When the number expressing the specific gravity found by analysis falls between 

 the numbers given in the above table, the exact equivalent in degrees Brix or Baume 

 is found by a simple calculation. 



Example. — The pycnometer shows the specific gravity of a certain sirup to be 

 1.20909. The table shows that the corresponding degree Brix is between 45.0 and 

 46.0. Subtracting the specific gravity of a solution of 45° Brix from the correspond- 

 ing figure for 46°, we have (expressing the specific gravities as whole numbers) 

 121,100 — 120,565 = 535, the difference in specific gravity for 1° Brix at this point 

 in the table. Subtracting the specific gravity corresponding to 45° from the spe- 



344 

 cific gravity found by analysis, we have 120,909 - 120,565 = 344; -— = 0.64, the frac- 



OoO 



tion of 1° Brix more than 45°. The degree Brix, corresponding to a sp. gr. of 1.20909, 

 is therefore 45.64.
