TABLE XXI. FOR CALCULATING SOLIDS NOT FAT FROM FAT 

 AND SPECIFIC GRAVITY. 



* The solids not fat are correct for the middle line of specific gravity ; 

 if the specific gravity falls in the top line subtract 1 from the solids not 

 fat ; thus 26-0 specific gravity and 3-0 per cent, fat give 7-25 per cent, 

 solids not fat ; if the specific gravity falls in the bottom line, add 1 to the 

 solids not fat ; thus 34-0 specific gravity and 3-0 per cent, fat give 9-25 per 

 cent, solids not fat. 



f The last line indicates where the change of solids not fat takes place ; 

 in a column with 0-2 at the bottom use the column itself for the percentage 

 of fat given, and 0-05, 0-10, and 0-15 above, but use the figure immediately 

 below for 0-2 above ; thus 30-0 specific gravity and 3-1 per cent, fat give 

 8 '25 per cent, solids not fat, but 30-0 specific gravity and 3-2 per cent, fat 

 give 8-30 per cent, solids not fat; in a column with 0-1 at the bottom, 

 use the column itself for the percentage of fat given and 0-05 above, but 

 change to the figure immediately below for 0-1 or more above ; thus 30*5 

 specific gravity and 3-30 per cent, fat give 8-40 per cent, solids not fat, but 

 30-5 specific gravity and 3-40 per cent, fat give 8-45 per cent, solids not fat.
