If the difference of temperature for example be 8 degrees, 

 and the mean temperature 172°, then, for water, 8 x '00035 = 

 ■0028 is the expansion of water by 8 degrees of heat, and 

 8 x '00038= 00304 is the expansion for a saturated solution 

 of salt. 



10. The friction of fluids, and particularly the effect of 

 change of temperature, has been investigated only in a very 

 partial manner, the following Table is collected from the 

 experiments of Dubuat.^
