| Title | Unpublished manuscript, 'On the relative dynamic value of the degrees of the compass, and on the cause of the needle resting in the magnetic meridian' by Graves C [Champney] Haughton |
| Date | 16 June 1846 |
| Description | After ascertaining the distances at different azimuths at which a bar magnet placed with its axis directed to the centre of a magnetic compass needle causes the needle to assume the position in which its axis is in the same line with that of the magnet, Haughton finds that these points of distance form a peculiar curve, which is nearest to the centre of the magnet at the east and west azimuths, and recedes from it as it advances to the north and south; and is twice the distance from it at the north than at the south azimuths.
Includes one page of figures of Haughton's experiment.
