TABLE IV. 



TABLE of the Specific Gravity and Expansion of "Water at different 



Temperatures. 



*^* In the above Table the expansions are calculated by Dr. Young's 

 formula, 22 /'^ (1 — -002/) in ten millionths. The diminution of specific 

 gravity is calculated by this equation: •0000022/-^ — •00000000472/3. 

 In both equations, / represents the number of degrees above or belo-w 

 39^ of Fahrenheit. The absolute weight of a cubic inch of water, at 

 any temperature, may be found by multiplying the weight of a cubic 

 inch at 39^, by the specific gravity at the required temperature.
