of 0.9789 at 15° C., an optical rotation of —0° 49', a congealing point 
of +17°, and soluble in 8.5 parts of 80 per cent alcohol. Russian 
seeds yield a much larger percentage of oil, with a slightly higher 
specific gravity and lower congealing point. — Pharm. Rev., Mil- 
waukee, 1906, v. 24, p. 113. 
Nelson, Burt E., figures and describes the microscopical appear- 
ance of jmwdered star anise. — Merck's Rep., N. Y., 1906, v. 15, p. 322. 
Schimmel & Co. assert that the solidifying point of pure oil of star 
anise lies above +14° and that solidification must, if necessary, be 
started by inoculation with a small crystal of anetliol. Star anise 
oil dissolves in from 1.5 to 3 volumes of 90 per cent alcohol. — Semi- 
Ann. Rep. Schimmel & Co., 1906, Oct.-Nov., p. 95. 
Eberhardt, Ph., reports a new method for the extraction of oil of 
anise and makes a recommendation as to the production of oil which 
he thinks will greatly increase the annual production. — Compt. rend. 
Acad, des Sc., Par., 1906, v. 142, pp. 407, 408. 
(See also J. de pharm. et de chim., Par., 1906, v. 23, p. 357.) 
An abstract discusses the oil of star anise and asserts that a pure 
oil of star anise seed has a congealing point of +18° C., while the oil 
from the leaves and twigs frequently does not congeal even at 
-j-18° C. Fractional distillation shows that the latter contains appre- 
ciable fractions of anise aldehyde. — Pharm. Prax., 1906, v. 5, p. 151. 
Francis, John M., has found not more than 10 per cent of the sam- 
ples of anise oil adulterated. He thinks the most important tests of 
the pharmacopoeia are those of optical rotation (unfortunately not 
available to most pharmacists), specific gravity, solubility, and con- 
gealing point. — Bull. Pharm., Detroit, 1906, v. 20, p. 99. 
Fernan, Albert, reports finding a sample of Russian oil of anise 
which was evidently contaminated with oil of fennel. — Ztschr. d. 
allg. oestrr. Apoth.-Ver., Wien, 1906, v. 44, p. 79. 
Schimmel & Co. point out that anethol, which is included in some 
of the foreign pharmacopoeias in place of oil of anise, may also be 
made from oil of fennel and from oil of star anise and that the ane- 
thol is the same in every case. — Semi-Ann. Rep., 1906, Apr.-May, p. 
78. (See also p. 7.) 
They assert that the melting point of anethol lies between 22° and 
23° and the solidifying point between 21° and 22°. For dissolving 
1 volume of anethol 2 to 3 volumes of 90 per cent alcohol are re- 
quired. — Ibid ., Oct.-Nov., p. 85. (See also p. 9.) 
Gane, E. H., reports on a sample of oil of anise with optical rota- 
tion +0.250, insoluble in 5 volumes of 90 per cent alcohol and did 
not congeal at 10° C. — Proc. Am. Pharm. Ass., 1906, v. 54, p. 340. 
Evans Sons Lescher and Webb found that of 13 samples of anise 
seed oil examined, only 1 was questionable. — Analytical Notes, for 
1906, B, L, & W., Bond., 1907, p. 5.
