THERMO-ELECTRIC EFFECTS OF LONG. TENSION IN DIFF. METALS. QJ 



not peculiar to that metal." In fact, that which makes iron (and also 

 steel) magnetically remarkable and thermo-electrically singular, seems 

 to have its ground m the characteristic molecular constitution of that 

 metal. In other metals examined, the thermo-electric hysteresis with 

 respect to longitudinal tension is either very insignificant or entirely 

 absent. In them, excepting nickel, changes of E. M. F. are nearly 

 proportional (either increasingly or decreasingly) to the loads applied.
