 EXPERIMENTS OF LAVOISIER AND LAPLACE. 



V. TABLE OF THE EXPANSIONS OF LIQUIDS. 



The expansions in this table were determined by Mr. D alt on. They are equal 

 to what would be produced by an elevation of temperature from the freezing to 

 the boiling point of water ; the volume at the former being 1.
