 surrounded by the cambium and latex forming tissue.

WIND TWIST. 



In positions where trees are subject to strung winds from one 

 direction the trees take on an odd form which is known as winn 

 twist. There are some very good examples in the Botanic Gardens. 

 The trunk of the tree chiefly in old trees shews a series ol spiral 

 ribs usually rising from right to left. Some times the trunk is 

 distinctly flattened in the direction facing the wind. Where the 

 wind has had the greatest force the trees are very curious. There 

 is a close series of transverse ridges with depressions between on the 

 side facing the prevailing wind, from the bottom of the trunk to the 

 top of the higher thick branches. This gives a most curious ladder- 

 like appearance to the trunk. 



Trees like this are decidedly troublesome to tap as the cuts have 

 to run up and dow n over the waves ot bark and wood and it » 

 difficult to get the latex to run just where it is wanted to flow.

MALAY DRUGS. 



KfcLANTAN, 

 September 16M, i9°° 



Dear Mr. RlDLEY, — Some time before his leaving Kelantan, Dr. 

 (iiMLKiTK told me that you were thinking of revising your 

 on "Malay Materia Medica," and that he was trying to col ect in£ 

 ■nation which might be of use to you. As I had previously ^ 

 Dr. Gl.Mi ette in collecting notes on other subjects I tried to do 

 same m this case; but unfortunately I had to move from kou bha J 

 into the interior just about that time, and was only able to e ^ 

 list of diseases and their cures (abstracted from Y"^^ 

 Malay friend and instruct him to question any available _ioi 

 concerning them. I have now had a letter from him saying tha ^ 

 has questioned four or five Toh Bomo without success, as i j f ^ 

 not recognise the name of the plants (nor, probably, the nam 

 diseases as translated by me ), and enclosing two short isto , o 

 1 send you these lists, but 1 feel sure that they are really too 6 

 to be of any use for your purpose.
