This comparison of the activity of the sound-ether, as the form-creating element in nature, with Chladni's phenomenon is drawn correctly only if we recognize that the conception of form, as an expression of that which is called forth through the etheric forces in nature, comprises more than the external spatially bounded shape of an organic or inorganic entity. Apart from the fact already indicated, that for the formation of such entities the co-operation also of life-ether is necessary, we can judge the activity of sound-ether correctly only if we conceive it as a much more inward activity, compared with the formation in external space of Chladni's figures. In the latter case, the reason why the influence of sound causes nothing beyond the ordering of form in outer space is because on this plane of nature the only changes that can occur are changes in the positions of separate physical bodies. Where the forces of sound in ether-form are able to take hold of matter from within, they can produce changes of form of a quite different kind. This effect of the activity of sound-ether has given it its other name: chemical ether.
