From this follow immediately with (IV) and the reduction factors 
of § 4 the virial coefficients in the development of series (LI), which 
gives the value calculated for the pv4 observed by AMAGAT. 
The following tables show the deviations between observation and 
calculation for all the observations. If we examine them, it appears 
that the deviations must be chiefly attributed to the difference of 
the substances which we have combined, and might also be partly 
due to the uncertainty of the critical data.
