The cause ofthe two directions and two grades of electricity will be shownunder the head of Galvanism, in XXXIV of this chapter. XXXI. DlAMAGNETISM. 1. If an iron nail or other magnetic substance should be sus-pended from the middle between the poles of a horse-shoe mag-net it will immediately arrange itself in the magnetic axis and DIAMAGNKT1SM. 133 point to the north and south pole thus, N—S, but if a piece ofbismuth, or phosphorus, or antimony,should be suspended in thesame way, it will be arranged equatorially or atright angles to the axis as in fig. 142. Suchsubstances are diamagnetic, and they are com-monly supposed to repel the magnetic , as I have learned, is a mistake and theyassume that position because the diamagneticaxis crosses these substances laterally in-stead of longitudinally, as is done in the caseof magnetic substances: thus the followingrepresents a diamagnetic substance betweenthe magnetic poles :—. 142. Horse-ShoeMagnet. Magneto-electricity flowing from thepositive pole of the magnet, through the ?».?substance laterally and into the nega-tive pole of the magnet. I Chemico-electricity flowing from thenegative pole of the magnet in oppositedirection into the positive or north poleof magnet. The following represents the axis of a magnetic substance:— Magneto-electricity flowing frompositive pole of magnet through the jj-substance longtitudinally and enteringthe positive pole of magnet. Chemico-electricity flowing from-S negative pole of magnet in oppositedirection and entering the positive poleof magnet. 2. A little better conception of the distinctions which seem to arrange all substanc
