Observations on the Table of Sugar. 



The experiments of Messrs. Playfair and Joule corroborate 

 those of Dr. Ure, though made in a different manner and for a 

 different purpose. According to the experiments of both 

 parties, when sugar is dissolved in water so as to form a strong 

 solution, there is an expansion of volume. The volume of the 

 solution exceeds the volume of the two ingredients. When 

 more water is added condensation ensues, and is carried by 

 continued dilution to such an extent, that, according to the 

 experiments of Messrs. Playfair and Joule, in a solution of 

 sp. gr. 1*0035, the condensation effected by 1 test atom of 

 sugar is equal to 16*30 septems, or more than the measure 

 of an atom of water. 



The volume of 1 test atom of water being 16*07 septems, 

 that of 11 test atoms is 176*77 septems, and that of 12 test 

 atoms is 1 92*84 septems. The atomic measure of anhydrous
