only was employed to compare the observations -ndtli. It may 

 be the seasons in the first half of the last thirty years were, as 

 a rule, earlier than in tlie last sixteen years of that period, or 

 it may be the discrepancies given below ai'e due in some measure 

 to the different method of observing which has been adopted 

 since I first became phenological recorder to the Society in 1891. 

 It may therefore be of interest if I append here the variations 

 from the mean for the last sixteen years of the different plants 

 in 1906, and compare them with those obtained when the means 

 for the whole thirty years are employed, the variations from the 

 mean for the last sixteen years being placed in each case first. 

 Hazel nine days instead of two days early, coltsfoot one day 

 early instead of three days late, wood-anemone five days early 

 instead of two days late, blackthorn two days early instead of 

 one day late, garlic hedge-mustard three days instead of four 

 days early, hawthorn two days early instead of one day late, 

 white ox-eye one day instead of six days late, dog-rose six days 

 instead of five days late, black laiapweed four days instead of 

 three days early, harebell four days early instead of its average 

 date, greater bindweed three days instead of four days late, and 

 ivy two days instead of three days early.
