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.
