When the function of perspiration is impaired, good 

 health can never be enjoyed ; hence the propriety of wash-

THE POWER THAT SUPPORTS AND PRESERVES 

 HEALTH 



It must be evident to the reader who has carefully 

 perused the foregoing pages that the preserving power of 

 health can be nothing more than the living power of the 

 system exercising its full and wholesome influence over the 

 vital organs, by which they are kept in a healthy condition. 

 This power, although depending upon matter exterior to 

 the body, may be said to be exerted internally; conjointly 

 with which are many causes having an influence upon 

 health that depend upon the reasoning faculties and the 

 influence of the will. These are, principally, a suitable 

 degree of exercise and rest; the rational indulgence of the 

 propensities and passions; and, in short, the due observ- 

 ance of temperance in everything that is capable of pro- 

 ducing either a moral or a physical effect upon the sys- 

 tem.
