THE VISCOSITY OF WATER. 



35 



The table contains also the kinetic energy correction in 

 each case. The values are reduced to even temperatures 

 by means of the formulae to be given later in the paper. 

 These formulae reproduce the observed values with remark- 

 able closeness, and so the above method of reduction is 

 justified.
