0:837 at 18°; a strong disagreeable odour, like that of the 
plant ; a slightly bitter aromatic taste; boils at 228°—230°, 
_ and solidifies between + 1° and 2°, to shining crystalline 
lamin, resembling those obtained from Anise oil. The chief 
volatile constituents of rue are methyl-nonylketone, and a hydro- 
carbon. The ketone, separable by alkaline bisulphites, was 
formerly regarded according to the investigations of Gerhardt 
_ and of Cahours, as capric or rutic aldehyde, C1? H*° O, But 
Greville Williams has shown that the crude oil contains two 
such compounds, viz., C1! H*? O and C!* H?* O, the latter in 
comparatively small quantity ; and this result has been con- 
firmed by Harbordt. The portion of rue oil, which does not 
combine with alkaline bisulphites, is separable into a more 
volatile portion, having the composition of Turpentine oil, 
and a less volatile portion, which appears to be isomeric 
with Borneol, but boils at a lower temperature. For a fuller 
account of the chemistry of Rue, see Watt's Dict. of Chem.,
