14 f t^ttifi HUMAN BODY. 



^Physiology is oiily .partially known. There are some 

 parts of the body whose use we do not know. In those 

 parts with which we are better acquainted we find much 

 that we do not understand. But many learned men are 

 devoting their whole time to this study, and are con- 

 stantly adding to our knowledge. 



By combining the teachings of Physiology with what 

 we know by experience we construct the science of 

 Hygiene. From its principles we derive rules for the 

 preservation of health. 



Anatomy is a science of Structure. 

 Physiology is a science of Function. 

 Hygiene is the science of Health.
