like properties. The curve for 310° intersects these at high 

 pressure. This, however, was suggested in §28, since above 

 the critical temperature the mean equation (2), is not appli- 

 cable. The chief result of the table is given in the supple- 

 ment, for v^= 028^80= 1. It appears that d and p as far as 185°

Similar remarks apply for ether, where conformably with the 

 lower critical point, the high temperature discrepancy is more 

 pronounced. The rate of variation of d and p for / y ( 9 J 3=^28,ioo = l
