which appeared some years ago, Cayenne linaloe oil was stated to 

 differ from the Mexican variety by the absence of methyl heptenone, 

 terpineol and geraniol. Having had occasion to examine Cayenne 

 linaloe oil ourselves, we have ascertained that Theulier's observation 

 is incorrect, inasmuch as we succeeded in establishing beyond all 

 doubt the presence in the oil of both d-terpineol (m. p. 35 ) and of 

 geraniol. Judging by the odour of the first runnings, however, it must 

 be admitted that methyl heptenone appeared to be absent. We found 

 the oil under examination to possess the following constants : d^o 0,8786, 

 «x> — 12 20/, sap. no. 4,2 acid no. about 1, soluble in 2 vols, of 70 per 

 cent alcohol. 



The oil fractionated by us had been saponified with alcoholic 

 potash from which the alcohol had been removed by distillation by 

 water vapour. Apart from a small quantity of first runnings, the bulk 

 of the oil passed over between 68 and 95 (6 to 7 mm. press.). 

 The fractions with b. p. 68 to 75 containing the linalool were left 

 out of account. For the determination of the terpineol we used a 

 portion of the oil which, after repeated fractionation, passed over 

 between 83 and 88° (7 mm. press.). The mere odour of this showed 

 the presence of terpineol. When inoculated the cooled fraction 

 solidified completely. The crystals, pressed out on porous tiles, 

 melted at 35 and, in their re-melted state, had an optical rotation 

 «d -{- 1 8° 6', which proved them to consist of d-terpineol. The phenyl- 

 urethane obtained from them after treatment with carbanile had, as 

 was expected, the m. p. 1 1 1 to 1 1 2 °. In order to prove the presence 

 of geraniol, a fraction with a b. p. of from 90 to 93 (6 m. m. press.) 

 was heated for several hours on the water bath in benzene solution 

 with phthalic anhydride. From the sodium salt solution of the resulting 

 phthalic ester acid there separated upon saponification and simultaneous 

 steam distillation, an oil with an unmistakable geraniol-like odour. This 

 passed over at from 91 to 92 (5 mm. pressure) and at 22"] to 2 2 8° 

 under atmospheric pressure and was recognized as geraniol by its 

 specific gravity (di 5 o 0,8820), its optical inactivity, and its odour, as 

 well as by the diphenyl urethane (m. p. 80 to 81,5°). The terpineol 

 content of the oil did not exceed 5 °/ , nor the geraniol content i°/ . 



Oil of Lovage root, own distillation. After a long interval 

 we have this year again distilled two parcels of oil of lovage from 

 different highly developed roots, one parcel being obtained from fresh 

 Thuringian root of the second year's growth and another from fresh 

 root of the first season, of our own growth. In spite of the difference 

 in the age of the material used, the oils show only unimportant differ- 

 ences in their properties, and a mere enumeration of their constants 

 will therefore be sufficient: —
