CUBTK 5. 



absorption and liberation of heat occur at the same temperature as 

 the loss and return of the capacity for magnetism. From Curve 5 

 also we may infer that the latent heat liberated in cooling is about 

 150 times the heat liberated when the temperature of the material 

 falls 1 C. Concerning the latent heat absorbed in heating, nothing 

 can be inferred from Curve 4, excepting the temperature at which it 

 is absorbed.

In Table II are given the results of observations of induction in 

 terms of magnetising force at the ordinary temperature of the room ; 

 and in curve 6 these are plotted together with the curve for wrought 

 iron.
