DISCUSSION AND COBBESPONDENCE 

 balanced solutions and nutritive solutions 



Mr. True's article on "Antagonism and 

 Balanced Solutions " ^ closes with the follow- 

 ing remarks. 



la both sea water and the more or less dilute 

 nutrient solutions present in the soil, normal life 

 is sustained, as a rule, only in mixtures of proper 

 proportions and necessary concentration. Since 

 salts are required in both cases to overcome the 

 harmful action of pure water, as well as that of 

 the salts themselves, there seems to be no reason to 

 seek to limit the use of the term "balanced solu- 

 tions" in the manner suggested by Loeb and 

 Osterhout. Unless we admit that malnutrition 

 due to a deficiency in nutrient salts is a form of 

 toxicity excited by the substances present, we can 

 hardly escape the alternative proposition that the 

 missing salts are injurious in absentia. 



Since the writer is responsible for the in- 

 troduction of the term physiologically bal- 

 anced salt solutions,- he may be pardoned for 

 pointing out that in his opinion neither of the
