A very inferior gutta is, or rather used to be, obtained 

 from the Jelutong, for mixing with the true gutta. Mr. 

 Murton (Journal No. 1 p. 107) states that Gutta Jelutong is 

 obtained from a species of A lyxia ; a statement opposed to 

 the description given me by the Bornean collectors, from 

 which it would appear to be the product of a lofty tree, 

 taller than any of those yielding the true gutta (i.e., over 

 100 feet in height.) Growing on both hills and in swampy 

 land, with dark coloured bark, leaves 5" long o' f f broad, 

 green above and light below, seeds in black pods like those 

 of a bean 9 to 10 inches in length, each pod containing 8 to 

 10 seeds. The timber is white, very light, tough, and much 

 resembles that of the Palye. 



The collectors state that there is no such natural product 

 as Gutta Merah or red Gutta; the colour being due to the 

 admixture of filings from the baric of the tree in the pro- 

 portion of J filings to f gutta ; as it is said that the Chinese 

 traders, unaware of the adulteration, prefer the red or adul- 

 terated to the natural Gutta.
