A eucalyptus oil forwarded to the Botanical Institute at Buiten- 

 zorg 1 ) which had been distilled by Dr. Carthaus in the Tengger 

 Mountains of Java, showed d 2 6<> 0,996 (?) and «d -j- 4 18'. At 150 the 

 oil began to boil, up to 200 , 77°/o had passed over, and from 200 

 to 240 , i6°/ . The oil is said to consist principally of cineol. 



In connection with the above we may refer to two eucalyptus 

 oils which had also been produced in the Tengger Hills and which 

 were sent to us by Dr. Carthaus in 1907. The first of these (which 

 Dr. Carthaus surmises to have been derived from Eucalyptus crebra\ 

 was brownish yellow. It contained only a small proportion of cineol, 

 and, besides this, phellandrene and cuminaldehyde (aromadendral?); 

 di 5 o 0,9036, «d — 20°56', cloudy solution with 5 to 6 vol. of 8o°/ 

 alcohol. 



The second oil was derived from a long-leaved species, said to be 

 E. piperita (?) and had a golden-yellow colour; di 5 o 0,8974, «d — 28°26 / . 

 This oil gave a cloudy solution with about 8 vol. 80 per cent, alcohol; the 

 solution in 90 per cent, alcohol, which is clear at first, opalesces when 

 more than 1 vol. of the solvent is added. Cuminaldehyde (aroma- 

 dendral?) and a great deal of phellandrene were found to be among 

 the constituents; the sample was too small to allow of the determin- 

 ation of cineol. In the case of both oils the presence of phellandrene 

 is evident already from the odour.
