OSMOTIC PRESSURE OF AQUEOUS SOLUTIONS. 



be concluded at this point. But, since the results of the measurements 

 foreshadow much that was afterwards established by means of greater 

 precision, it has been thought worth while to arrange them in Tables 

 37 to 39, with a view to ascertaining what general conclusions they 

 suggest with reference to the osmotic pressure of cane-sugar solutions. 

 Section A of Table 37 gives all of the observed osmotic pressures 

 of Series I to VIII, except those of the 0.05 and 0.25 concentrations of 

 Series I; these concentrations are omitted, as they were abandoned 

 after the first series. Section B gives the observed osmotic pressures 

 of Section A, corrected for dilution proportional to the observed losses 

 in rotation. Section C gives, for each experiment, the ratio of the cor- 

 rected osmotic pressure to the calculated gas pressure of the solute.
