"E[rnst]. Schulze (Berl. Ber., 12, 249) has determined the specific rotation of isocholesterine (found by the author, associated with cholesterine, in the fat from sheep’s wool). This substance is dextro-rotatory, whereas cholesterine is laevo-rotatory. An etherial solution of isocholesterine, containing 6.453 gms in 100 cc, showed in the 200 mm tube of a Soleil-Ventzke polariscope, a rotation of 22°; a solution of half the strength rotated 11.25°. A solution of another preparation, containing 7.344 gms in 100 cc, showed a rotation of 25.5°. From these data, the author deduces for isocholesterine the specific rotation [a]_b = + 60°."
