The thermo-electric power Unes for the remaining metals were 

 drawn in this same manner. 



Conclusion. The preceding work was performed primarily 

 with a view to investigating the thermo-electric characteristics 

 of ''advance," "climax/' and "manganin" substances whose 

 thermo-electric lines are not found on the text-book diagrams. 

 The subsequent plotting of these lines is of no little interest. 

 But as a check, the metals, nickel, mercury, iron, copper, whose 

 lines are well known, were investigated, plotted, and the thermo- 

 electric lines found to agree with existing diagrams within reason- 

 able limits.
