In Table V. we have the interpolated results for NaCl. 



In Table VI. the final mean values only, for sugar solutions. 

 The sample of sugar used was supplied by Professor Masson. 

 The densities of the solutions at 17 c, 5 C. are here given: —

And in Table VII. the interpolated values for sugar solutious 

 are reproduced. 



For the purposes of interpolation the results were plotted on 

 a suitably large scale. The results are herewith shown plotted 

 on a smaller scale in figs. 1 & 2 (pp. 280, 281). A value of the 

 viscosity at ordinary temperatures was sometimes obtained 

 after the liquid had been heated above 90°, cooled down again, 

 and allowed to remain, in some cases 24 and in others 

 36 hours, in the ojischrometer. These observations are indi- 

 cated in a different way in tne accompanying curves, to 

 the ordinary observations.
