36 DEATH.

 the vigour originally imparted by the 

 parents ; partly on the activity and vigour 

 of the chemical changes going on in the 

 protoplasm of the body and the appro- 

 priated pabulum ; and partly on the 

 general care and management bestowed 

 during the life. Life may well be likened 

 to the spin of a top, in which the spin is 

 started by the spinner ; its vigour being 

 imparted by the force given to the spin, 

 and the continuance of the spinning by 

 the care and assiduity of the whipping : 

 its ceasing to spin is analogous to death. 



As to difference between the life of 

 plants and animals : life being the product 

 of protoplasm, and protoplasm being 

 present alike in plants and animals, both 

 have life ; and the only difference there 

 can be between plant and animal life is 

 that of degree or quality ; and for the same 

 reason there can be no other difference 

 between animal and human life than that 

 of degree and quality. The greater the 

 quantity or proportion of protoplasm the 

 more of life ; and the higher the quality 

 the greater the vigour of life. 



Death is the result of the ceasing of the 

 chemical changes that go on in the proto-
