56 NOTES ON OUTTA PEKCHA. 



the last named round form, or Serapit, this kind yields very 

 good gutta. The milk of the first and third mentioned is 

 collected indiscriminately, and the produce is known as Gutta 

 Menungan or Gutta Bum, the last name, however, being 

 applied to the hard product of an entirely different tree in 

 Perak (See Mur ton's Report)* 



This Caoutchouc or rubber is prepared by the addition of 

 Nipah salt to the milk, and stirring ; and is sold in the form 

 of black greasy looking balls about half a catty weight each, 

 these being threaded on a strip of rattan for convenience of 

 transport. 



With reference to Gutta Serapit Menungan, Mr. Collins 

 gives the following at p. 24 of his " Report on the Caout- 

 chouc of Commerce." — Vernacular names, Gutta Susu or 

 Susnh (Mai. Milk Gum). Jintawan, variety a; Jintawan Susu, 

 or Milky Jintawan, variety b. ; Jintawan Bulat, or round 

 fruited Jintawan, and c. Ngret or ISTgerit Jintawan 9 Also 

 variety a, Serapit, most common variety ; b. Petabo, the best 

 variety ; and variety c. " Menungan, ' y the greatest quantity, 

 Getuh Katjai (Sumatra.) ?" 



Mr. Collins further adds that when this Caoutchouc first 

 appeared in commerce (1864) he succeeded in identifying it 

 as the produce of Urceola Elastica, partly from the accounts 

 of Motley, Low, Roxburgh', etc.. and partly from Campbell's 

 notes arid specimens in the British Museum. Judging from 

 the small woodcut illustration of Urceola Elastica given at 

 page 1103 of Lindley and Moore's Treasury of Botany, the 

 Boriiean plants here referred to by me certainly do not be- 

 long to that species, although the description appended is 

 fairly truthful and evidently refers to the SZrapit, 



Murton, at p. 12 of his contribution to the history of Gutta- 

 producing trees, points out that the flowers of Urceola (one 

 species only being known) are in terminal panicles or cymes, 

 whereas in the Serapits they are axillary. 



The above are Mr. Burbidge's notes on this subject, which 

 he was good enough, while busily engaged in other matters, 

 to put together at my request. I trust I may be pardoned if 

 I add a few remarks of my own from information which 

 I have gathered from veteran Bornean Gutta and Rubber 

 collectors and others, both Kadayans and natives of Brunei,
