By means of the following table, the manufacturer may be able to 

 determine the percentage of total solicis in his juice or syrup, by sim. 

 ply taking the specific gravity at any temperature not over 100° C. or 

 212° F. For example, a sample of syrup, at a temperature of 80° C, 

 had a specific gravity of 1.2862 — that syrup contains Qo per cent of 

 total solids ; and at 15° C. this sample would have a density of 1.3211. 

 For temperatures and percentages between those tabulated, it will be 

 easy to make the necessarv calculatious.
