great men were actually received by the medical
profession.

In 1628, Harvey published his first work upon the circulation. His
doctrines were a complete revolution of the prevailing opinions of all
antiquity. They immediately found both champions and opponents; of
which last, one only, Riolanus, seemed to Harvey worthy of an answer, on
account of his "rank, fame, and learning." Controversy in science, as in
religion, was not, in those days, carried on with all the courtesy which
our present habits demand, and it is possible that some hard words may
have been applied to Harvey, as it is very certain that he used the most
contemptuous expressions towards others.

Harvey declares in his second letter to Riolanus, "Since the first
discovery of the circulation, hardly a day, or a moment, has passed
without my hearing it both well and ill spoken of; some attack it with
great hostility, others defend it with high encomiums; one party believe
that I have abundantly proved the truth of the doctrine against all
the weight of opposing arguments, by experiments, observations, and
dissections; others think it not yet sufficiently cleared up, and free
from objections." Two really eminent Professors, Plempius of Louvain,
and Walaeus of Leyden, were among its early advocates.

The opinions sanctioned by the authority of long ages, and the names of
Hippocrates and Galen, dissolved away, gradually, but certainly, before
the demonstrations of Harvey. Twenty-four years after the publication of
his first work, and six years before his death, his bust in marble
was placed in the Hall of the College of Physicians, with a suitable
inscription recording his discoveries.

Two years after this he was unanimously invited to accept the Presidency
of that body; and he lived to see his doctrine established, and all
reputable opposition withdrawn.

There were many circumstances connected with the discovery of Dr. Jenner
which were of a nature to excite repugnance and opposition. The practice
of inoculation for the small-pox had already disarmed that disease of
many of its terrors. The introduction of a contagious disease from a
brute creature into the human system naturally struck the public mind
with a sensation of disgust and apprehension, and a part of the medical
public may have shared these feelings. I find that Jenner's discovery of
vaccination was made public in June, 1798. In July of the same year the
celebrated surgeon, Mr. Cline, vacc
