TABLE VII. Giving the Boiling Temperature of Pure Water, 

 and the Temperature of a Boiling Mixture of Steam and 

 Chloride of Sodium, for Barometric Pressures between 550 

 and 770 Millimetres. 



for every tenth millimetre from 770 to 550 mm., and the 

 corresponding temperature of saturated steam (7"); under 

 (/), the temperature of a boiling mixture of steam and NaCl 

 under the barometric pressure (/>); under /(= T345/ 1 ), the 

 calculated tension of saturated steam of temperature /; and 

 under t-T, the excess of boiling-point of saturated NaCl 

 solution above that of pure water under the given pressure. 

 This table gives figures which agree closely with the results
