however, and it may be safer to conclude from the limited data 
(and considering the discrepancies shown by the repetitions) 
that the most promising total concentration lies within the range 
between these two, perhaps nearer to the lower limit than the 
upper. 
Reverting to Table 5 and taking up now the comparative 
physiological values for top yield of the various sets of salt 
proportions for the two medium total concentrations, it will be 
instructive to study the agreements and disagreements between
