Summary

  1. 1.

    The rotatory power of thedextro- andloevo- forms of xylidinomethylenecamphors (m andp) are identical, and obey thesimple dispersion law of Drude.

     
  2. 2.

    The substitution of a methyl group for an atom of hydrogen in the phenyl group of anilinomethylenecamphor lowers its rotatory power. The introduction of a second methyl group as in the xylidinomethylenecamphors generally lowers the rotation still further, owing to thepolar effect of the first methyl group being reinforced by that of the second like group.
