"This book has been called one of the first truly scientific books published in England. It is the first English work devoted to the use of the compass, and it contains Norman's proposal for a magnetic field of force acting independently of matter - one of the most important concepts in the history of science. William Gilbert credits Norman with the discovery of the phenomenon of dip of the magnetic needle" (Tomash & Williams).
Borough's work is always found as the second part of Norman's New attractive.
