On the ^\i)ole the cominitefl course of' the Txk and p^ck agrees 

 fairly well with the observations. The on\y important discrepancy is 

 that from the observations of mixtures of HCl and CJI„ Ihere follows 

 a minimum for the critical temperature, while the compulation would 

 not have predicted this circumstance. This uiinimum, howc\'er, is not
