MOVEMENTS OF VITALITY. 
In a few instances, such as the transparent 
stem of the chara, the internal current can 
be seen in motion, but in nearly all cases it 
is hidden from our view by opaque cover¬ 
ings. 
If it were possible that the flow of the 
sap could be visible to us, what a scene 
would a forest tree afford, with its mighty 
branches, millions of tubes, and countless 
myriads of cells, all in alternate harmonious 
movement, the vital current flowing through 
them like the waters of the rising Nile 
occupying the channels of the Delta. 
The interest of the phenomena is not ex¬ 
hausted by a consideration of the skilful 
mechanism of vegetables, but there is still 
the fact of the motion thus provided for and 
employed: that wonderful vitality which 
must be tracked by one mighty bound from 
finite to the infinite—from creation to the 
Creator. 
As design is inferred from contrivance, so 
power may be inferred from motion, and the 
life-movement wherever witnessed is a testi¬ 
mony for the Almighty.
