Before speaking in detail of tlie data presented by the four 

 tables giving the history of each leaf, for convenience, we shall 

 bring these data together in a table of averages, in which are given 

 the length, breadth, and surfa'ce development of the leaves, with 

 the rnore detailed data. The „length of leaf" given is the total 

 length of the mature leaf, less its length at the time of the first 

 measurement. 



This correction is necessary, or the total „surface of the mature 

 leaf", and the „daily surface growth" would be given too high.
