482 Dr. M. Wildermnnn on Real and Apparent 



values of t' — t", since under new conditions the value of K 

 changes in different ways (the surface of the separated ice 

 becomes different, &c, <fcc.) In our subsequent calculations 

 we shall assume for K the minimum value found above, this 

 being more reliable. 



From the above experimental data it follows : — 



A. //' the Convergence Temperature is above the Freezing 

 Temperature.
