TABLE 129.-Refractive index of levulose solutions

[All data computed from weights in air with brass weights. Immersion readings are referable solely to the scale of arbitrary units proposed by Pulfrich (Z. angew. Chem., p. 1186, 1899). According to this scale, 14.5=1.33300; 50.0= 1.34650, and 100.0-1.36464]

TABLE 130.-Viscosity, in centipoises, of sucrose solutions

[Recommended for use in the calibration of viscometers. These values are based upon measurements made at the National Bureau of Standards on solutions containing 20, 30, 40, 50, 60, 65, 70, and 75 percent of sucrose by weight in vacuo, using the value 1.0050 centipoises for water at 20° C, and are estimated to be accurate to about 0.1 percent]
