3IO TABLES 3ffO, 381. ROTATION OF PLPIME OF POLARIZED LIGHT. 



TABLE 380. Tartaric Acid; Camphor; Santonin; Santonio Acid; Cane Sugar. 



A few examples are here given showing the effect of wave-length on the rotation of the plane of polarization. The 

 rotations are for a thickness of one decimeter of the solution. The examples are quoted frc 



stein's 



'Phys. Chem. Tab." The following symbols are used : 



/= number grams of the active substance in 100 grams of the solution. 

 c= solvent 



9=. active " " cubic centimeter " 



Right-handed rotation is marked +, left-handed .

TABLE 381. Sodium Chlorate; Quartz. 



* The paper is quoted from a paper by Ketteler in " Wied. Ann." vol. 21, p. 444. The wave-lengths are for 

 the Frauiiholer lines, Angstrom's values for the ultra violet sun, and Cornu's values for the cadmium lines.
