VEGETABLE TALLOW AND WAX. 281 



also produced by a Dipterocarpous plant (Vateria Indica); 

 both are imported from India, but the former, instead of 

 being white, is of a yellowish-green colour, evidently from 

 the admixture of some balsamic resin, which also gives an 

 agreeable balsamic odour to this substance. Its chief value 

 is for the manufacture of candles, which give out a sweet 

 smell in burning. It resembles ordinary tallow in its con- 

 sistency, but small particles appear through its substance, 

 having a resinous lustre. 



Yegetable Tallow (Chinese, from Canton) is procured 

 from the seeds of Croton sebiferum (Nat. Ord. Euphorbia- 

 cece). This kind is very different from the last, being of a 

 cream-white colour, a tallowy odour, hard and brittle, and 

 usually flaky, or in plates about an inch thick, or in lump3 

 bearing the form of some vessel into which it has been 

 melted ; the flakes are apparently caused by different melt- 

 ings being poured into the same pan. It becomes brown 

 by exposure, and evidently contains some acid in abun- 

 dance, probably crotonic ; only a few small lots have been 

 imported experimentally. 



Vegetable Wax (South American). — A singular pro- 

 duct from the leaves of Corgpha cerifera, the Carnauba Palm. 

 (Nat. Ord. Palmacea.) (Plate VIII. fig. 38.)
