Lines of equal volume, or isochors, were then mapped from 

 these results, pressures and temperatures being ordinates and 



abscissae. The values 



of % or b, 



were then read for each 



separate volume and smoothed, as before described. The fol- 

 lowing Table shows the read values, and the values after 

 smoothing. The values of a are also given, calculated by 

 the equation a = bi—p, from the results shown on the previous 

 table ; the means of all the individual results for each volume 

 are stated. Table IL
