order, some shorter, some longer, some pleasant in sequence, some less so. In colour it is quite possible to have the same kind of arrangement, and many persons can, even at first sight, receive pleasure from such a colour phrase or melody, and can remember it perfectly. Both the power of recalling it and the pleasure of seeing it are, of course, rapidly increased by education of the eye, and it is quite true that it may need a long period of time for average audiences to gain an appreciation of colour-music at all equal to that they now have of sound. This is, however, not an argument against the art, but rather one in favour of giving increased opportunities for studying it. The writer went on to say that he fails to see how emotion can be awakened "unless a distinct faculty for appreciating tune is developed"; but in colour, just as in music, experiment shows that an emotional impression can be produced even by a sequence of two or three notes, and it is probable that colour is much more independent of definite melody or tune than is music.
