418 NATURAL HISTORY OF PLANTS. 



of India, often pointed out as a source of colouring matter useful in 

 industry, only yields in drops a yellowish or greyish-green resin of 

 very inferior quality. G. Cambogia* produces a gum-gutta which 

 contains a volatile oil and the resin of which, slightly active as a 

 purgative, is of a pale yellow colour. G. travancorica, 2 on the other 

 hand, is said to yield a gum of a beautiful yellow colour, and it is 

 probable that a useful tinctorial matter might be found in several 

 other species, 3 perhaps in those growing in New Caledonia, 4 which 

 in so many characters approach G. Morella. The resin of Muni/' 

 from Guyana, comes also from the latex of a Glusiacea, long referred 

 to Moronobea coccinea, but which is rather Symphonia globulifera, 6 

 that is the true Bois- de- cochon (pigwood) of St. Domingo. Its 

 yellow juice, blackened in the air, is used to tar ships and cordage 

 and to make torches ; it burns well without producing much smoke 

 or smell. The species of Calophyllum are equally rich in resinous 

 juice, often classed as balm or balsam. The B. de Marie of the 

 Antilles 7 is obtained by incising the stem and branches of C. Calaba 8 

 (fig. 381-384) ; it is greenish, sticky, and tenacious, and is employed 

 as a vulnerary. The tacamac resin of Bourbon 9 is said to be ex- 

 tracted in the same manner from G. Tacamahaca, 10 a fine tree of the
