First edition of the first major English treatise based on experimental methods; the first scientific treatise on electricity and magnetism.'The magnetic proprieties of the lodestone were known in ancient Greece, but it was only in the late Middle Ages that knowledge of the magnetic spread to Europe from China, where also the mysteries of magnetism had long been studied. But it was with Gilbert, who was physician to Queen Elizabeth I, that the modern development of electricity and magnetism really starts. His book ‘On the Magnet' was the first major English scientific treatise based on experimental method of research. Gilbert was chiefly concerned with magnetism; but as a digression he discussses, in his second book, the attractive effect of amber (electrum), and thus may be regarded as the founder of electrical science. He coined the terms ‘electricity', ‘electric force' and ‘electrict attraction'. His ‘versorium', a short needle balanced on a sharp point to enable it to move freely is the first instrument designed for the study of electrical phenomena, serving both as an electroscope and electrometer. He contended that the earth is a great magnet; he distinguished magnetic mass from weight; and he worked on the application of terrestrial magnetism to navigation. Gilbert's book influenced Kepler, Bacon, Boyle, Newton and, in particular, Galileo who used his theories to support his own proof of the correctnees of the findings of Copernicus in cosmology. It was printed eleven times, four in Latin, six in English and once in Russian'. (PMM)
