No figure is given for the results obtained on November 6, L906, and 

 collected in Table VI. The curves are very >teep. 



See Figure 11 for the magnetization curves corresponding to Ti 

 VII and VIII, of November L6, L906. The curves passing through the 



crosses are the ones obtained by using the method of steps, while the

ones through the dots were found by means of the reversal method. 

 The vertical arrow-points indicate the probable position of the normal 

 curve by steps, and the oblique arrows give the reversal one. .Several 

 series of step curves were taken for each lit so that a good average 

 curve could be constructed. It will be noticed that the step curve- 

 all lie below the others, except the one for m = 400.
