Note 42 — Book VI
Reading edition
“Philosophia magnetica in qua magnetis natura penitus explicatur....” An important work on the loadstone, in which the author often confutes the published treatise of Dr. Gilbert of Colchester, and quotes the inedited writings of L. Garzoni, who, even before Gilbert, had made researches respecting the magnet. A curious chapter in the “Philosophia” institutes a comparison between electrical and magnetical attraction (Libri, “Catalogue,” 1871, Part. I. p. 161).
