drews could be put to a crucial test. By compressing hydrogen 

 over various liquids in which it is insoluble, I was enabled to 

 carry the above proposition into effect, and after several hundreds 

 of experiments, detailed in a paper read before the Royal Society, 



continuous than are the solid and liquid slates, but arc separated 

 by an isothermal passing through the critical point. In fact by 

 Latour's or Andrews's method, where the liquid was in contact 



passage at any pressure, and it takes place as suddenly at -J no 



- pressure as at the critical pressure'. Thus the crit icai 

 point is the termination of an isothermal line, which is the limit 

 of the liquid state. 



As to the other mode employed by Andrews — namely, pressure 



it did the continuity of solid and liquid states could easily be 

 proven. In fact, the irregularities observed by Andrews in the 

 vicinity of the critical point rather lend support to the views
