IX THE VEGETABLE. 



6. The vegetable is a com- 

 pound of many plants that are 

 divisible and capable of mul- 

 tiplication by buds, slips, 

 suckers, or seeds. 



7. The plant has a circular 

 or radiated form, both sexes 

 being often united on the same 

 individual. 



8. The reproauctive organs 

 in the vegetable fall every year. 



9. Fructification is the great 

 end of vegetable existence, by 

 the development of the flower 

 and fruit. 



10. The movements in the 

 vegetable are involuntary, de- 

 pending on a state of turges- 

 ceuce in the vessels, or in a 

 degree of irritability peculiar 

 to their tissues. 



11. The vegetable is en- 

 dowed with an organic sensi- 

 bility without consciousness. 



12. Vegetables possess de- 

 fensive or protective weapons, 

 and many have poisonous or- 



IX THE AXIAIAL. 



6. Animals, some polyps 

 and mollusca excepted, form a 

 whole that is indivisible, being 

 composed of central organs, 

 as the brain, spinal cord, heart, 

 &e. 



7. Animals have mostly a 

 binary form, each half being 

 the counterpart of the other : 

 the sexes are usually separate, 

 although they are united in 

 the inferior classes of mol- 

 lusca and radiata. 



8. In the animal they are 

 permanent during life. 



9. Sensibility and conscious- 

 ness are the highest conditions 

 of animal life, through the ope- 

 ration of the brain and nerves. 



10. The motions of animals 

 are voluntary, depending on 

 the energy of their muscular 

 system, regulated by the will 

 acting through the nerves. 

 Some movements belong to the 

 in voluntary class. 



1 1 . The nervous system con- 

 fers on animals sensibility, 

 accompanied with conscious- 

 ness. 



12. Animals, in addition, 

 are furnished with offensive in- 

 struments for seizing and des- 

 troying prey ; some have a 

 venomous, and others an elec- 

 trical apparatus to accomplish 

 the same end. T. W.]
