The odorous principle was entirely taken up by petroleum 

 ether, upon allowing the petroleum ether to evaporate slowly, an 

 abundant crop of large, colourless, tabular crystals was obtained, 

 together with a pale yellowish-brown oily fluid. These crystals, 

 after washing with cold petroleum, were submitted to a series 

 of recrystallizations in order to remove traces of the odorous 

 matter. They were finally obtained quite odourless, and foimd 

 to possess the following properties : — Soluble in petroleum 

 ether, ether, alcohol, chloroform and benzol. Insoluble in 

 diluted solutions of potash, soda or ammonia. Sulphuric acid 

 dissolved it in the cold without production of colour, but if 

 heated the solution became purple red. The alcoholic solution 

 was neutral in reaction, not coloured by ferric chloride or 

 precipitated by basic lead acetate. It did not reduce silver 

 salts. 



The melting point (uncorrected) was found to be 120 — 121 

 F. (49° C), and after melting it would remain fluid at ordinary 

 temperatures for days if left undisturbed. 



By burning with copper oxide in a current of oxygen the 

 following results were obtained : 



'2931 gram yielded 7490 gram 00' and -1804 gram H' O. 

 •2703 gram gave '6912 gram CO' and -1690 gram H^O. 

 These results agree with the empirical formula C^^ff *0 



The uncrystallizable portion of the petroleum ether residue 

 was found to consist of the odorous principle, a fixed oil and a 

 very considerable proportion of ethylmethylparacoumarate, the 

 latter doubtless prevented from crystallizing by the presence
