 In a very early stage of electro-magnetic experiments it had been suggested that an instantaneous telegraph might be established by means of conducting wires and compasses. The details of this contrivance are so obvious, and the principle on which it...  The Edinburgh Philosophical Journal - Page 1051825Full view - About this book
