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

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
