Series 2 and 3 differ from series i only in total salt concentration, the total 
calculated osmotic concentration values in these series being 2.1 and 4.2 
atmospheres respectively. Series 4 and 5 have the same total concentration 
values as series 2 and 3 respectively, but in the former NaNOs is used instead 
of Ca(N03)2. For purposes of comparison the standard nutrient solution 
proposed by Thorn (8) was here used as a check in each series (except series 
4), always with the same total osmotic salt concentration as that employed 
for the series in which it occurred. In Tables i and 2 are given the actual 
Table i . Partial volume-molecular concentration of the salts employed in the culture solutions 
of the series in group 1

partial volume-molecular concentrations of each of the solutions of the five 
series used in this study. The culture numbers refer to the positions which 
the cultures occupy on the triangular diagram^ graphically representing the 
series with respect to the osmotic proportions of the three salts employed.
