Previous work on the woods of this region was as follows: 



Gamble, J. S. A Manual of Indian Timbers. This is by far the 

 most complete piece of work on eastern timbers. The notes are very 

 full and I have quoted from them very largely in my species notes. 



Vax Eeden, F. W. Houtsoorten van Nederlandsch Oost-Indie.-Kol. 

 Museum te Haarlem 1900. This gives very useful notes on a large 

 number of species. 



Ridley, H. N. Timbers of the Malay Peninsula. Agric. Bull. S. 

 S. and F. M. S. (1901-2). Gives excellent notes on a large number 

 of species of the Malay Peninsula. 



Nordlinger, H. Holzquerschnitte. Gives very fine cross sections 

 of a number of Indian woods and some very brief notes as to structure. 



Wiesner. J. Die Rohstoffe des Prlanzenreichs. Vol. II. Describes 

 in detail a few species and lists a number of others from this region. 



Janssonius, H. II. Mikrographie des Holzes. Describes in great 

 detail a number of Javanese species. 



Laslett. Records tests of the strengh of a number of Indian timbers. 



Stoxe, H. Timbers of Commerce. Includes a very few eastern 

 timbers. 



Boulger, G. S. Wood. Gives brief notes on quite a number of 

 species. 



Newton, H. In 1882 published the results of a number of tests on 

 about twenty different timbers of the Straits Settlements. The botanical 

 determinations for this work were very uncertain and it is often very 

 difficult to determine just what wood was meant.
