on 



resistance galvanometer. The calibration o£ the galvanometer 

 was made by using a mercury thermometer and a petroleum- 

 ether thermometer. 



Since the character of the pure metals and the reversible 

 nickel-steels was 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 percentage-contents of nickel were jess than 29'24 per 

 cent, (excluding 25 per cent. Ni). 



(a) Magnetization of Nickel-Steels. 

 The observed values of the intensity of magnetization are 

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

 as before.
