These two fractions gave the following constants :— 

Sp. gr. at 15°. Roterion ap Ref. index at 16° 
First fraction 0°8708 +31°2° 1°4660 
Second |. 0:880 +21°6° 1°4658 

The cineol was determined in the second fraction by the 
resorcinol method, giving a result equal to 19°5 per cent. 
of the crude oil, but a phosphoric acid determination only 
gave a result equal to 15 per cent. cineol in the crude oil. 
It is thus evident other bodies in addition to the cineol 
were absorbed by the resorcinol. The alcohol was probably 
terpineol and was in the dextrorotatory form. 
That the greater portion of the oil consisted principally 
of dextrorotatory pinene was demonstrated in the following 
manner:—The rectified oil was agitated for some consider- 
able time with a 50 per cent. cold aqueous solution of 
resorcinol until absorbable bodies were removed. The 
remaining oil had specific gravity at 15° =0°8640; rotation 
dy + 33°6; refractive index at 15° =1°4674, and gave a 
nitrosochloride melting at 104°. 
Although these results are interesting as demonstrating 
great diversity in the essential oils of the Melaleucas, yet, 
it is apparent that Melaleuca Deanei can have no economic 
‘value as an oil producing plant, the chief constituent being 
pinene, and oxygenated bodies are only present in very 
small amount.
