42 SPECIFIC GRAVITY OF LIQUIDS. 



both of them are thus obtained. For instance, suppose 

 the flask to weigh empty GO 81 ", filled with water 130^, 

 filled with a strong solution of common salt 144^; the 

 bottle holds then 130 - 60 = 70^ of water, and 

 144 60 = 84^ of the solution, which has therefore a 



spec. gr. of |^ = 1-2. 



In Table I., at the end of this book, will be found the 

 Specific Gravities of some of the most important sub- 

 stances.
