thing to strike one on looking at the diagram is that the effects are 

 nearly constant over the entire range ; the compressibility does not 

 change markedly, nor does the dilatation, and the lines bounding the

domain liquid-solid are nearly parallel. It is evident, therefore, that 

 any reversal of the ordinary effects or the appearance of critical points 

 must be far beyond the reach of the diagram. The diagram is com- 

 petent to show only the initial trend of the various effects. 



For the liquid state the results are the same in general as those with
