JDF encloses a letter he received from William Thomson [not present], in which he answers a question JDF put to him regarding 'Faraday's and Tyndall's views of the polarity of Bismuth. For myself I can attach no meaning to the magnetic of space per se' [John Tyndall. On the Existence of a Magnetic Medium in Space, 1855].
