SOLIDAGO ODOEA. 4,> 



mentioned by Mr. Holmes as being similar to Cortex Cidilaoani 

 Papuanus in the Hanbuiy collection, the botanical origin of which 

 is acknowledged to be '-' unknown." Slightly distinctive botanical 

 peculiarities may be overlooked or misjudged by reason of defective 

 or imperfectly described specimens — but an odour is never to be 

 forgotten — especially by an experienced business nose. 



Sassafras Goesianum, T. & B., Cinnamomum oxtnthoneuron 

 Blume and Massoia aromatica Albertis and Beccari may be 

 identical, but the Massoi bark of Java, Borneo and Sumatra 

 (? Cinnamomitm Kiariiis, Nees) is of very little value commercially^ 

 having but very little aroma. It is referred to by Gmelin* as 

 furnishing a light and a heavy essential oil and a camphor. The 

 bark obtained by Messrs. Schimmel from the Xew^ Guinea 

 Company has been found to contain about 7 per cent, of an oil 

 having a specific gravity of 1-04, boiling betweeen 200° and 

 300^0, and containing about 75 per cent, of engcnol. The portion 

 of the oil soluble in soda liquor boiled between 210° and 245 °C., 

 and among other compounds, contained safrol. The oil also 

 contains pinene, limonene and dipentene. This bark has been 

 minutely imestigated by Dr. Xeumann AVender of Lembergf and 

 compared with other kinds ; he there explains how the bark does 

 not agree with either of the two in the pharmacological collection 

 of the Allgem. osterr Apotlieker-Yerein in Vienna. He observes 

 further, that the Massoi tree, according to the anatomical structure 

 of the bark, is undoubtedly that of a Lauracea, and that in other 

 respects it agrees with the bark of Sassafras Goesianum, or of 

 Massoia aromatica above-mentioned. 



Solidago Odora. 



An essential oil is distilled from the fragrant leaves of this 

 perennial herbaceous plant, which belongs to the tribe CoryvihifercE, 

 and is indigenous to Xorth America, where it is called ''Sweet 

 Scented Golden Piod." (In French, Verge cVor ; and in German, 

 Golclridhe).% The pow^erful odour of this essential oil has been 

 compared to a mixture of anise and sassafras. The sp. gr. of 

 the oil is 0-963.
