case of the other five samples the saponi- 

 fication and acid numbers varied con- 

 siderably from standard. In several in- 

 stances the admixture of resin and gur- 

 jun balsam could be clearly demon- 

 strated. Of the five commercial samples 

 of capsules containing Sandalwood Oil, 

 one was found to meet requirements as 

 to quality. 



Incompatibility of Phenazon, Sodium 

 Salicylate and Magnesium 

 Sulphate, 

 A solution of 0.36 gramme of phena- 

 zon, 10.8 gramme of sodium salicylate 

 and 28.8 gramme of magnesium sulphate 

 in 240 mils of water, when set aside for 

 some time deposits a crystalline body, 

 consisting of 55% of phenazon, 40.1% of 

 salicylic acid and 3.5% of magnesium. 

 At 138° C. the crystals liquefied with de- 

 composition. H. Finnemore and J. A. 

 Colverd produced the same crystals by 

 interaction between 2 molecules of 

 phenazon and i molecule of magnesium 

 salicylate. The crystals are white, read- 

 ily soluble in hot water, but sparingly 

 soluble in cold water. The aqueous so- 

 lution fluoresces similar to that of a 

 quinine salt, but to a lesser degree. 



Volatile Oil of Ravensara. 



Ravensara aromatica J. F. Gmel, is 

 according to Ferraud and Bonnafous, a 

 member of the Lauraceae family. It is 

 found growing in abundance on the 

 high plateaus of Madagascar. Distilla- 

 tion of the leaves and young branches 

 yields an ethereal oil in abundance. This 

 oil possesses a pleasant, aromatic odor, 

 resembling that of camphor and eucalyp- 

 tus. The greater part of the oil consists 

 of a hydrocarbon, CuHoq- It also con- 



tains an oxygenated portion, which, 

 however, is only separated with diffi- 

 culty from the hydrocarbon. The hydro- 

 carbon portion of the oil is a colorless, 

 clear and mobile liquid, specific gravity 

 0.8809, and boils at 171-172° C. 



Norwegian Oil of Turpentine. 

 H. W. Fosse has published an ex- 

 haustive article on this subject, from 

 which the following is taken: The oil 

 is obtained by subjecting the com- 

 minuted wood of the cedar and pine to 

 a boiling process under a pressure of 

 from 6 to 8 atmospheres. The opera- 

 tion is carried on in a closed iron vessel, 

 the wood being treated with a sulphite 

 solution, such as is employed in the 

 manufacture of cellulose. The vapors 

 resulting are collected and concentrated, 

 and will, after condensation, form two 

 layers, one of which consists of the im- 

 pure oil and the other of water. As 

 far as could be determined the terpenes 

 contained in the wood are not altered 

 by the boiling process. Combinations 

 possessing a disagreeable odor, however, 

 are formed, and these impart to the re- 

 sulting oil a foreign odor. It is possible, 

 however, to remove these by treatment 

 with chlorinated lime and hydrochloric 

 acid. An examination of the crude 

 product showed that this contained, be- 

 sides terpenes, also sesqui-terpenes and 

 oxygenated products, which seem to be- 

 long to the class of mercaptans. These 

 latter are unquestionably the result of 

 the process employed. The terpenes of 

 the crude oil consist in the main of 

 dextro-rotary pinene and small quanti- 

 ties of sylvestrene. The purified oil 

 seems to be entirely free from mercap- 

 tans, and does not possess the disagree- 

 able odor of the crude product.
