I. THE MUSCLES, NERVES, AND BRAIN OP VEGETABLES 



I 



I« 



Vegetable mujcles evinced hy their clofing their cor oh ^ and calyxes ^ and moving their 

 leaves in confequence offtimulus. Hence alfo vegetable nerves both ofjenje and mo^ 

 tion. When one fart of a leaf of mimofa is touched the whole leaf falls. Hence

alfo a vegetable brain or common Jenjor turn* i. 1'heir irritability Jloewn by the ab^ 

 JorptioHf and circulation of their fluids . By electric flsocks. By the a/cent ofjap- 



jutce 



3. Their /enjibility Jhewn by the collaps ofmimoja. By clofing their petals 

 from defe£l offlimulusy as in darknefs and cold. By the males and females bending 

 to each other, 4. Their volition fhewn from hedyfarum gyrans. From polymorph a 

 marchantia. From tendrils of vines. From their fleep, 5 . Their ajfociations of 

 motion fhewn hy their clofing their petals ^ "performing ahfcrption and circulation of 



fluids. 



Their acquired habits. Grains and roots from thefouth vegetate fooner. 



Apple-trees. Senfitive plant. Berberry. 6. Vegetables pojefs a fenfe of heat, 

 of light, and of moiflure, and confequently poffefs a brain or common fenf or ium, 

 7. They poffefs afenfe of touch and a common fetforium. 8, How do the anthers 

 and fligmas find each other? hy afenfe offmell. Adultery of collinfonia. 9. From 



their abforptions, fecretions, fenfes, love andfleep, they muft poffefs a hrain. Does 

 this reftde in the pith of each individual hud i 



? 



I. The various motions of peculiar parts of vegetables evince the 



cxiftence of mufcles and nerves in thofe parts, fuch as the clofing of 

 their petals, and calyxes, at the approach of night, or in cold or wet 

 weather; though the fibres and nerves, which conftitute thefe mufcles, 

 are too fine for anatomical demonftration. 



Some vegetables fold the older leaves over the new buds at the ex- 

 tremity of their ftalks during the night, as alfine, chick weed ; othe 



the mimofa, fenfitive plant, fold the
