The saponification value and the ester. value after acetylation were established for “ 
various oils. Both numbers were. rather low. The authors further determined the content — 
of the oils in dill apiole. The presence of this body can be proved in the fractions — | 
distilling above 160° (30 mm.) by converting it into the dibromide, melting at 110°: The- 
dill apiole content of the different oils varies considerably, as is show in the follow-—

The content of dill apiole was judged by the quantities of high-boiling constituents. f o 
All the oils examined contained thymol methyl ether, the presence of which is proved 
as follows: 1 cc, of oil, together with 2 cc. of hydrobromic acid (d 1.48) and 10 cc. of er 
glacial acetic acid, is heated for 6 hours under a reflux. condenser. Then, 20 cc. of water 
are added, the mixture is neutralized and afterwards extracted with ether.-On evaporating " 
the latter, crystalline thymol remains. The presence of the methyl alcohol, split off in 
this process, has been proved by the authors through transforming it into as Le 
iodide (digo 2.23). Ade 
The authors have not been able, so far, to determine with certainty whether d-pinene — 
occurs in the oil from the Mediterranean coast; the other oils contain this hydrocarbon. — 
Dipentene does not occur in the oil of Crithmum maritimum, Delépines former indi- — 
cation being due to a-confusion with crithmene, the hydrocarbon which is characteristic i ‘ 
for Crithnum maritimum oils. According to Francesconi and Sernagiotto, crithmene _ 
yields the following derivatives: «-nitrosochloride (m.p. 101 to 102°), 8-nitrosochloride Ce 
(m.p- 103 to 104°), nitrol piperinide (m.p. 138°), nitrol benzylamine (m. p. 103 to 104°), 
nitrosite (m.p. 89 to 90°), nitrosate (m. p. 104°), dihydrochloride (m. p. 52°). Delépine i 
and de Belsunce have been able to detect neither the nitrosite nor the nitrosate; 
they have found the m.p. of 110 for the nitrosochloride and that of 148° ae the nitrol 
piperidide. Bike 
8-phellandrene, present in the Italian variety, was not to be ROA in the French 
oil of Crithnum maritimum. | fig gas ae
