Note 3 — Chapter VII

Whether one attributes nervous energy to a chemical or an electrical process, one must still regard it, if not simply as the play of the vibration of minutest atoms, yet as in the main excited or accompanied by this, whereby the imponderable has a larger part than the ponderable. Vibrations, however, can only apparently expire by extending themselves into their environment, or if indeed they disappear for a time through translation of their living strength into so-called elasticity, yet, according to the law of the conservation of energy, they await a revival in some other form.
