Since two observations are not sufficient to give the curve, a set of relative density 
determinations was made in the usual way. The results are shown in Table XIV.

The reciprocals of the numbers in the third column are proportional to the specific 
gravity of the vapour. These reciprocals with the scale suitably altered so as to 
coincide as nearly as possible with the values in Table XV. are marked by circles on 
the curve of fig. 5. The two values of the absolute density are marked by crosses. 
The curve was employed in the usual way for finding the numbers in the fifth and 
sixth columns of Table XVII.
