The oil, after having been washed with ‘normal Na.CO; solution and dried with 
Biyaraus sodium sulphate, smelled strongly of citral; doo 0.845 and 0.860; <p200

ai Be from 48 to 115°. The presence of a-pinene ‘could be proved in the fractions 
boiling between 48 and 52° and between 52 and 70°. The nitrosochloride melted 
bes een 102 and 103°, the hydrochloride at 132°. The latter fraction also contained 
-limonene, b.p. 175°; apo +38°; tetrabromide, m.p. 104°. This fraction did not 
yi rield any semicarbazone with semicarbazide-HCl and sodium acetate. 
3 The fraction boiling at from 70 to 85° (12 mm.) contained linalool in addition to 
limonene. The linalool was characterized | by shaking it with 5 per cent. sulphuric 
‘acid, when terpene hydrate formed (m.p. 116°). The oxidation of the linalool to 
citral was impossible in this connection, since > citral was in the Heese fraction 
in large quantity. ; 
F _ Zoller proved the presence of cial in the fractions boiling between 85. and 115°; 
the semicarbazide melted at 165°. 
As the fraction boiling between 100 and 115° ‘epuld not contain any linalool, 
judging by its boiling point, but on being shaken. with 5 per cent. Sulphuric acid 
deposited terpene hydrate, Zoller assumed that geraniol was present. It may be 
expected that both linalyl and geranyl acetate are present too.

oil and 0.166 percent. of floral wax. Hnflewrage did not lead to any result. The oil

fo Blowing constituents were ascertained: 6 per cent. linalool, 6 per cent. linalyl acetate, 
1.6 per cent. benzyl alcohol, 6 per cent. benzyl acetate, 10 percent. indole and methyl 
‘anthranilate*). The higher-boiling fractions contained a diterpene or a sesquiterpene

g Kauri copal Oil. On dry distillation or with steam, kauri copal Groin Dammara

Ne ertheless, we would mention that, according to an article published in trade- 
journals, progress is made in obtaining simultaneously from kauri trees crude oil, 
acetic acid, ammonia, pitch and “spirit-gum“, a quickly drying adhesive substance,
