Sec. 27. Differentiation (Metamorphosis) 

 of Simple-Cells Into Bone-Cells, Mus- 

 cle-Cells, Nerve-Cells, Vascular- 

 Cells, Gland-Cells, Etc. 



A cell is said to be "a simple-cell," when it is com- 

 posed of carbon, hydrogen, nitrogen and oxygen, with 

 a possible trace of phosphorus and sulphur, when it 

 consists of plain protoplasm and before it has been 

 differentiated into a bone-cell, muscle-cell, nerve-cell 

 or the like. To convert a simple-cell into one of these 

 specialized cells certain atoms must be added to it, 

 or taken from it ; or certain atoms must be taken away 

 and others added to it ; or the chemical combination 

 of atoms in it must be broken down and new ones 

 formed. There is no change in the properties of the 

 chemical elements, which compose the human body. 

 For example, the nature and properties of carbon, 

 hydrogen, nitrogen and oxygen remain the same 

 whether they are in or out of the body, and the same 

 is true of every other element. 



The differentiation of simple-cells into bone-cells, 

 muscle-cells, nerve-cells, vascular-cells, gland-cells, etc., 

 is effected by changing the chemical elements, which 

 enter into their composition ; or by changing the pro- 

 portion of these elements to one another and altering
