The following statement shews the measurements made by Mr. Popert in some of 

 the plantations of the Tharrawaddy Division in Burma; the results have been obtained 

 by taking the average of some 5 to 10 trees in each : 



A section sent from the Thinganneenoung plantation in Burma, cut from a tree 

 21 years old, planted in 1856, gave 21 rings on a mean diameter of 16'3", the heart- 

 wood of which occupied 14' 5!'. This section shewed 2' 57 rings per inch of average radius. 



From other plantations, also, sections of Teak trees of known age were sent for the 

 Paris Exhibition, but apparently they were not in all cases cut from the base of the 

 stem ; they are, however, instructive as shewing the rate of growth and the number 

 of rings on one inch of mean radius.
