, her inventions, are greeted with appreciative applause. Even her terminology, technical and complicated as it may be, is rapidly absorbed into the popular phraseology of the day. In truth, scientific terms often supply for many a speaker, befogged in his own rhetoric, a happy explanation of the complex and problematical, and a short cut to the conclusion of a controversy. This ready use of the language of science is not, however, all gain, for the very ease with which scientific terms are made to do service helps obscure those implications which are vital to the subject.
