280 CINNAMOMUMS OF NEW SOUTH \YALES, 



The fractions obtained as above orave the followina: results : — ■ 

 First fraction, between 213° C and 235° C, had a specific gravity 

 of -995 @ 16° C, being thus lighter than water. It had a sjaecific 

 rotation of [''] D + 15-86, or half as much again as that obtained 

 for the whole oil. 



Second fraction, between 235 and 245-6° C, had a specific 

 gravity of 1-0166 @ 16° C, and the specific rotation was ["] D + 

 5-066, or less than half that obtained for the whole oil. It is 

 perhaps remarkable that the fractions should have been thus 

 separated, as the mean of the two rotations of these fractions 

 is nearly that of the whole oil. 



Third fraction, between 245-6 and 253° C, had a specific gravity 

 of 1-004 @ 17° C. The material was not sufficient to enable the 

 rotation to be taken. 



The oi"iginal oil is yellowish, inclining to brownish, with a tinge 

 of green. The first two fractions are yellowish to brownish, 

 while the third fraction is distinctly green. 



When the original oil was subjected to the action of cold, a 

 stearoptene crystallised out in small quantity, the temperature 

 being 12 degrees below zero. It was not possible to separate it 

 as it disappeared very quickly on removing from the freezing 

 mixture, evidently melting below zero. 



A portion of the oil was agitated with a solution of potash, 

 the aqueous solution separated, and acidified with dilute sulphuric 

 acid ; no oil separated, but the sokition was turbid ; this was 

 agitated with ether, the ether separated and evaporated, when a 

 minute quantity of an oil was obtained, which became quickly 

 brown, and which had a very strong odour of cloves. When 

 dissolved in alcohol, ferric chloride gave the blue reaction. It is 

 to be supposed, therefore, that the phenol is Eugenol, and that it 

 is only present in traces. 



A portion of the oil was mixed with a concentrated solution of 

 acid sulphite of soda, and well agitated. A small quantity of a 

 cr3'stalline compound was obtained ; this was separated entirel}^ 

 from adhering oil and acidified with dilute sulphuric acid in a 

 graduated tube. The separated oil when measured equalled 1^
