A Table of Specific Gravities. 



Principally from Davics and Lavoisier. Davies's table is 

 compiled with great diligence from many different authors ; 

 Lavoisier's is chiefly extracted from Brisson ; it is carried to 

 four places of decimals, but little dependence can be placed 

 on the last.
