WOOD-OIL COPAIVA. 



Wood-oil is one of the most valuable products of the 

 Tenasserim Provinces j and the tree which produces the 

 best quality is one of the most widely diffused of our 

 forest trees. It yields too, very abundantly. Dr. Heifer 

 wrote, that 0118 trunk would produce thirty or forty gal- 

 lons each season without injury to the tree. In the re- 

 ports of the Agricultural and Horticultural Societies of 

 India, it is said : " The wood-oil, properly speaking, is a 

 balsam, obtained from several species of dipterocarpus 

 common in many parts of India. By distillation this bal- 

 sam yields volatile oil, a resin being left behind. This 

 o'l, Dr. O'Shaughnessy found to be identical in chemical 

 composition with that of the balsam of copaiva, and he 

 had accordingly used it extensively in his hospital, with 

 exactly the same medicinal effects." " Nor is this arti- 

 cle," continues the report, " likely to become of impor 

 tance in medicine only ; but also in the arts, in many of 

 which copaiva is now used, Copaiva, by the latest ' dry 

 price current,' was at five shillings and six pence the 

 pound, while twenty pounds of the essential oil of wood 

 may be obtained, of the very best quality, for about ten 

 shillings."

NEEM TREE. 



This tree Linnaeus placed in the same genus as the 

 pride of India, which it much resembles, but the leaves 

 are more intensely bitter. It is cultivated by the Bur- 

 mese for its medicinal qualities, for which it is famous 

 ail over India. The bark has been successfully used in 

 India as a substitute for cinchona ; the bitter oil of the 

 fruit is a valuable anthelmintic; the seeds are used in the 

 destruction of insects ; and "the leaves," remarks Dr.
