COBALT CHLORIDE. 



153 



In tables 74 to 76, containing viscosity data, the values for pure water, 

 at and 25, taken from the work of Thorpe and Rodger, are used, and all 

 the other values are referred to them ; t\ is the viscosity, while $, which rep- 

 resents fluidity, is obtained from the expression 



The density of the liquid in question at and 25 was compared with the 

 density of water at and 25, respectively. The density of water at 

 and 25 was taken from data given in Landolt and Bernstein's tables. 



The values of 77 and </> for the solvents methyl alcohol, ethyl alcohol, acetone, 

 and mixtures of these, are taken from the work of Jones and Bingham.
