Sanitary 
Cleanness 
ioR HOUSEHOLD BACTERIOLOGY 
Sanitary cleanness requires the cleanness of the in¬ 
dividual, of his possessions, and of his environment. 
Each individual is directly responsible for his per¬ 
sonal cleanness and that of his possessions; but over a 
large part of his environment he has only indirect 
control. Not until this personal responsibility is felt 
in its fullest sense, and exercised in all directions to¬ 
ward the formation and carrying out of sufficient and 
efficient public laws, will sanitary cleanness supplant 
the cure of a large number of diseases by their pre¬ 
vention. 
When the right of cleanness is added to the right to 
be well fed, and both are assured to each individual 
by the knowledge and consent of the whole people, 
then the great gospel of prevention may make good 
its claim. Towards this ideal tend all the problems 
which the science of bacteriology is endeavoring to 
solve. These problems cannot be solved in the labora¬ 
tory alone. Each house in the land, presided over by 
an active, intelligent supervisor, should become an ex¬ 
periment station for the individual application of 
scientific laws.
