The actual direct benefits from Gastron 

 are a known quantity, 



Unmistakably experienced by the patient, 

 observed by the physician — in disorders of gas- 

 tric function. 



Inevitably the better digestion promotes 

 better nutrition, strengthens resistance, encour- 

 ages and heartens the patient, thus promotes 

 a condition of body and a state of mind con- 

 ducive to restoration. 



In these circumstances there is an appeal 

 for a wide application of Gastron; far-reaching 

 indeed be its ultimate good effects.
