The Ph. Brit. Committee of Reference in Pharmacy points out 
that the description for oil of copaiba needs revision. — Chem. & 
Drug., Lond., 1906, v. 69, p. 864. 
Smith, Kline & French Co. report on the examination of 2 sam- 
ples of oil of copaiba having specific gravities of 0.901 and 0.896, 
and optical rotations of — 19° 12' and- — 17° 12', respectively. They 
were both soluble in 8 parts of alcohol. — Lab. Rep., S., K. & F., 1906, 
p. 23. 
OLEUM CORIANDRI. 
Brandel, I. W., quotes Pancoast, who asserts that authentic speci- 
mens of oil of coriander had a specific gravity of from 0.869 to 0.872 
and a dextrorotatory power of -|-10 o 30'. A commercial sample 
quoted as “ superior,' 1 at three times the price of ordinary oil, had a 
specific gravity of 0.873 and a dextrorotatory power of -f-12° 17'. — 
Pharm. Rev., Milwaukee, 1906, v. 24, p. 112. 
Schimmel & Co. point out that owing to its . high price oil of 
coriander is frequently adulterated. They report on a sample, which 
had a specific gravity at 15° C. of 0.8752; rotation, -(-33° 29'; saponi- 
fication number 5.5; and was insoluble in 70 per cent alcohol. — Semi- 
Ann. Rep. Schimmel & Co., 1906, Oct.-Nov., p. 28. 
Evans Sons Lescher and Webb report that six samples of coriander 
oil from four reliable sources had specific gravity of from 0.871 to 
0.875, and rotation of from -{-6° 30' to +10° 44', and that all were 
soluble in 3 volumes of 70 per cent alcohol. — Analytical Notes, for 
1906, E., L. & W., Loncl., 1907, p. 16. 
Smith, Kline & French Co. report on the examination of 2 sam- 
ples of oil of coriander having specific gravities of 0.901 and 0.869 at 
15° C. One sample was not soluble in 10 parts of 70 per cent alco- 
hol. — Lab. Rep., S., K. & F., 1906, p. 23. 
OLEUM CUBEBJE. 
The Ph. Brit. Committee of Reference in Pharmacy points out that 
the optical rotation for oil of cubeb should be — 30° to — 40°. — 
Chem. & Drug., Lond., 1906, v. 69, p. 864. 
OLEUM ERIGERONTIS. 
Henkel, Alice, mentions Erigeron canadensis L., also known as 
Leptilon canadense (L.) Britton, commonly known as Canada flea- 
bane, horseweed, colt’s tail, prideweed, and bitterweed, as being 
found in fields and meadows, along roadsides, and waste places 
almost throughout North America. — Bui. Bur. Plant Ind., U. S. 
Dept. Agric., 1906, No. 89, p. 28. 
Rabak, Frank, discusses the properties of an oil obtained from 
fresh Erigeron canadensis and points out that our knowledge of this
