to attach the latter, hydrobromic acid is split off. When sulphuric acid 
is allowed to act on cineolene, a-2-cymene sulphoacid is formed, which 
was identified by its barium salt. Molle believes that the following

Lavender Oil. The purchases during the last season were a 
source of great difficulty, as there were more buyers than sellers. It 
is also due to this fact that the producers were able to carry through 
their exaggerated demands for the first parcels, for the total result of 
the crop did not justify the high prices. At the present time the bulk 
of the production of finest oils is lying in the cellars of middlemen, 
and only lately some fine parcels passed from the producers into 
our possession, which enables us to reduce somewhat our prices. On 
the other hand, some large parcels of medium qualities with 25^/^ 
ester and a strong suspicion of spike oil are on the market, which 
may be sold below the value if an opportunity arises. 
In continuation of our previously ^) published work on French 
lavender oil, we wish to mention that the acid obtained by sapon- 
ification from the portions boiling at 155° to 172°, has been found 
to be butyric acid 2).

The alcohol contained in the neutral saponification-products had 
the distinct odour of isoamyl alcohol, but, unfortunately, could not 
be identified further. 
Umney^) calls attention to the fact that some English lavender 
oils met with in commerce do not answer the requirements of the 
British Pharmacopoeia of 1898. He believes that the cause of this 
must be found in the method of manufacture, as for example in 
Mitcham it is usual to collect the lavender distillates in two portions, 
whilst experience has shown that the last portions of the distillate do 
not possess such a pleasant odour as the first. For this reason, many
