into the quinone or the hydroquinone respectively. In this manner 
two different bodies were obtained. Now, in order to solve the ques- 
tion of the constitution of the above-named phenol, it only required 
the following consideration: assuming that the phenol were a (i)-propyl- 
( 2, 3)-(Jimethoxy-(5)-oxy-benzene, and the O H -group therefore in 1,5 po- 
sition towards the propyl-group, it would follow that from the (i)-propyl- 
(2, 3)-dimethoxy-(5)-propyloxybenzene and -(5)-ethoxy benzene, when 
treated with nitric acid, one and the same quinone, (i)-propyl-(3)- 
methoxy- (2, 5)-quinone were formed, for the quinone - formation is 
brought about with elimination of both alkyl- groups occurring in the 
para-position. Assuming, on the other hand, that the phenol in quest- 
ion were a (i)-propyl - (2, 5) - dimethoxy- (3) -oxy benzene, it would 
follow that from the (i) -propyl -(2, 5) -dimethoxy -(3)- ethoxy benzene 
and the (3) -propyloxy benzene two different quinones, or hydro- 
quinones respectively were formed, viz. (i ) -propyl- (3) -ethoxy- (2, 5)- 
quinone, and (i) -propyl -(3) -propyloxy- (2, 5) -quinone. Now, as the 
latter case agreed with the actual facts, it was thereby proved that 
the phenol is a (i)-propyl-(2, 5)-dimethoxy-(3)-oxy benzene. Apiol is 
consequently a (i)-allyl-(2, 5 ) -dimethoxy- (3, 4) -methyl enedioxy benzene.

Aubepine (Anisic aldehyde). This body is obtained as a 
by-product, and its value is consequently problematical. Although our 
quotations have been much reduced, the use of this article remains 
to a certain degree limited, as the perfume-compositions for which it 
is employed as a base do not belong to the most popular articles 
of perfumery.
