bilities calculated by Goodwin. The solubilities in the last column do 

 not show as good an agreement ; but I do not feel sure that this proves 

 that the formula by which they are calculated is wrong. It seems to 

 me quite as probable that these figures represent the actual solubilities 

 in the cells examined by Goodwin ; but not the real solubilities of
