May (our spring flowers), 28 appeared after the mean date and 
2 before it; and of the 30 which come into flower after the 
middle of May (our summer flowers), 24 appeared after the mean 
date, 3 before it, and 3 on the same day as the mean. The spring 
flowers were on the average a little over a fortnight late (15-3 
days), and the summer flowers a little over a week late (8T days). 
Dividing the period of observation into three, the average date 
of the first 20 species flowering up to the third week in April is 
16‘0 days late ; of the next 20 flowering up to the end of May or 
beginning of June, 12*7 days late ; and of the last 20 flowering up 
to the end of July, 6*4 days late. Yegetation was thus most back¬ 
ward in the early spring, about three-fourths as backward towards
