of specific gravity should be 1.059. — Semi-Ann. Rep. Schimmel & Co., 
1906, Apr -May, p. 72. 
Patch, E. L., says that oil of cassia can be found assaying the full 
amount of cinnamic aldehyde. All of the natural oil examined by 
him contained lead, coming from the lead container in which it was 
imported. — Proc. Am. Pharm. Ass., 1906, v. 54, p. 341. 
Vanderkleed, Charles E., reports that many samples of cassia oil 
respond to the U. S. P. test for rosin, one was adulterated with petro- 
leum. — Proc. Pennsylvania Pharm. ^Ass., 1906, p. 122. 
Baird, J. IV., reports seven samples examined in 1904, four adul- 
terated. — Proc. Massachusetts Pharm. Ass.. 1906, p. 59. 
OLEUM CINNAMOMI ZEYLONICUM. 
Schimmel & Co. give the following as being characteristic of Cey- 
lon oil of cinnamon: Color, bright yellow; specific gravity at 15° C. 
1.023 to 1.040, optical rotation slightly to the left, to — 1°; aldehyde 
content between 65 and 76 per cent; soluble in 2 to 3 and more vol- 
umes of 70 per cent alcohol. — Semi-Ann. Rep. Schimmel & Co., 1906, 
Oct.-Nov., -p. 90. 
The Ph. Brit. Committee of Reference in Pharmacy report on oil 
of cinnamon sa} T s alter details of the aldehyde assay and give mini- 
mum as 68 per cent. — Chem. & Drug., Bond., 1906, v. 69, p. 864. 
An unsigned critique of the Ph. Ndl. IV notes the requirement of 
55 to 75 per cent of cinnamic aldehyde. — Ibid ., v. 68, p. 828. 
Evans Sons Lescher and Webb report on the examination of sev- 
eral samples of cinnamon oil, and point out that the oils of com- 
merce are still found to contain abnormal amounts of cinnamic alde- 
hyde. They append a table showing the specific gravity, rotation, 
and eugenol and aldehyde content of 10 samples examined. — Analyt- 
ical Notes, 1906, E., L. & W., Bond., 1907, p. 13. 
The Ph. Brit. Committee of Reference in Pharmacy says assay 
process for cinnamon water is not required. — Chem. & Drug., Bond., 
1906, v. 69, p. 862. 
OLEUM COPAIBA. 
Schimmel & Co. assert that the upper limit of specific gravity for 
authentic oil of copaiba may be run up to 0.915 at 25° C. They also 
point out that 1 volume of oil of copaiba requires from 5 to 10 vol- 
umes of 95 per cent alcohol for solution. — Semi-Ann. Rep. Schimmel 
& Co., 1906, Apr.-May, p. 73.

copaiba, its preparation, properties, and composition. — Pharm. Rev.,

paiba. — Semi-Ann. Rep. Schimmel & Co., 1906, Oct.-Nov., p. 28.
