Abscissa spaces, each two days. 
Ordinate spaces, each 2.5 mm. of movement, and 1 degree of temperature. 
Downward direction means inward of the shrub, and upward means outward. 
The plate shows the movement of the branches in two shrubs : — 
The upper is Lindera Benzoin , the north, south, east, and west branches being indicated by 
the initials N. S. E. W. 
The lower is Salix laurifolia , the respective branches being indicated as for the Lindera. 
The double line between the two shrubs represents temperature. 
The records begin after the leaves were mostly fallen, and continue until the new leaves were 
largely formed.
