As, when embodied along with other matter in its permanent form, this postscript will be seen by comparatively few, it has seemed desirable to give it a wider diffusion by publishing it separately.]
AN opponent, or partial opponent, of high authority, whose views were published some fourteen years after the above essay, must here be answered: I mean Mr. Darwin.

I have aimed to show that music has its germs in the sounds which the voice emits under excitement, and eventually gains this or that character
