A Three-fold Development. 163 



gans, the nerves, the spinal cord, the brain of an ape or 

 a dog, correspond with the same organs in the human 

 subject." Is the one the product of evolutionary devel- 

 opment, while the other has needed the special creative 

 fiat of the same infinite intelligence which planned the 

 growth of the first? I cannot believe anything so incon- 

 sistent as this. But the skeptics of evolution say to us, 

 where are the "missing links" showing all these changes 

 from moner to man? Show us the fossil monkey-man or 

 man-ape; ;give us a sign that we may believe. They do 

 not know that in their own bodies have been already 

 given all the connecting links from the lowest form of 

 life, up to and including man himself. Standing forth 

 like milestones, on the road of evolution, over which all 

 organic life has moved, have been the changes and modi- 

 fications in their own physical bodies. Beginning life in 

 the single cell, as all other living organisms do, do they 

 become man at once? Certainly not. We must all pass 

 through changes and modifications showing the steps by 

 which we have ascended from the lower to the last and 

 highest form so far seen on our earth. At first, the sin- 

 gle cell that is to become man, divides by simple fission 

 into two cells. Here the amoeba stops, but man must go 

 farther. He has, successively, the forms of lower life 

 of past time, is sponge, worm, fish, reptile, monkey and 

 ape, before he takes his final form and we say a man 

 child is born to us. 



If we go back to the egg from which man is devel- 

 oped, we shall find it only about one one hundred and 

 twenty-fifth of an inch in diameter, and yet, within this 

 exceedingly small space is compressed the results of 

 millions of years of development. Heredity has already 

 marked out and determined the being that shall come 

 from that seemingly simple mass of protoplasm. Let 

 us follow the series of changes through which this em- 

 bryo of man passes during its unfolding and develop- 

 ment. At first it divides into two cells, as does the am- 

 oeba; then it takes successively the sponge form, and 

 then differentiation changes it to and gives it the organs 

 of a worm. Later it has gill slits on each side of its 

 neck with arteries leading to its gills, and it has become 

 fish-like. Then these slits are closed and replaced by
