which will be undertaken shortly, may yield additional supports of the 
above view !). 
The reduetion leads to nonerystalline substances if the condi- 
tions described above are not fulfilled. If for instance more acetie 
acid is used and the solution poured into water a yellow precipi- 
tate is formed which is easily soluble in acetie acid and which 
could not be erystallized from any of the usually applied organic 
solvents. 
In our next communication we hope to be able to add to the 
knowledge of the reduction product of bixin and to deseribe our 
studies concerning the action of phenylhydrazine and of water or 
alcohol at high temperatures under pressure, and also the hydro- 
earbons produced by destilling bixin with zinc dust. 
1) It is also worthy of notice that under certain, hitherto not clearly ascer- 
tained conditions, bixin yields under the influence of reducing agents a substance 
possessing the scent of violets. According to Arnaud and other authors carotene 
when heated also emits the scent of violets.
