The higher brominated products, di- and tribromisoeugenol dibromide, 
agree with the monobromo derivative with regard to their phenol or 
pseudo-phenol character. 
Aubepine (Anisic aldehyde). This preparation, the basis of 
the hawthorn-perfume, is obtained as a by-product in the manufacture 
of coumarin, and is now so low in price, that the consumption has 
increased considerably. At the same time, it remains an article of 
subordinate importance, and one of those perfumes which must be 
used with discretion so as not to appear obtrusive. 
We must point out that anisic aldehyde, when exposed to the 
air, oxidises readily into anisic acid, and should therefore be kept in 
well-closed bottles, if possible filled completely. 
Benzyl acetate. This body, which we were the first to intro- 
duce into commerce, has recently gained in interest, since we succeeded 
in producing it at a very moderate price. It forms a constituent of 
natural and artificial oils of jasmine and ylang ylang, and on account 
of its ready solubility is very suitable for the manufacture of cheap 
extract and Eau de Cologne preparations with a low alcohol-content. 
Our benzyl acetate is absolutely free from chlorine. 
Borneol (Borneo camphor). In the manufacture of this body 
a decided advance can also be recorded. In consequence of this, 
the cutting of the price continues vigorously, and the end will be that 
nobody will be any the better for it. The same thing happens with 
all articles whose importance is overestimated. 
Citral. The criterion for the value of this' article is the greater 
or smaller degree of purity of the product. It is well known that 
citral was discovered and named by us in 1888. Although its use- 
fulness was at first questioned and deprecated, it is now universally 
employed for the manufacture of concentrated lemo];i oils, essences 
and extracts, and may be called practically indispensable.
