in other words, throughout the closed door season. In early days malaria 
dominated everything; there was comparatively little other sickness. Agri- 
cultural communities as a rule were healthy if there was no malaria about. 
Today false malaria dominates wherever people are massed, as indicated in 
my cases for 1906. The student who desires to study malaria will find little 
opportunity in Indiana today. I have not seen a case for about thirteen 
years. But for material for a study of False Malaria Indiana can not be 
excelled. 
Just as malaria has disappeared by cleaning up the breeding places of the 
rural anopheles mosquito, so false malaria will also disappear when we begin 
to clean up generally, when we get clean air to breathe. When once an 
overgrown town begins to bevsone a real c.ty by putt ng in sewers, paved 
streets, getting fltered water and a clean high school, a so‘t of civic center, 
you can readily see why people become less tolerant of the chewer and 
spitter and in time of the smoker. The smoker, it should be noted, is usually 
also a spitter. 
If I had time I should like to review briefly several medical papers in 
which I developed the theory of dust infection or coniosis, and show how one 
can distinguish between other affections and diseases. One ean treat the 
subject from two viewpoints, medical and biological. Medically, coniosis 
can be considered as a disease; biologically, coniosis is a reaction. Regard 
it as a disease and at once there come to mind treatment, medicine, remedy, 
eure. Regard it as a reaction, then naturally there comes to mind preven- 
tion. From the physicians’ standpoint, there are two classes of people, 
those who Take Something and those who Do Something. Some when 
feeling bad will take all sorts of drugs, including tobaeco and alcohol. Others 
will take a change of environment, of occupation, or of residence. The 
latter are the wise; there will be more of these when the relationship of 
cause and effect is once properly understood. 
The second viewpoint, the biological, is to regard coniosis or false malaria 
as a reaction. Now how ean a reaction be cured in the constant presence 
of a cause? Why are there so many isms and pathies, so many pseudo 
remedies and new ones constantly arising? Looked at in this light you 
knock the props out from under the patent medicine man and the symptom- 
prescribing doctor and quack.
