TURPENTINE. 



415 



Chian Turpentine-tree Pistacia tcrebinthut. 



The turpentine which comes from it is a yellowish 

 white fluid, having a slight tinge of blue. This flows 

 from incisions made in the trunk and larger branches, 

 first in the lower parts, and by degrees, as these 

 become exhausted, others are cut above. 



A very white limpid and fragrant essential oil is 

 obtained from the fluid by distillation.
