nerve terniiuals in them respond energetically to all kinds 

 of muscle stimuli.'" (Prof. J. C. Dalton). 



"There are some substances which act as stimuli when 

 applied directly to the muscle, but have no such effect upon 

 the nerves, viz., ammonia." (Prof. J. C. Dalton). 



" In some of the lower animals there are simple forms of 

 contractile tissue in which nerves cannot be discovered and 

 which are irritable.'' (Am. Text-Book Physiology). 



"The scientific biologist recognizes the fundamental like- 

 ness in the structure and functions of plants and animals. 

 Plants feed, breathe, and reproduce exactly as do animals ; 

 respiration takes place in all plants precisely as in animals. 



"Protoplasm, the physical basis of life, is in each and is 

 much alike in each. The cause of the movements of plants 

 is largely due to the direct effect of light upon the sensitive 

 2)rotoplasm of the cells of the motile i)arts." (D. FI. Camp- 

 bell, Ph. D.) 



"Plants are exhausted by over exercise and require rest, 

 and like animals they are lulled and put to sleep by chloro- 

 form and narcotics ! The faculty of responding to external 

 irritation by internal movements and change of form belongs 

 to cells and holds good in the vegetable as in the animal 

 kingdom. All M. Cohn's experiments prove that in Mimosa 

 pudica, which is highly sensible to the action of light, heat, 

 electricity and touch, the propagation of the external excite- 

 ment proceeds in the same mode as in animals." (Somer- 

 ville Molecular and 'Microscopic Science). 



"Mechanical irritation of the glands of Drosera rotundi- 

 folia by insects causes secretions." (Prof. Goodale). 



"The three delicate hairs on each face of the trap and the 

 median line of Dioncea muscipida are exceedingly sensitive, 

 the lightest touch upon one of the hairs will cause the valves 

 to close instantly." (Prof. Goodale). 



"In Drose^^a the secretions of the hitherto neutral glands 

 become acid in consequence of the stinmltis of insects. On 

 stinnilation of Dionoea, electric currents arise in the leaves,"
