SYSTEMATIC ANALYSIS OF MAN. 21 



8. PHYSIOLOGY, or Bio-Dynamics^ treats upon the 

 purposes, uses, functions, actions, properties, results, and 

 relations of the various parts of living things. 



9. ANATOMY, or Bio-Statics, treats upon the struc- 

 ture, viz., color, size, form, surface, position, and compo- 

 sition of living things. 



10. HYGIENE treats upon Health, what will im- 

 prove and preserve it, what will impair and destroy it ; 

 and also upon the means best adapted to produce and 

 preserve a desirable condition for use and appearance in 

 the various parts of living things. It also draws in a few 

 practical facts from its professional co-divisions. Hu- 

 man Hygiene treats also of the mind, so far as its condi- 

 tion is dependent on the body. 



11. PHYSIOLOGY, ANATOMY, AND HYGIENE may be 

 treated in either a professional or a popular manner: 

 their co-divisions, treating upon the effects of disease, 

 its cure, the nature and use of medicines, and manual 

 operations, are professional. 



12. THE PROFESSIONAL STUDY of Anatomy, Physi- 

 ology, and Hygiene, includes all their details and modes 

 of expression, requiring years of time in connection with 

 the study of their co-divisions, and, for skilful applica- 

 tion in curing disease, much experience and disciplined 

 observation. 



13. THE POPULAR STUDY of Physiology, Anatomy, 

 and Hygiene, includes only so much of them as is of use 

 to all classes of persons : the whole of Hygiene, much 

 of Physiology, and less of Anatomy. Few details are 

 required ; few technical terms, and not one technical ex- 

 pression (that so much abound in the professional study) ; 

 very little of the mere mechanical, very little of drudgery : 

 whatever is curious, whatever is interesting, whatever is 

 instructive or practical, is appropriate. It is brief, and 

 at once matures its fruit for use in every-day life.
