 when plotted, and (2) the unusual uniformity of increase which permits 

 the taking of samples which show growth in 12-hour periods for two weeks

after flowering. The curve of growth as found by Brenchley was quite 

 similar to that shown in figure ii. The same straight line is apparent 

 during the period of rapid starch infiltration, despite the fact that she 

 took samples only every third day. The results seem to agree in a general
