HUMAN SKELETON A SPECIAL CREATION 121 



functions of the germ by which it passes, step by step, 

 from an extreme simplicity, or relative homogeneity, 

 of visible structure to a greater or less degree of com- 

 plexity or heterogeneity; and the course of progressive 

 differentiation is generally accompanied by growth, 

 which is effected by intussusception,' [interstitial 



deposit.]

"And so far from the fully developed organism's 

 being simply the germ p^is the nutriment, which it 

 has absorbed, it is probable that the adult contains 

 neither in form, nor in substance, more than an inap- 

 preciable fraction of the constituents of the germ, and 

 that it is almost wholly made up of assimilated and 

 metamorphosed nutriment.' 



This being true, it cannot be said that the germ 

 (fertilized ovum) ever develops into a man or woman. 

 On the contrary it is annihilated ; and its identity is 

 wholly lost among the daughter-cells which are made 

 of the mother's food. 



Herbert Spencer invented what he calls "physi- 

 ological units" or "constitutional units," and "struc- 

 tural proclivity.' But neither he nor any other man 

 ever saw one of these "units," they being wholly im- 

 aginary. In his Principles of Biclogy (vol. 1, p. 368) 

 under "Genesis, heredity and variation," he says: 



'So that though all parts are composed of physi- 

 ological units of the same nature, yet everywhere, in 

 virtue of local conditions and the influence of its 

 neighbors, each unit joins in forming a particular 

 structure appropriate to its place.' 



Could anything be more absurd ?
