it is also true that leaves which spontaneously fall will produce 
buds and a crop of new plants, in the same way as will those which 
are prematurely removed by art for the rien end. ‘The process in 
fact is an adventitious means of propagation. And in the Aspen, 
as a mere conjecture, it may under pion be the same, a 
I have seen as yet no evidence of this. Or is the reason to be di 
covered from a study of arboreal evolution? Perhaps such a ata 
might show the peculiarity to be the remains of a met ethod of 
propagation, remains which now pet no end, yet persist as well- 
nigh useless relics of a bygone pro That the provision for 
such a separation is merely in site cpation of a death of the 
ieiekinte can scarcely be maintained, for such a death is of mere 
accident if it is only such as occurs in ae trees, and in these no 
similar provision exists. In the animal organism the death of a 
part is followed by active cell-changes which lead to its complete 
separation ; but 1 believe there is no instance of an original an 
abiding peculiarity of structure in any part, in anticipation of a 
death which is to be determined solely = accident.
