n thousand diameters, or forty-nine million
times in surface. When we can make the forty-nine millionth of a second
as long as its integer, physiology and chemistry will approach nearer the
completeness of anatomy.

Our reverence becomes more worthy, or, if you will, less unworthy of its
Infinite Object in proportion as our intelligence is lifted and expanded
to a higher and broader understanding of the Divine methods of action.
If Galen called his heathen readers to admire, the power, the wisdom, the
providence, the goodness of the "Framer of the animal body,"--if Mr.
Boyle, the student of nature, as Addison and that friend of his who had
known him for forty years tell us, never uttered the name of the Supreme
Being without making a distinct pause in his speech, in token of his
devout recognition of its awful meaning,--surely we, who inherit the
accumulated wisdom of nearly two hundred years since the time of the
British philosopher, and of almost two thousand since the Greek
physician, may well lift our thoughts from the works we study to their
great Artificer. These wonderful discoveries which we owe to that mighty
little instrument, the telescope of the inner firmament with all its
included worlds; these simple formulae by which we condense the
observations of a generation in a single axiom; these logical analyses by
which we fence out the ignorance we cannot reclaim, and fix the limits of
our knowledge,--all lead us up to the inspiration of the Almighty, which
gives understanding to the world's great teachers. To fear science or
knowledge, lest it disturb our old beliefs, is to fear the influx of the
Divine wisdom into the souls of our fellow-men; for what is science but
the piecemeal revelation,--uncovering,--of the plan of creation, by the
agency of those chosen prophets of nature whom God has illuminated from
the central light of truth for that single purpose?

The studies which we have glanced at are preliminary in your education to
the practical arts which make use of them,--the arts of healing,--surgery
and medicine. The more you examine the structure of the organs and the
laws of life, the more you will find how resolutely each of the
cell-republics which make up the E pluribus unum of the body maintains
its independence. Guard it, feed it, air it, warm it, exercise or rest
it properly, and the working elements will do their best to keep well or
to get well. What do we do with ailing vegetables? Dr. Warren,
