oil is exceedingly meager, but that for careful study commercial oil 
will not suffice. — Pharm. Rev., Milwaukee, 1906, v. 24, p. 326. 
Smith, Kline & French Co. report on the examination of 1 sam- 
ple of oil of erigeron. The optical rotation was abnormal, being 
+69° 7'.— Lab. Rep., S., Iv. & F., 1906, p. 23. 
OLEUM EUCALYPTI. 
Schimmel & Co. point out that oil of eucalyptus has, occasionally, 
also a greenish shade. With regard to the cineol estimation they 
refer to their statement in connection with cajuput oil. — Semi- Ann. 
Rep., 1906, Apr.-May, p. 73. 
Evans, John, says a due proportion of cineol is determined by 
observing the behavior of the oil when stirred with half of its volume 
of phosphoric acid (sp. gr. 1.75), Phellandrene is detected by the 
addition of glacial acetic acid and sodium nitrite, formation of a 
mass of insoluble crystals of phellandrene nitrite. — Apothecary, Bos- 
ton, 1906, v. 18, p. 908. 
McCrae, J. (Transvaal Agricultural Journal, v. 4, pp. 26-28) 
reviews the production of oil of eucalyptus and the mode of prepara- 
tion. He points out that the Australian oil industry has progressed 
through taking care to produce a uniform quality of oil of euca- 
lyptus. — Bot. Centralbl., Cassel, 1906, v. 101, p. 383. 
Jackson, R. C., records a comparative study in the production of 
oil of eucalyptus from Eucalyptus oleosa and Eucalyptus globulus. 
He finds that the leaves of E. oleosa contain comparatively more oil 
than the leaves of E. globulus. Also records a study of the composi- 
tion and properties of the oil. (From Amer. Soap. Journ.) — Chem. 
Report, Cothen, 1906, v. 30, p. 37. 
Baker and Smith discuss the characteristics of an oil of Eucalyptus 
calophylla and. also of the oil of Eucalyptus cliversicolor. (Oil and 
Color m. Journ., 1906, v. 29, p. 1795.) — Ibid., v. 30, p. 266. 
Schimmel & Co. direct attention to an article by H. G. Smith, (Jo. 
and Proc. of the Royal Soc. of N. S. Wales) in which he gives the 
indices of refraction and a few other properties of 118 authentic 
eucalyptus oils which, with few exceptions, had been distilled at the 
Technological Museum of Sydney from leaves of which the botanical 
origin had been determined by Baker. — Semi-Ann. Rep. Schimmel & 
Co., 1906, Apr.-May, p. 34. 
Brandel, I. W., reviews some of the more recent literature relating 
to oil of eucalyptus, its properties, and composition. — Pharm. Rev., 
Milwaukee, 1906, v. 24, p. 89. 
Schimmel & Co. review some of the recent literature relating to oil 
of eucalyptus. — Semi-Ann. Rep., 1906, Oct.-Nov., pp. 35-38.
