During these experiments the tube was jacketed with the vapour of boiling 
mercury ; the readings are given in arithmetical order, but were taken sometimes 
with rising, sometimes with falling pressure. 
§ 49. The results of all these experiments are shown in Plate 1 ; where it will be 
seen that the curve representing the temperatures of volatilization under different
