Dendrocalamus. — Measurements of culms Nos. 1 and 2 
were made daily from June 19 to July 18 at 7.30 A.M. and 
5.30 P.M. Hourly measurements showed that these times 
divide the periods of more and of less rapid growth some¬ 
what sharply. 
In the following table (Table XI.) the average growth per 
hour from 7.30 A.M. to 5.30 P.M. (day) and from 5.30 P.M. to 
7.30 A.M. (night) is recorded in mm. The date in each case 
refers to the end of the 24-hour period. And the height at 
this time (7.30 A.M.) is recorded in centimetres. The remarks 
apply to the weather during the first ten hours of the period 
Table XI.
