582 DR. J. W. CAPSTICK ON THE RATIO OF THE 
Fig. 8. 






Table XXIV. gives the results of the vapour-density determinations. The numbers 
in the fourth column are taken from the curve in fig. 8, and when multiplied by the 
corresponding numbers in the third column should give a constant, if the two series 
of experiments are consistent. The products are shown in the last column.

The mean of the numbers in the last colunin of this tabie divided by the ordinate 
of the curve in fig. 8 for a given pressure, gives the best value of the vapour-density 
for that pressure. The fifth column of the table below was calculated in this way.
