ation from hot water, was sufficiently pure for analysis. The determin- 
ation of sih'er made with it gave the following figures: 
0,2031 gram of the substance yielded on heating 0,1310 gram Ag, 
The value found therefore agrees with that calculated for silver 
acetate. The alcohol obtained from the saponification distilled at 
II to 12 mm pressure at 1 11 to 112°. Its specific gravity was 
0,8842, its optical rotation -|- 0° 18'. After purification by the calcium 
chloride compound, the specific gravity was 0,8830, the optical rotation 
almost 0°. The diphenyl urethane of this alcohol melted at 82^. 
The presence of free geraniol was also proved by the diphenyl ure- 
thane. For this purpose a fraction was used which boiled at 90 to 
96°, at 6 mm pressure. 
We have also by the odour established the presence of a basic 
body in petitgrain oil. It can be extracted from the fractions of the 
boiling point of linalol, by means of dilute sulphuric acid, and it 
appears to have a special influence on the odour of petitgrain oil. 
It follows from the foregoing, that we have detected in Paraguay 
petitgrain oil: furfurol, l-pinene(?), 1-camphene (?) dipentene, an alcohol 
QoHjgO (1-linalol), d-terpineol (melting point 35^), geraniol, geranyl 
acetate, and also traces of a basic body. 
Pine-needle Oils. The fine distillates from the needles of 
Fz;nis Piimilio and Abies pectinata could in the spring only be obtained 
with difficulty in sufficient quantities, and that at higher prices, owing 
to the unfavourable weather prevailing in the Alps. On the other 
hand, the distillate from the cones of the last-named species was 
abundant, and could be purchased at favourable prices. The very 
advantageous oil of the Siberian fir, which is now distilled in Russia 
on a large scale and of faultless quality, has recently become very 
popular. It is also eminently suitable for pine-odour soaps, for which 
purpose it is generally diluted with a small quantity of lavender oil,, 
so as to soften the pungent odour. This oil can be obtained in any 
quantity. 
Oil of Pseudocymopterus anisatus. Brandel^) has produced 
the oil of Pseudocymopterus anisatus Gray (C. and R.) which grows in 
the wild state in the Western United States of America, in a yield 
of 4 grams from the whole plant. 
The odour of the fruit and of the oil resembles that of anise in 
a marked degree; the specific gravity 0,978 (20° C) also closely agrees 
Found: 
Ag= 64,50 per cent. 
Calculated for C2H3 02Ag: 
64,67 per cent.
