double its own length, began to bend over and point the knobs at 
their extremities towards it, though it was not observed that this was 
accompanied by any increased flow of the secretion from them. The 
sufficiently far to ascertain. It will be seen that the most singular 
feature in the phenomena described is that the motion of the greater

sudden and rapid motions of the stamens of Berberis or the leaves of 
Mimosa. It is also quite certain that the impinging of rain-drops on

kind as in the case of the fly, though apparently somewhat slower. 
After the lapse of twenty-four hours the piece of meat appeared 
decidedly lighter in colour; but an accident prevented the process of 
digestion being further traced. On other leaves were placed a minute 
piece of wood and a small piece of worsted; and in neither of these

It appear, therefore, as if the organised structure of the
