a force of 0*65. The remarkable feature here is the low temperature 

 at which the change between magnetisable and non-magnetisable 

 occurs, whether the temperature is rising or falling. Comparing it 

 with, the last sample, we see that the character of the material with, 

 regard to magnetism is entirely changed.
