R. HOSKING. 



A single formula which represents the results over the 

 whole range of temperatures is 



% 



9*185 



1-6232 



(5) 



(46*694 4- t) 



but the agreement between the observed values and those 

 derived by this formula is not so good. 



The following table gives the complete set of my values 

 for the absolute viscosity of water, and also the values of 

 Thorpe and Rodger as re-determined by Knibbs. It also 

 contains the values computed by the formulae already 

 mentioned. I consider that my values are correct as far 

 as the last figure given in each case.
