whole matter, is sufficiently authenticated. Certainly it is not 
universal, for cases have been observed in which the papille were 
still functional while pollen was being freely shed; and in many 
other instances, although the pistils had passed the point at which 
they could be fertilized, they had clearly done so but very lately, 
while the amount of pollen accumulated seemed to indicate that it 
pe have ae falling much longer. This is evidently a point 
hich deserves fuller examination, and to which the attention of 
field- i catisty may profitably be directed.
