a derivative of linalol, it was endeavoured to obtain in the above 
manner a phenyl urethane from 1-linalol. For this purpose, commercial 
linalol (produced from linaloe oil) was submitted to careful fractional 
distillation, at first under reduced, and subsequently at ordinary pressure. 
The principal fraction (spec, gravity 0,8715, optical rotation — 14° 7') 
boiling at 9 mm pressure at 81,5° to 82°, at ordinary pressure at 
196° to 199^, yielded, as a matter of fact, the phenyl urethane whose 
melting point in this instance was found at 65° to 66*"^. An analysis 
gave figures which agree well with those calculated for a linalyl 
phenyl urethane. 
0,1589 g of the substance yielded 0,1218 g HgO and 0,4365 CO2. 
The body crystallises from dilute alcohol in well-defined prisms, 
from ether and petroleum ether in long needles. It dissolves readily 
in ether, alcohol, benzene, petroleum ether, chloroform, acetic ether, 
methyl alcohol, and glacial acetic acid, but is almost insoluble in water. 
The best medium for crystallisation is therefore dilute alcohol. 
According to the observations which we have up to now made 
the phenyl urethane (assuming that it actually proves to be a deriva- 
tive of linalol) might be found very suitable for the rapid and certain 
detection of this alcohol. At any rate, we have been able to isolate the 
phenyl urethane of the melting point 65° with facility from a portion 
of 1,5 grams of a fraction containing linalol. Subsequent tests with 
d-linalol from coriander oil (specific gravity 0,8687, optical rotation 
-[- 12° 51') have produced the same derivative of the identical melting 
point. We shall not fail to follow up this interesting discovery, and 
therefore reserve this body for further work. 
It has not yet been possible to obtain in the above manner a 
solid phenyl urethane from geraniol. Geraniol reacts with phenyl 
isocyanate with considerable evolution of heat. We mixed equal 
molecules of geraniol and phenyl isocyanate whilst cooling with ice, 
and left the mixture standing for 7 days at ordinary temperature. 
After 3 days a solid product began to separate out, which was clearly 
diphenyl urea, and which had certainly been formed by the geraniol 
splitting off water. As the final product of the reaction, a bright- 
yellow, viscid oil was obtained, which up to now has shown no ten- 
dency to crystallise. This also will be submitted to further examination. 
We also succeeded in detecting d-terpineol in petitgrain oil, like 
in neroli oil. This body, which may not be without importance for 
the odour of petitgrain oil, was isolated from a fraction boiling under
