Thus the locus is convex towards the axis of pv, and there 

 is a mini-max point ; in fact the existence of such a point 

 was already pointed out by M. Amagat, for the case of pure 

 carbonic acid. Fig. 3.

The parametric values of volumes and pressures for iso- 

 metrics and isopiestics respectively are so chosen that we 

 can easily compare the results with those for pure carbonic 

 acid, as given by the most recent experiments of M. Amagat* 

 (see fig. 3).
