EDUCATING ADMINISTRATORS AND CLINICIANS

development and change are his anathema. He must design experiments
so that a relatively few samples will be significant. It is not only the
administrator and clinician who sometimes must be educated in this, but
also the ambitious beginner in electron microscopy who must learn to
limit his objectives and define them carefully.
Electron microscopy received widespread publicity in its early stages,
and undoubtedly many people were naively led to expect too much. It
has its limitations! In essence one must pay for magnification by accepting
a restriction of field and all that this implies. One cannot do conventional
histology with an electron microscope any more than one can do gross
anatomy with a light microscope. The world of the electron microscope
is a world that could only be studied inferentially before. It is a vastly
important world and we should hardly have to defend its exploration
with the most effective tool to date. The flea scurries about and his whole
world is less than one square yard of a dog. The electron microscopist
can be very busy too, and in his whole lifetime not cover as much
territory.
