The experiments which form the subject of the present communication were carried out two years ago, and supplement results already published. A brief note of some of the results was read before the Society in June 1904, and was also read before the British Association Meeting at Cambridge in August of the same year.
The previous paper discussed the effect of high temperature on the relation between electrical resistance and magnetization when the wire was magnetized longitudinally, that is, in the direction in which the resistance was measured.
The present results have to do with the effect of high temperature on the relation between resistance and magnetization when the magnetization was transverse to the direction along which the resistance was measured.

page 547 note † It is of great importance to make sure that, when the flat nickel coil is magnetized, the lines of force are directly transverse. A slight component of field along the wire brings in the longitudinal effect which may, under certain conditions, affect the sign of the change of resistance, especially in low fields. It was only after several trials that a satisfactory flat coil was obtained.
