oil), was obtained, boiling between 155 - 157° O. This was 

 water-white and had a pinene odour. It was found to still 

 contain a small amount of cineol; this was mostly removed 

 by shaking with a few drops of phosphoric acid. The 

 uncombined portion was filtered off, washed and distilled. 

 It had a specific gravity 0*869 at 15° C; refractive index 

 1*4695 at 17° 0., and rotation a D + 25*2°. Although still 

 not quite pure, yet it was sufficiently so to show that a 

 large portion of the oil of this species is dextro-pinene, 

 and the nitrosochloride prepared from it in the usual way 

 melted at 103° O. The cineol was separated from the 

 phosphate and determined to be that substance. 



The oil of this species thus consists principally of pinene 

 and cineol. It is deficient in the required characters for 

 "cajuput." The oil very closely resembles the eucalyptol- 

 pinene oils obtained from certain species of Eucalyptus, 

 which contain about 30—40"/° eucalyptol. It has therefore 

 little commercial value, and cannot compete with 

 Eucalyptus oils. Our acknowledgments are due to Mr. 

 P. H. Taylor for his kindness in cutting the sections 

 illustrated in this paper.
