PHENOMENA OF REPRODUCTION 65 



ench daughter-cell containing, theoretically, a portion 

 of the germ-cell. 



It follows that the germ-cell has no tendency 

 ' ' within itself to assume a definite living form ; ' ' nor 

 has it any power to become a living form, nor any- 

 thing else. 



Obviously, the microscopic germ-cell, when whole, 

 would be powerless to develop and grow to be a man 

 or woman ; and for a much stronger reason the in- 

 finitesimal fragments of it would be powerless to do 

 these things. 



Apparently, the Creator uses the germ-cell to in- 

 augurate the growth of daughter-cells in the embryo 

 body, in the same manner that a grain of wheat is used 

 to start the growth cf a stalk of wheat. 



Sec. 19. Reproduction, its Phenomena 



All the phenomena of reproduction may be 

 grouped under the following heads: (1) Production 

 of the spermatozoon, (2) production of the ovum, (3) 

 their fusion into the fertilized ovum, (4) production 

 of daughter-cells, (5) distribution, mechanical arrange- 

 ment and grouping of cells, (6) differentiation of 

 cells into the different tissues, (7) waste of cells. 



Sec. 20. Spermatozoon, its Production 



The first step toward the reproduction of a man, 

 woman, or any ether mammal, (m individual of a 

 species which suckles its young), is the formation of
