No. 420. Camphor, obtained by distillation from 

 the wood of Cinnamomum Camphora, Nees, a tree of 

 Formosa, Japan and China. It is also cultivated in India 

 and Ceylon. In the latter country successful experiments 

 have recently been carried out for extracting Camphor 

 from the leaves and twigs. Camphor of commerce is 

 obtained from the root, trunk, and branches, broken up 

 and heated with water in closed vessels, the volatilised 

 Camphor being sublimed upon Rice-straw. It is further 

 refined on its arrival in Europe. Samples of crude and 

 refined Camphor are shown, also specimens of Camphor 

 wood and Camphor oil. From this oil, Safrol, the prevail- 

 ing ingredient of Oil of Sassafras Root [No. 423], is largely 

 prepared in Germany. {See also Sumatra Camphor,
