mon (bark) is also obtained from Cassia Buruianni. Saigon cin- 

 namon (p. 513) is derived apparently from wild trees growing in 

 the mountainous regions of Anam, the botanical origin of which 

 has not been determined. 



The volatile oils of the members of the Lauraceae vary con- 

 siderably in composition. In addition to the oils of Sassafras 

 and Cinnamon the following may be mentioned: A cinneol- 

 containing oil is found in Ciiniainomnui Oliveri of Australia, 

 Umbellularia calif ornica of Western North America and Laurns 

 nobilis the noble laurel of the Mediterranean and Mexico. A ijor- 

 NEOL-containing oil is obtained from the root of Dicypclliiim caryo- 

 phyUatum of Guiana, the wood of which is known in Cayenne as 

 rose-wood. An oil containing a notable amount of methyl sali- 

 cylate is obtained from the spice-bush (Lindcra Benzoin) of the 

 United States. 



Cinnamomum Camphora, or the camphor tree, is indigenous to 

 China, Japan and Formosa, and is now cultivated in many warm 

 countries as a shade and ornamental tree, growing very well in 

 Southern California and the Southeastern States. All parts of 

 the tree contain a volatile oil which on oxidation yields camphor 

 which latter is obtained by distillation and sublimation. Camphor 

 of poor quality is obtained from C. Parthcnoxylon of Burmah, 

 Malaya and China, and C. glaiidiilifcniin of the Himalayas. Cam- 

 phor is also a constituent of other ethereal oils of this same family, 

 as the Massoy bark oil obtained from the root bark of C. zeylan- 

 icnin and C. Bnrnianni of Java. 



A EUGENOL-containing volatile oil is obtained from Ravensara 

 aroniatica of Madagascar, and Machilns Thunbergii of Japan. 

 Eiigenol is also found in oil of laurel leaves (L. nobilis), Massoy 

 bark oil, the oil of the leaves of Ce3don cinnamon, and the oils 

 obtained from Cinnanwmuni Culilazvan of the Malay Peninsula 

 and China, and C. Wightii of East India, and possibly is also 

 found in DicypeUium caryophyllatum. 



The wood and the bark of Nectandra or Beeberu {Nectandra 

 Rodicri) of Guiana and Brazil contain several alkaloids, one of 

 which is known as beeberine and is supposed to be identical with 

 the alkaloids in Biixiis sempervirens (Earn. Buxaceae) ; pelosine 

 found in Pareira ; and paricine found in the bark of the cultivated
