 disease and spread it through the com- 

 munity, a possibility which increases as 

 society condenses. 



No doubt eminently fatal acute diseases 

 may prevail in a population where the 

 standard of health is high. That is why "a 

 high rate of mortality may often be ob-

 of persons affected with disease is small." 

 All the same, healthy persons are the most 

 immune in such cases, the weaklings serv-

"On the other hand general physical de- 

 pression may concur with the prevalence of 

 chronic maladies and yet be unattended 

 with a great proportion of deaths." 

 Leckey observes this, adding that such an 

 anaemic condition of large numbers in a 

 population is ministered to by sanitary 

 science itself, also by the modern rush of 

 people to cities. He thinks it very doubtful 

 whether our improved standards of living 

 and our improved knowledge of sanitary 

 methods altogether counteract this tendency
