The Atlantic Seaboard


after similar researches in Europe, it was a noteworthy contribution
that has been widely cited.

   We have in Baltimore and in Boston examples of the important
emphases in the early development of bacteriology in the United States.
At Johns Hopkins, the individual aspects of infectious diseases, their
history, pathology, and their causative agents were stressed. In Boston,
with the remarkably active State Board of Health tying in with both
the Massachusetts Institute of Technology and Harvard University,
we find the public health aspects of bacteriology receiving the greater
emphasis. Especially through the studies at the Lawrence Experiment
Station, methods were developed for large-scale purification of sewage
and also for the filtration of polluted waters, thus making our crowded
industrial cities possible without a high enteric disease rate. As we
travel south and later west on our bacteriologic journeys, we shall find
other types of studies that have proved of inestimable value to society.
Of necessity I must choose only a few examples from our broad conti-
nent with its diverse backgrounds.
