ART. 6. K. HONDA AND S. SIIIMIZU. 



Since the character of the pure metals and the reversible 

 nickel steels were not much altered by cooling them in liquid 

 air, the measurements of the magnetization and the magnetic 

 change of length at the intermediate temperatures were confined 

 to only the irreversible nickel steels, that is, those, whose per- 

 centage-contents of nickel were less than 29.24?^ (excluding 

 25?^ Ni).

The observed values of the intensity of magnetization are 

 given in Table VIII. Here H and I have the same meaning as 

 before.
