Tli woodbine of the poets, though likewise the " twisted 

 eglantine" of MILTON. The phenomena observed in its 

 growth have been adduced in favour of the existence of a 

 kt perceptive power" in vegetables. They are certainly 

 curious. The branches shoot out longitudinally, till they 

 become unable to bear their own weight ; and then 

 strengthen themselves by changing their form into a spi- 

 ral. When they meet with other living branches of the 

 same kind, they coalesce for mutual support, and one spi- 

 ral turns to the right, and the other to the left, thus seek- 

 ing, by an instinctive impulse, some body on which to 

 climb, and increasing the probability of finding one by the 

 diversity of their course : for, if the auxiliary branch be 

 dead, the other uniformly winds itself round from the 

 right to the left." Dr PERCIVAL.
