Condition

First edition, first issue. The First Work to Discuss Electrical Repulsion. This admirable work on electricity and magnetism is the only direct continuation of De magnete by William Gilbert, the father of electrical engineering. Wolf: "Perhaps the most significant discovery of the century following Gilbert was that of electrical repulsion. This effect seems first to have been noticed incidentally by Cabeus, who, in his Philosophia Magnetica (1629), describes how filings attracted by excited amber sometimes recoiled to a distance of several inches after making contact." Wheeler Gift: "On p. 194 of this famous work of the great Italian Jesuit will be found the first recognition of electrical repulsion. Gilberts discoveries and theories are freely discussed, the latter often adversely. Sympathetic telegraphy disproved (page 301); magnetic field mapped out by iron filings; also diagrams of the magnetic (lovers) telegraph. Cabeo opposed the views of Copernicus on astronomy, as well as those of Gilbert on terrestrial magnetism. Copies of this first edition are much sought after." Mottelay: "An important work on the loadstone... A curious chapter...institutes a comparison between electrical and magnetical attraction...The Philosophia Magnetica is the second Latin book published on electricity." Cabeo also relates his many experiments on the possibility of telegraphic communication by means of magnetized needles and gives the first picture of the sympathetic telegraph, an imaginary magnetic telegraph which sometimes appeared in early electrical literature, fancifully prefiguring the actual telegraph. There are three issues (no priority) of this book: the first issue has a royal coat,of,arms at the head of the title; the second issue has the coat,of,arms replaced by the Jesuit emblem; and the third was produced for export to Germany and has an added printed title with a Cologne imprint.
