 they began to be in motion in every direction ; this movement

frequently revolved, whilst the other on the same petiole was 

 quiescent ; sometimes a few leaflets only were in motion, then 

 almost all of them would be in movement at once ; the whole 

 plant was very seldom agitated, and that only during the first 

 year. It continued to move in the stove during the second year 

 of its growth, and was not at rest even in winter." In our cli- 

 mate the lateral leaflets move up and down, either steadily or by 

 jerks, particularly if the house in which it is growing be shut up 

 very warm. This motion is most evident when the sun's rays 

 are on the plant, it therefore appears to us that it is the action 

 of the sun's rays upon it which occasions the motion of the 

 leaflets. For further particulars see Brouss. mem. acad. scienc.
