Optical Rotatiizg Power o f Cavzplzov 205 T h e foregoing measurements are recorded in the order they were made. By extending the curves expressing the relation between specific.rotation and concentration, the following values are obtained for the specific rotation of pure canlphor : -At 0' [a]== 53.1 2 0 ' [a]"= 54.8 40' [a] = 56.4. Solvent -Nitrogeiz Peroxide (NsO,). -Liquid nitrogen peroxide dissolves camphor very readily. A solutioti containing 40 percent camphor was prepared, but it does
