“ Numerous experiments 
were made to fix the critical point of mixture and 
the pressure when liquid a little below that point disappears on augmenting 
pressure. 
. . . On augmenting pressure and then suddenly diminishing it, 
no 
cloud 
appeared at 21 
°-2, 20°"8, 20° -57 (two experiments), 20° 39. At 20*35 
cloud appeared ; also at 20‘24 and 20T3. The limit was therefore between 
20' 
’•35 and 20°-39.”

On allowing it to stand there changed as follows : the whole volume remained 
same, but liquid gradually passed into [the gaseous] space ; on allowing the 
whole to stand for two hours the liquid surface at last disappeared ; the 
liquid having gradually diminished and the volume of whole increased to 
18-0, the pressure and temperature were quite steady.
