AN ARTIFICIAL OSMOTIC CELL 57 



CONCLUSION 



In conclusion it should be again remarked that the resem- 

 blances between this osmotic growth and the growth phenomena 

 of living things are very grossly superficial. The phenomena 

 of these precipitation tubes are of interest mainly because they 

 lead to a kind of physico-chemical thinking that is surely re- 

 quired in the analysis of many physiological processes. If it 

 is worth while for the beginner in cell physiology to attempt 

 to interpret the behavior of Traube's artificial cell, it is perhaps 

 worth while for him also to see this other form of artificial growth.
