peninsula 598 piculs, from the Johore Archipelago 1269, from Sumatra 1066, 

 from Batavia 19, from Borneo 55. The price at Singapore was originally 

 8 dollars per picul ; it rose to 24, and fell about the middle of 1848 to 13, 

 In the course of 3^ years 270,000 taban-trees were felled in order to get at 

 the gum, and nothing has been done to replace them. — Express. 



We cannot help adverting in this place to the superb series of Indian tim- 

 bers in the Exhibition, and also the very extensive collections of woods in the 

 East India House ; the former contain large contributions from the Northern 

 Circars, Coimbatore, Assam, Arrackan and Malabar. The East Indian Mu- 

 seum contains a collection of 1 17 specimens sent by Dr. Roxburgh, 100 from 

 Java by Dr. Horsfield, and 456 from Dr. Wallich, who gave the duplicates 

 of his collection to the Society of Arts, of which they published a list in 

 their Transactions, vol. xlviii. p. 439, and for which they awarded the gold 

 Isis medal. These sufficiently illustrate the great variety and great import- 

 ance of the timber-trees of India, of which the following are the kinds chiefly 

 used. Much useful information will be found in Holtzappfel's Descriptive 

 Catalogue of Woods used in Turnery, to which notes have been added by 

 Dr. Royle*.

* I have here to express regret that my approaching departure for India prevents me 

 from giving so complete a list as I could wish, and entering at length upon details regarding 

 the oeconomic uses of some to which I paid considerable attention in India,
