DEFINITIONS AND PRINCIPLES, 



1. All the objects in the material world are divided into 

 Organic and Inorganic. 



2. Cells, Membranes, and Fibers. — In organic bodies, the 

 matter composing them is arranged in the form of cells, mem- 

 branes, and fibers, variously combined. In inorganic bodies, 

 though the particles are often arranged with mathematical 

 precision in particular modes, cells, membranes, and fibers 

 are not formed. 



3. Life. — The principle of life is always associated with or- 

 ganic, but never w T ith inorganic bodies. 



4. Examples of Organic and Inorganic Objects. — Or-

 the end toward which all the animal kingdom has tended 

 from the first appearance of ibe Palaeozoic fishes." — Agassiz 

 and Gould. 



6. Anatomy and Physiology. — Anatomy is the science that 



Questions. 1 Give the two kingdoms of the material world. 2 What is the arrange- 

 ment of matter in organic and inorganic bodies? 3. With which is life associated? 

 4 State some examples of organic and inorganic bodies. 5. Why is man placed at the 

 head of the animal kingdom ? 6. Define Anatomy.
