Mr. F. G. Baily. The Hysteresis of 



Fiq.S. 



Further experiments with the tube placed horizontally so that the 

 magnetic lines cut the cathode rays produced the usual deflection of 

 the latter, but did not seem to have any appreciable effect on the 

 internal resistance of the tube.

(Abstract.) 



That the hysteresis of iron varies with the conditions of magnetic 

 change has been ascertained in some instances, notably those in which 

 the attractions between the molecular magnets of the Weber-Max- 

 well-Ewing theory are diminished by super-imposed vibrations in the
