§ 7. Before we draw the conclusions to be deduced from 

 this Table, we will again lay before us the alternatives which 

 are here to be decided. There are two cases possible ; either 

 the residual magnetism converges simultaneously with the 

 magnetizing force towards zero, or else the residual magnetism 

 reaches zero already for a finite value of the force. 



Now the Table shows that, at least with the more-elongated 

 ellipsoids, a value of the magnetizing force can be approxi- 

 mately fixed, at which the increment of the magnetism already 

 present (UM) first exceeds the errors of observation. Resi- 

 dual magnetism is first demonstrable for the following values 

 of the argument K and current-intensity i : —
