    Hardcover. Condition: Nearly Fine. First edition. 1/250. Two parts, folio. [16], 246, [2, colophon & blank]; iv, 67, [1, blank]pp. With bibliographical references and index; separate title for the Notes (dated 1901); decorative initials and ornaments; diagrams throughout (1 folding). Full limp vellum, spine lettered in gilt; green silk ties. Offsetting at endleaves from ties; a few pages with touches of mild to light foxing. A nearly fine copy. First edition (limited to 250 copies) of this English translation of the author's De Magnete, Magneticisque Corporibus et de Magno Magnete Tellure (London, 1600), reproducing the woodcut illustrations and diagrams of the original edition. The physician and natural philosopher William Gilbert (1544?-1603) "provided the first comprehensive and satisfactory explanation of the behaviour of the nautical magnetic compass." The present work, and the only one published in his lifetime, secured the author's enduring significance as it announced a new science of the earth. His rejection of the Aristotelian-Galenic theory of matter, along with the traditional division by Christian Aristotelians of the cosmos into a superior celestial world and an inferior terrestrial one was influenced by Bernardino Telesio and Francesco Patrizi, and especially the vitalist, infinite universe described by Giordano Bruno. Along with Francis Bacon, Gilbert "pioneered the iconoclastic modern positions that knowledge progressed, and that science needed to begin anew on empirical and experimental foundations" (ODNB).

Since the mind, Musschenbroek states in his Elementa physicae (1734), has no innate idea of what bodies and their qualities are, we can obtain knowledge about them only by observation and experiments. But we must be extremely careful, use good instruments, and take into consideration all circumstances -atmospheric pressure, temperature, locality, and weather. Thus we can discover the laws that govern the behavior of bodies, provided the results of experiments, repeated over and over again, are the same, and specific causes are admitted only when the phenomena investigated leave no doubt. The stress is therefore on induction; but deduction, for example, by means of mathematics, is admissible, as Newton had shown, provided such deductions are constantly tested by experiment. The success of such reasoning on the basis of careful experimentation finds its guarantee in the infinite wisdom of the Supreme Being" (DSB IX, 596). - P. van Musschenbroek (1692-1761) gilt als einer der Erfinder der sogen.

    First edition; folio (30.5 x 19.5 cm); text in Latin, woodcut title device and large woodcut arms on verso, one folding plate, 87 woodcuts in text of which 4 are full-page, decorative woodcut initials and head- and tail-pieces, title page trimmed, partially restored and washed (possibly from another copy), scattered light foxing; later calf with unidentified gilt armorial device to covers, gilt lettering to spine, short split to spine, extremities slightly rubbed, otherwise an overall very good copy; [xvii], 240, [2](blank)pp. First edition of the first great scientific book printed in England. William Gilbert, personal physician to both Elizabeth I and James I, gathered all known opinions relating to the magnet and put them to the test of experiment, thereby being among the first to initiate the experimental method of science. De magnete exemplifies pre-Baconian experimental philosophy by supporting new theories with empirically-derived experimental evidence, and these experiments were described in sufficient detail for the reader to recreate them. Gilbert also described his scientific instruments in great detail, including new ones such as the 'versorium': the first instrument to be used for the study of electric phenomena. Gilbert observed that the earth was a gigantic magnet and provided a physical basis for the Copernican theory. His work was cited by Digby, Boyle, Kepler and Huygens, and Galileo drew on Gilbertian magnetism to support his belief in a Copernican heliocentric cosmology in his Dialogo.

Large marginal asterisks mark what he considered great discoveries, and small asterisks minor ones. There are 21 of the former and 178 of the later. Gilbert shows that a freely suspended magnet is controlled by the earth and not, as supposed, by extra-terrestrial influences. his magnetic theory enabled him to explain the behavior of the compass-needle, the dip-needle, the magnetic condition of vertical masses of iron, and the magnetic properties of heated iron bars when allowed to cool while lying in the magnetic meridian. Gilbert is chary of prose and wrathful in denunciation; he was a staunch Coperican, and warm friend of Kepler and Galileo." [Wheeler Gift.] ".

Preserved in folding box. A crisp copy, in contemporary English binding, of the first edition of this ground-breaking, illustrated work on magnetism and electricity, by William Gilbert, the Galileo of Magnetism . The first major English scientific treatise based on experimental methods of research. It is with Gilbert that the modern development of electricity and magnetism really starts (PMM). Gilbert (1544-1603) was physician to Elizabeth I and James I, and a natural philosopher. His masterpiece, De magnete was based on experiments he carried out using a model of the earth called terrella , often portrayed in the woodcut diagrams. His use of electricus in the sense of like amber , here referring to its attractive properties, inspired Sir Thomas Browne to coin the term electricity in 1646. The 6 parts are devoted to lodestones (naturally-magnetized minerals, like Gilbert s own terrella ), magnetic movements, direction, variation, declination and the revolution of the Earth intended as a gigantic magnet. The second chapter of Book II is the earliest ever published on electricity (Mottelay, p.83); here Gilbert discusses his experiments on attraction using a rotating needle electroscope, and concludes by theorizing a differentiation between magnetic and electric bodies. The remainder of Book II deals, amongst others, with magnetic axis and poles, the spherical extension of magnetic force, and how it can be determined by mass or quantity. Book III discusses verticity or the force visible when magnetized iron turns the opposite way, as well as the magnetization of stones, with a large woodcut showing a scientist or ironmonger creating a magnet in his workshop. Book IV examines variations of magnetism in different places due to the Earth s rotation, as well as the construction of a mariner s compass, also portrayed; Book V is a study of the magnetic needle; and Book VI employs the Copernican theory to explain the magnetic nature of the Earth. The work contains a prodigious number and variety of experiments and observations [ ]. It would, indeed, be a miracle if all of Gilbert s general inferences were just, or all his experiments accurate. It was untrodden ground. But, on the whole, this performance contains more real information than any writing of the age in which he lived, and is scarcely exceeded by any that has appeared since (Mottelay, p.89). A very fine copy of this most important scientific work. Gilbert s book influenced Kepler (112), Bacon (119), Boyle (141), Newton (161) and in particular Galileo (128), who used his theories to suggest his own proof of the findings of Copernicus in cosmology (PMM).

    Hardcover. First edition. EVANS 26 - THE FIRST SCIENTIFIC TREATISE ON ELECTRICITY AND MAGNETISM. First edition of "the first major English scientific treatise based on experimental methods of research. Gilbert was chiefly concerned with magnetism; but as a digression he discusses 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 'electric 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 was one 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 [in the Dialogo] to support his own proof of the correctness of the findings of Copernicus in cosmology" (PMM). "Gilbert provided the only fully developed theory . and the first comprehensive discussion of magnetism since the thirteenth century Letter on the Magnet of Peter Peregrinus" (DSB). Although this book does appear with some regularity on the market, copies such as ours in fine condition and in untouched contemporary bindings are rare. "During the fifteenth century the widespread interest in navigation had focused much attention on the compass. Since at that time the orientation of the magnetic needle was explained by an alignment of the magnetic poles with the poles of the celestial sphere, the diverse areas of geography, astronomy, and phenomena concerning the lodestone overlapped and were often intermingled. Navigators had noted the variation from the meridian and the dip of the magnetic needle and had suggested ways of accounting for and using these as aids in navigation. The connection between magnetic studies and astronomy was less definite; but so long as the orientation of the compass was associated with the celestial poles, the two studies were interdependent . "Gilbert divided his De magnete into six books. The first deals with the history of magnetism from the earliest legends about the lodestone to the facts and theories known to Gilbert's contemporaries . In the last chapter of book I, Gilbert introduced his new basic idea which was to explain all terrestrial magnetic phenomena: his postulate that the earth is a giant lodestone and thus has magnetic properties . The remaining five books of the De magnete are concerned with the five magnetic movements: coition, direction, variation, declination and revolution. Before he began his discussion of coition, however, Gilbert carefully distinguished the attraction due to the amber effect from that caused by the lodestone. This section, chapter 2 of book II, established the study of the amber effect as a discipline separate from that of magnetic phenomena, introduced the vocabulary of electrics, and is the basis for Gilbert's place in the history of electricity . "Having distinguished the magnetic and amber effects, Gilbert presented a list of many substances other than amber which, when rubbed, exhibit the same effect. These he called electrics. All other solids were nonelectrics. To determine whether a substance was an electric, Gilbert devised a testing instrument, the versorium. This was a small, metallic needle so balanced that it easily turned about a vertical axis. The rubbed substance was brought near the versorium. If the needle turned, the substance was an electric; if the needle did not turn, the substance was a nonelectric. "After disposing of the amber effect, Gilbert returned to his study of the magnetic phenomena. In discussing these, Gilbert relied for his explanations on several assumptions: (1) the earth is a giant lodestone and has the magnetic property; (2) the magnetic property is due to the form of the substance; (3) every magnet is surrounded by an invisible orb of virtue which extends in all directions from it; (4) pieces of iron or other magnetic materials within this orb of virtue will be affected by and will affect the magnet within the orb of virtue; and (5) a small, spherical magnet resembles the earth and what can be demonstrated with it is applicable to the earth. This small spherical magnet he called a terrella . "In discussing coition Gilbert was careful to distinguish magnetic coition from other attractions. For him magnetic coition was a mutual action between the attracting body and the attracted body. At the beginning of the De magnete he explained several terms that were necessary for understanding his work. One of these was "magnetic coition," which he said he "used rather than attraction because magnetic movements do not result from attraction of one body alone but from the coming together of two bodies harmoniously (not the drawing of one by the other)" (P. Fleury Mottelay, William Gilbert of Colchester . on the Great Magnet of the Earth, 1893, p. liv) . "Book III of the De magnete contains Gilbert's explanation of the orientation taken by a lodestone that is balanced and free to turn, that is, the behavior of the magnetic compass . the orientation of the compass was simply an alignment of the magnetic needle with the north and south poles of the earth. Gilbert gave numerous demonstrations of this with the terrella as well as directions for magnetizing iron. "By the end of the sixteenth century, navigators were well acquainted with variations from the meridian in the orientation of the compass. Thus, after discussing orientation, Gilbert turned in book IV to the variations in that orientation. Here he again used the comparison of the phenomena that can be demonstrated with the terrella and those that occur on the surface of the globe. Just as a very small magnetic needle will vary its orientation if the terrella on which it is placed is not a perfect sphere, so wi.

First edition of the first great work of experimental physics published in England; a scientific sturdy of electricity and magnetism. By his commitment to subjecting all theories to experiment, Gilbert became "among the first to initiate the experimental method of science" (Dibner). This work is one of the finest examples of inductive philosophy and even more remarkable for its publication two decades prior to Bacon's Novum Organum, where that method was actually explained for the first time. Throughout the De Magnete Gilbert discussed and usually dismissed previous theories concerning magnetic phenomena and offered observational data and experiments which would support his own theories. Most of the experiments are so well described that the reader can duplicate them if he wishes, and the examples of natural occurrences which support his theories are well identified. When new instruments are introduced (for example the versorium, to be used in identifying electrics), directions for their construction and use are included" (DSB).Gilbert's work is "the first major English scientific treatise based on experimental methods of research:" (PMM). Published only after eighteen years of personal study and experimentation, this book has Gilbert's new discoveries marked in the margins with large and small asterisks to denote whether they were significant or minor. Among the 21 major and the 178 minor discoveries is the conclusion that the earth is one large magnet (an assertion that led Galileo to study magnetism), as well as the invention of the versorium, his electroscope or electrometer, the first instrument devised to measure electrical phenomena. His magnetic theory enabled him to explain the behavior of the compass-needle, the dip-needle, the magnetic condition of vertical masses of iron, and the magnetic properties of heated iron bars when allowed to cool while lying in the magnetic meridian. In Book 2, which was intended as a digression into the importance of amber ("electrum") to magnetic studies, Gilbert coined the terms "electricity", "electric force" and "electric attraction" - clearly establishing his reputation as the founder of electrical science.Gilbert also claimed another, less coveted kind of scientific repute by coming to see magnetism as the explanation for almost all phenomena. This led Francis Bacon to attack him in his Sylva Sylvarum (1626) as being "one of those people so taken up with their pet subject of research that they could only see the whole universe transposed into the terms of it" (Butterfield, p. 56). This singular, scientific phenomena persists into our own days with numerous scientists currently describing major elements of the universe as working "exactly like the computer". All known copies have numerous ink emendations (not noted in the errata) which some have suggested shows that Gilbert saw the edition through the press personally. The present copy has manuscript corrections on pp. [vi], [x], 11, 14, 22, 39, 42, 47, 68, 130, 200 and 221. Contemporary limp vellum with overlapping edges. Spine lettered manuscript but faded. Foot of spine expertly repaired. Newer endleaves. Title lightly browned with a few tiny repairs, final few leaves evenly browned with lower margins repaired, some spotting. Cloth folding case. Overall, a lovely copy. PHOTOS AVAILABLE UPON REQUEST.
