BETWEEN THE VISCOSITY OF LIQUIDS AND THEIR CHEMICAL NATURE. 
95 
The following tables contain the coefficients of viscosity read off from the working 
curves at intervals of 10° Similar values for the new samples of isopentane and 
ethyl benzene have already been given on pp. 89 and 91 respectively.
