Paper, 'Theory of magnetism based upon new experimental researches' by [David Edward] Hughes

Description

Hughes writes: 'In a preliminary note [see PP/3/2] I communicated to the Royal Society the formulated results of a lengthened series of experiments with the induction balance, and I now present the experimental evidences which led me to these conclusions. From numerous researches previously made by means of the induction balance, the results of which I have already published, I felt convinced that in researches upon the cause of magnetism, I should have in it the aid of the most powerful instrument of research ever brought to bear upon the molecular construction of iron, as indeed of all metals. It neglects all forces which do not produce a change in the molecular structure, and enables us to penetrate at once to the interior of a magnet or piece of iron, observing only its peculiar structure and the change which takes place during magnetisation or apparent neutrality.'

Includes one page of diagrams of experimental apparatus and results.
