OSMOTIC PRESSURE OF AQUEOUS SOLUTIONS. 



Table 38 is a condensation of Sections A and B of Table 37. Section 

 D gives, for each of the ten concentrations of solution, the mean observed 

 osmotic pressure. Section E gives, for each concentration of solution, 

 the mean of the corrected osmotic pressures.

 Section D. Mean Observed Osmotic Pressures. 



*Not corrected; dilution unknown. 

 Table 39. — Mean ratio of corrected osmotic to calculated gas pressure. 



Table 39 gives, for each concentration of solution, the mean of the 

 ratios of the corrected osmotic pressures to calculated gas pressures. It 

 is divided into two groups of four series each; and from the first of these
