To enable you to judge more fairly of the evidence, I have attempted to present the subject in an inductive rather than in a deductive form. Instead of starting with a number of hypotheses, originating you would not know how, and then showing how the conclusions following from them are in accordance with observed results, I have commenced with only the most fundamental conceptions of undulations, and of the conditions which we must suppose to obtain in order that they may exist, and have afterwards supplemented our original rather crude conceptions in the manner which a study of the phenomena showed tobe necessary. We have seen that not merely are the laws of reflection and refraction in agreement with the theory, but the curious and complicated phenomena of interference and diffraction are explained by it to the minutest particular. What strikes one most about the theory is what has been truly described as its astounding simplicity. This so carries on the face of it the stamp of truth, that to one who is familiar with the phenomena as well as the theory, an overwhelming conviction is produced that it is indeed true to nature. That being the case, it may be well now to examine the various hypotheses which must be made in some greater detail than has hitherto been done.The fundamental hypothesis of the existence of a medium to... ...
