2o6 PHARMACEUTICAL BACTERIOLOGY. 



able clothing, the right sort of exercise for body and mind, the simple life 

 rather than the strenuous life, avoiding bad habits of all kinds, abundant 

 fresh air, etc., all tend toward longevity. To argue that we should go un- 

 clothed is as absurd and unreasonable as to teach that sheep should be 

 shaved. To adhere to a wholly vegetable diet is irrational simply because 

 we are organically adapted to a mixed diet. An excessive meat diet is also 

 very pernicious. 



Occupation is a potent factor in predisposing to disease, and in lon- 

 gevity. The following table adapted from a report by Ogle will serve to 

 make this clear. The high mortality rate among street-hawkers is due to 

 several causes chief of which are low-living, exposure to inclement weather, 

 and the greater exposure, in the squalid districts of large cities, to the primary 

 causes of disease. The low mortality rate among clergymen is due to a 

 comparatively simple though comfortable mode of Hving; while in the case 

 of the farmer and gardener, the out-of-door life is the favorable influence. 

 The list represents ages ranging from twenty-five to sixty years, therefore 

 adults.
