lo Grindlkv, Thermodynamics of SuperJiented Steam. 



The results recently published by Callendar, and briefly 

 referred to previously, appear to be of similar character 

 to those obtained by the above process from Ramsey and 

 Young's experiments, and in his paper it appears that 

 his results on the specific volumes of saturated steam have 

 been obtained by a deduction from some of the properties 

 of superheated steam, and, therefore, by a process similar to 

 that just adopted with the results of Ramsey and Young's 

 experiments. The main difference is that in Callendar's 

 paper the deduction was made from a knowledge of the 

 cooling effects and specific heats Kp'xw superheated steam, 

 while in the other case the deduction was made from a 

 knowledge of the densities of superheated steam. 



To see whether there was any agreement between 



the results so obtained by these two processes a few values 



found for the specific volumes of saturated steam deduced 



from Ramsey and Young's results, have been placed in 



the following table with a few of Callendar's results, and 



with the specific volumes determined from Regnault's 



latent heats.
