The value of dj, is that value of 6, for which v has the same 
value as 6, and the pressure is therefore infinitely high. This value 
of Vim = Dim is the smallest volume in which the substance can 
still be in thermal motion, but it is still appreciably greater than the 
joint volume, in which the molecules, when they were stationary, 
could be contained. The reduced equation of state which hag the 
form

increasing deviation, however, as the density approaches the limiting 
density.

great than might be feared, but yet not negligible, and manifests 
itself in the different directions of the rectilinear diameter *).
