Country of manufacture


Categories: Medicine, Quack Medicine


A C1887 mint and boxed example of Ferdinand De Boyeres “Carolus” electro-magnetic battery pendant with suspension cord. Diameter: 4 cm. It is constructed of steel, lead, copper and brass. “The accompanying advertisement from the 5th edition of L’Imparial on Sat 3rd April 1887 claims that using this medal with a double electric current would protect the wearer against numerous illnesses by regeneration and purification of the blood.” Thanks to Laurie Slater of the Phisick site for the ad. While Carolus batteries do occasionally turn up, boxed examples are extremely scarce, and unused examples even more scarce!
