Omitting from consideration the small values of interval 
IV, it is again evident that the outstanding feature of interest

was doubtless suffieient to account for the low rate of those 
periods. 
On the marguerites observations were made for a limited 
number of intervals. The plants were in vigorous condition, 
about 37 em. high and beginning to blossom. From a pre-
