lectly free from Vapor. 



*^* The above numbers are obtained from Dr. Dalton's experiments 

 which give an average of j^j part, or -00207 for the expansion b)^ each 

 degree of Fahrenheit. Gay Lussac found it to be equal to ^|^ part, or 

 •002083 for each degree of Fahrenheit ; and that the same law extends 

 to condensable vapors when excluded from contact of the liqnids which 

 produce them.
