306, 307] Dependence of Viscosity on Density

At the same time, it must be mentioned that the experimental con- 

 firmation of this law is by no means complete. Meyer* gives a detailed 

 account of experimental work which has been performed to test this law. 

 He comes to the conclusion that the divergencies from the law exhibited by 

 experimental results are not so great as to be inconsistent with the truth of 

 the law, at any rate within the limits of pressure from 1 to ^ atmosphere. 

 That the divergencies are very considerable outside these limits will be shewn 

 by the two following tables, taken from Weinstein'f*.

II. Experiments at pressures greater than one atmosphere
