through the different periods of time. To cite a few examples ; 

 Thea transpired 0.6956 gram per n dm. per day at the beginning 

 (conf. Table I), 0.331 at the minimal period^^ (conf. Table III), 

 and 0.934 at the end of the experiment (conf. Table VIII). 

 Their relation is, therefore, 2.1 : 1 : 2.8. In Ternstrœmia the 

 amount of transpiration was 0.419 at the beginning, 0.328 at 

 the minimal period and 1.802 at the end, so that their ratio
