It may be seen in the diagram that when the temperature was highest there were rapid oscillations. Averrhoa hilimbi; ansinlar movements of leaflet during a change from bright illumination to shade ; temperature (broken line) remaining nearly the same. of small amplitude, the mean position of the leaflet being at the time nearer the vertical. When the temperature began to fall, the oscillations became slower and larger, and the mean position of the leaf again approached the horizontal. The rate of oscil- lation was sometimes quicker than is represented in the above diagram. Thus, when the temperature was between 31° and.
