The collection of data and the calculations which take the 
rate of decrease of the various branches into account, while simple, 
are extremely laborious and consume much time. The collection 
of such extensive data for a very large number of plants is scarcely 
possible. Such data are desirable in the analysis of the sources of 
the variability and may indicate the proper methods of obtain- 
ing from a larger number of plants the data that will admit of 
more general analysis and comparison. 
The question naturally arises whether in a plant with a long 
 blooming-period such as chicory the random collection of data at 
intervals of every third day throughout the flowering period will
