    CHAPTEE I. AGREEMENT OF THE MUSICAL AND COLORIPIC RATIOS OF VIBRATION, THE BASIS OF THE ANALOGY OF SOUND AND COLOUR. SECTION I. Introductory RemarJcs, and ex'position of the ratios of Musical Vibration. The plienomena of Light and Sound mutually illustrate each other, and the more tliej are studied and compared, the more it becomes manifest that both are obedient to the same essential laws and governing principles, though the vibrations of the one may be represented as almost infinitely more minute and subtle than those of the other. A great interval, therefore, may be said to exist between the smallest sonorous and the largest colorific vibration. Moreover, the vibrations of the colorific scale are within very narrow limits, embracing but a single octave, whilst musical vibrations, extending over numerous octaves, take a much wider range. Nevertheless, the internal
