“From the remotest ages the philosophers have maintained the singular power of music over certain diseases, especially of the nervous class. Kircher recommends it, having experienced its good effects in himself, and he gives an elaborate description of the instrument he employed.
It was a harmonica composed of five tumblers of a very thin glass, placed in a row. In two of them were two different varieties of wine; in the third, brandy; in the fourth oil; in the fifth, water. He extracted five melodious sounds from them in the usual way, by merely rubbing his finger on the edges of the tumblers.
The sound has an attractive property; it draws out disease, which streams out to encounter the musical wave, and the two, blending together, disappear in space.
Asclepiades employed music for the same purpose, some twenty centuries ago; he blew a trumpet to cure sciatica, and its prolonged sound making the fibres of the nerves to palpitate, the pain invariably subsided.
Democritus in like manner affirmed that many diseases could be cured by the melodious sounds of a flute. Mesmer used this very harmonica described by Kircher for his magnetic cures. The celebrated Scotchman, Maxwell, offered to prove to various medical faculties that with certain magnetic means at his disposal, he would cure any of the diseases abandoned by them as incurable; such as epilepsy, impotence, insanity, lameness, dropsy, and the most obstinate fevers.”
