Engraved title & several engravings & numerous woodcuts in the text. 8 p.l., 412, [12] pp. Folio, cont. half-sheep & marbled boards (minor worming towards end), spine gilt, black leather lettering piece on spine. Ferrara: F. Succius, 1629. First edition, Jesuit issue, and a very fine copy. "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."-Wolf, A History of Science, Technology, and Philosophy, I, p. 303. 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… Read More

Ferrara: Francesco Suzzi, 1629. First edition. UNIQUE PRE-PUBLICATION PRESENTATION COPY. First edition, a unique pre-publication presentation copy by Cabeo to his teacher Jacobo Corrado, of the first extensive study of magnetism since William Gilbert's De Magnete (1600).

The central focus of his work, like Gilbert's before him, was therefore the study of the magnetic behaviors of compass needles. Where Gilbert,… Read More
