Vanillin, has been already mentioned. Another, 

 COUMARIN, is interesting from its occurrence in a great 

 variety of plants. Its composition is C 9 H 6 O 2 , and it 

 has been found in Dipteryxodorata?N\\\&. (Coumarouna 

 odorata, Aubl.), the TONQUIN BEAN, used to scent 

 snuff, Angrczcum fragrans, Reich, fil, the FAHAM TEA 

 of Mauritius, Orchis militaris, L., O. Simia, Lam., O. 

 fusca, Jacq., and O. ustulata, L., Asperula odorata, L., 

 the SWEET WOOD-RUFF, once used to give perfume 

 to Rhine wines, Eupatorium aromaticum, L., and E. 

 glutinosum, Lam., of North America, the Swiss Melilotus 

 ccerulea, Desr., and our M. officinalis, Desr., and An- 

 thoxanthum odoratum, L. Its presence in the latter gives 

 the fragrance to new-mown hay, and in the seeds of 

 FENUGREEK (Trigonella F<xnum-gr<zcum> L.) it causes 

 their use to improve the appearance of inferior hay.

 be added, taking the oils in systematic order.
