thus obtained gave thoroughly satisfactory results. The results of all 
these calculations viz. the coefficients 6,, 6,, 6,,6,, 6,,c,,¢, etc, of the 
equation VII. A.3., the virial coefficients obtained from these, and 
finally, the comparison of VII. A.3. with the experimental data 
are given in the following tables. 
The figures italicised in the tables are those which have been 
taken from VII. I.
