FIRST EDITION of this monumental work, which gives England the glory of being the absolute birthplace of electrical 

 science, and is ' one of the finest examples of inductive philosophy that has ever been presented to the world ' (Lord 

 Kelvin}. It was the first great work on natural science ever published in England, and here and abroad at once exerted an 

 enormous influence on the development of the newly-created science. It was so celebrated a hundred years after as to 

 call forth Dryden's well-known lines 'Gilbert shall live till loadstones cease to draw, 



Or British fleets the boundless ocean awe '. 



The first edition is of well-known rarity. Professor Silvanus Thompson, F.R.S., writing on the work in the ' Electrician ' 

 of March 24, 1905, says, ' This book is much rarer than the first folio Shakespeare, for while of that ivork no fewer than 156 

 copies are known to exist, there are only 68 copies of the first folio Gilbert knovjn, and only two have been sold in the book-auctions 

 during the last twenty years.' 



8401 On the LOADSTONE and MAGNETIC BODIES, and on the GREAT MAGNET the EARTH: a 



New Physiology, demonstrated by many Arguments and Experiments : a Translation [with LIFE 

 (pp. 19)] by P. FLEURY MOTTELAY, with portrait, 4 fs. title-pages, and numerous woodcuts 

 reduced from those of the first edition, roy. 8vo. cl., uncut, t. e. g. (SCARCE), 1. 15s 



London, or, New York, 1893 



THE FIRST ENGLISH TRANSLATION. It contains fs. reproductions of the woodcuts in the first edition, and fs. title-pages 

 of the first three editions, and Gilbert's ' De Mundo Nostro Sublunari Philosophia Nova' (1651). 



8402 On the MAGNET, MAGNETICK BODIES also, and on the GREAT MAGNET the EARTH ; a 



new Physiology, demonstrated by many arguments and experiments [translated from the First 

 Edition, by SILVANUS P. THOMPSON, SIR JOSEPH L ARMOR, RAPHAEL MELDOLA, LATIMER CLARK, 

 SIR BENJAMIN WARD RICHARDSON, FF.R.S., and others, with Index], with all the numerous wood- 

 cuts in exact fs. from those of the first Edition : NOTES on the DE MAGNETE of DR. WILLIAM GIL- 

 BERT [edited by SILVANUS P. THOMPSON, F.R.S.], with engravings 2 vols. sm. folio in 1, finely 

 printed on handmade paper at the Chiswick Press ; limp white vellum, with silken tiers (SCARCE), 

 4. 4s Gilbert Club, 1900-1 



1 This version has been prepared from the famous and rare original folio Latin edition of 1600, and is, as far as circum- 

 stances would permit, a facsimile (in English) of that edition. The translation is a page for page version ; all the cuts and 

 the finest of the ornamental initials having been reproduced in fs. A short index has been added to the text . . . The 

 edition is limited to 250 copies.' 



The greatest achievement of the De Magnete was the establishment of the magnetic nature of the earth, which Gilbert 

 proved analogically by his terrella, a large loadstone cut into the shape of a sphere. 



In electrical nomenclature he created the terms electrica and non-electrica in discovering the fact that many other 

 substances besides amber and jet (then alone supposed to possess it) have an electric action. From the word electrica 

 Robert Boyle afterwards derived the term electricity as used at the present time. 



One of Gilbert's most noteworthy discoveries, among the many contained in his book, is that of the earliest electro- 

 scope ever devised the needle one. 



' His work contains all the fundamental facts of the science, so fully examined indeed, that even at this day we have 

 very little to add to them.' Dr. Whewell. 



Prof. Silvanus Thompson's ' Notes ' are not only an indispensable commentary, but a valuable contribution to the 

 early history of magnetism and electricity. 



With GILBERT, NEWTON, and DARWIN England may be said to have opened the windows on the constitution of the 

 physical universe.
