The means for the three larger series are, in terms of osmotic 

 pressure, the following: 



Comparing, we find the differences shown below : 



Comparison Wall Prolification 



C and D 0.445 + 0.069 O-O16 + 0.074 



C and E 0.164 + 0.098 0.279 + 0.101 



D and E 0.281 + 0.091 0.295 + 0.085 



Thus, the differences between the series are not very large absolutely,
