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. 
Van Eeden, F. W. Houtsoorten van Nederlandsch Oost-Indie.-Kol. 
Museum te Haarlem 1906. 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. Ilolzquerschnitte. Gives very fine cross sections 
of a number of Indian woods and some very brief notes as to structure. 
Wiesner, J. Die Rohstoffe des Pflanzenreichs. Vol. II. Describes 
in detail a few species and lists a number of others from this region. 
Janssonius, II. II. Mikrographie des Ilolzes. Describes in great 
detail a number of Javanese species. 
Laslett. Records tests of the strengh of a number of Indian timbers. 
Stone, II. Timbers of Commerce. Includes a very few eastern 
timbers. 
Boulger, G. S. Wood. Gives brief notes on quite a number of 
species. 
Newton, II. 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.
