Note 1 — The Correlation of Vital and Physical Forces.

Humboldt, Views of Nature, Bohn’s ed., London, 1850, p. 380. This allegory did not appear in the first edition of the Views of Nature. In the preface to the second edition the author gives the following account of its origin: “Schiller,” he says, “in remembrance of his youthful medical studies, loved to converse with me, during my long stay at Jena, on physiological subjects.” * * * “It was at this period that I wrote the little allegory on Vital Force, called The Rhodian Genius. The predilection which Schiller entertained for this piece, which he admitted into his periodical, Die Horen, gave me courage to introduce it here.” It was published in Die Horen in 1795.
