During the year 1596, Jean Jacques Vuccher published “De Secretis” (“The secrets and marvels of Nature”), wherein, at p. 166, he thus advises the application of a loadstone for curing the headache: “La pierre d’aymant appliquée et mise contre la teste, oste toutes les douleurs et maux d’icelle-ce que nostre Hollerius escrit comme l’ayant prins [sic] des commentaires des anciens.” And, in 1754, Lenoble constructed magnets that were readily used in the treatment of various diseases (“Practical Mechanic,” Vol. II. p. 171).

The application of the magnet for the relief of various complaints is treated of at pp. 334–335, Vol. II. of J. Ennemoser’s “History of Magic,” where will be found a list of works containing accounts of the oldest and most extraordinary known cures on record. Additional references to cures by the magnet, as well as with iron or amber—besides those named more particularly at A.D. 1770 (Maxim. Hell) and at A.D. 1775 (J. F. Bolten)—are to be found in the following works:

“The magnet ... gives comfort and grace, and is a cure for many complaints; it is of great value in disputes. When pulverised, it cures many burns. It is a remedy for dropsy” (I Sermone ... di F. Sacchetti ... § 18).

According to Dias, “the magnet reconciles husbands to their wives,” and Platea remarks that “it is principally of use to the wounded,” while Avicenna says “it is a remedy against spleen, the dropsy and alopecian.”

A.D. 543.—The Japanese say that at about this date the Mikado received from the Court of Petsi in Corea “the wheel which indicates the south.”

A.D. 658.—As shown by Kaï-bara-Tok-sin, in the “Wa-zi-si,” the first magnetic cars were constructed during this year in Japan; the loadstone was not, however, discovered in that country until A.D. 713, when it was brought from the province of Oomi (Klaproth, “Boussole,” p. 94). The “Journal of the Franklin Institute” (Vol. XVIII. for 1836, p. 69), gives a description and illustration of one of these magnetic chariots, taken from the thirty-third volume of the Japanese Encyclopædia.

A.D. 806–820.—Between these dates, under the Thâng dynasty, were first made the cars called Kin-Koung-yuan, which were magnetic chariots similar to those previously known, but bearing in addition a drum and a bell. Both the latter were struck at regular intervals by an erect male figure placed at the head of the car (“American Journal of Science and the Arts,” Vol. XL. p. 249).
