TO MATHILDE OERSTED.
We dedicate this translation to you, as a slight token of our friendship, and of our lively recollection of your highly gifted father, whose various philosophical researches you followed with such deep interest. We sincerely hope that we may, in some degree, have fulfilled your father's earnest wish, that a true representation of his views of Nature should be presented to the English Public.
L. & J. B. HORNER.
