De Magnete magneticisque corporibus, et de magno magnete tellure. By William Gilbert. London, 1600, folio.--There is a second edition; and a third, according to Watt.[91]
Of the great work on the magnet there is no need to speak, though it was a paradox in its day. The posthumous work of Gilbert, "De Mundo nostro sublunari philosophia nova" (Amsterdam, 1651, 4to)[92] is, as the title indicates, confined to the physics of the globe and its atmosphere. It has never excited attention: I should hope it would be examined with our present lights.
