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 / 2 (1 -002/) in ten millionths. The diminution of specific 

 gravity is calculated by this equation: -0000022/ 2 -00000000472/3. 

 In both equations, / represents the number of degrees above or below 

 39 of Fahrenheit. The absolute height 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.
