CHAPTER VI. 



SYSTEMATIC ANALYSIS OF ORGANS. 

 General Anatomy, Physiology, and Hygiene. 



TISSUES, FLUIDS, AND GASES I PROPERTIES. 



SECTION I. 



Tissues and their Properties. 



NOTHING affords a more profound source of admira- 

 tion to the intelligent mind, than simplicity of means for 

 producing important and varied results. Nothing pleases 

 more than to find a result unexpectedly produced by the 

 varied action of a cause previously understood. How 

 astonishing and pleasing to find that all the varieties and 

 shades of color may result from mixing only three, Red, 

 Yellow, and Blue ! We look upon the bright red blood 

 almost with veneration, when we learn that the life of 

 the body is in its keeping, and that all the organs are 

 built up, kept in repair and at a proper temperature, by 

 means of that single fluid. How much more of gran- 

 deur pervades the heavens when it is discerned that in- 

 stead of cycles upon cycles, spheres within spheres, the 

 incomprehensible jargon of combined forces of the an- 

 cients, one simple law of gravitation pervades all space, 

 and keeps all bodies in their orbits ! The causes of or- 

 ganic action will therefore especially delight the mind. 



What is the subject of Chap. VI. ? What is the subject of Section I. ? What 

 said of simple causes?
