and a second a melting at 221° C. which has probably the compo- 
sition CHO... The first of these acids throws some light on the 
position of the hydroxyl group in the molecule of turmerol. 
Professor Jackson and his assistant have also studied the action

carefully and its composition indicates that the intermediate pro-
