contrast to his brother William, who was a fluent and brilliant
speaker. Hunter's lectures were at best simple readings of the
facts as he had written them, the diffident teacher seldom
raising his eyes from his manuscript and rarely stopping until
his complete lecture had been read through. His lectures were,
therefore, instructive rather than interesting, as he used
infinite care in preparing them; but appearing before his classes
was so dreaded by him that he is said to have been in the habit
of taking a half-drachm of laudanum before each lecture to nerve
him for the ordeal. One is led to wonder by what name he shall
designate that quality of mind that renders a bold and fearless
surgeon like Hunter, who is undaunted in the face of hazardous
and dangerous operations, a stumbling, halting, and "frightened"
speaker before a little band of, at most, thirty young medical
students. And yet this same thing is not unfrequently seen among
the boldest surgeons.


Hunter's Operation for the Cure of Aneurisms

It should be an object-lesson to those who, ignorantly or
otherwise, preach against the painless vivisection as practised
to-day, that by the sacrifice of a single deer in the cause of
science Hunter discovered a fact in physiology that has been the
means of saving thousands of human lives and thousands of human
bodies from needless mutilation. We refer to the discovery of the
"collateral circulation" of the blood, which led, among other
things, to Hunter's successful operation upon aneurisms.

Simply stated, every organ or muscle of the body is supplied by
