The eflect of the graduated ajiplication of twist does not 

 sensibly differ from that obtained by applying the maximum 

 twist at once.

The etfect of a constant twist on magnetization is to ineroiise 

 the magnetization in weak fields and to diminish it in strong 

 lields. As for curves (^^V, //)-,/• (dotted lines in Figs. 21 and 

 22) deduced fi'om (/, If)-.,r, the general course is quite similar 

 to that of the curves obtained from (''^,, '),i,r\ but (juantita- 

 tively there is some ditference between these two. The difterence, 

 however, becomes less with increased tension.
