 and general constructive. 



COPAL. — It is not certain that true copal has been 

 brought to China in the past. Neither of the genera Trachylo- 

 biuvi nor Hyniencea have been observed in this country, and if 

 the snbstance itself has been bronght in, it has not been dis- 

 tinguished from glim animi^ gum elemi^ or dammar. 



CORCHOROPSIS CRENATA. — H Jg (T'ien-ma). This 

 grows in wild places, along water courses. The leaves are 

 used in the treatment of cancerous sores, boils, and abscesses. 



CYNACHUAI CAUDATUAI.— ^ % ^ (Pai-t'u-huo). 

 Also called g :^ (Pai-ko). This is a creeper growing in 

 mountainous districts, and it somewhat resembles Metaplexis 

 staiDitonii, It is not quite certain whether the root or shoot 

 is used ; one authority giving the former, another the latter. 

 Its virtues are antagonistic to all forms of animal virus, and 

 it is therefore used in all kinds of bites and stings. It is em- 

 ployed internally in all kinds of infections* 



DAMMAR.— PE PJ r^ (Pa-ma-yu). This is the translitera- 

 tion of a Malay name, and is properly applied to the product 

 yielded by Dammara ausiralis and allied species. But with- 

 out doubt it is often used for gum animi^ giim elemi^ copal^ and 

 other substances used in boat-caulking. In this way it came 

 to be applied to coal tar. Dammar is imported into China 

 from Borneo, Singapore, and indirectly from India, for caulk- 

 ing seams in boats. Coal tar now largely takes its place. It 

 is not mentioned in the Pcntsao^ is not known to be used in 

 medicine, and is only mentioned here because it is sometimes 

 confounded with gum elemi.
