The Evidence Furnished by Embryology 



every living person, creature and thing in all the world has 

 been developed from a single cell. The first and original life 

 cell contained the potential powers of all future life whereas 

 the cells from which life now begins contains the history of 

 the past and the potential powers of development which are 

 possessed by the species to which the cell belongs. These 

 animal cells are all made up of the same substances. They 

 are round and are almost microscopic In size. They all have 

 a tough, skin-like, transparent outer covering which surrounds 

 and holds within its walls a protoplasmic substance and float- 

 ing within this substance is a globular speck which in most 

 cases can only be detected with the aid of a miscroscope. This 

 globular speck is the germ of the future body. It is the life 

 spark which contains the potential powers of development. 

 There Is no apparent difference in the form, size and com- 

 position of the germ cells of all the mammals. In fact, the 

 germ cells of a man, a mouse, a dog, elephant, cow, horse, 

 monkey or any other mammal are apparently the same but 

 they each contain far different ancestral history since their 

 remote ancestors started on different roads In their ascent 

 of life. When these germ cells begin their process of growth, 

 the first noticeable change Is a division by partition or seg- 

 mentation. The original cell is divided into two, the two 

 into four, the four into eight, etc., until the adult form is 

 reached when by multiplication and division the number has 

 reached into countless millions. As the original cell begins 

 its work of multiplication by division, each cell is put to work 

 in building up the complex structure of the species — some 

 working on one part and some on another but all in coopera- 

 tion with the whole plan. One set of cells have been work-
