_Circulation of the Blood._--About twenty-five years since, being in a
public library in France, a learned physician pointed out to me in the
works of the Venerable Bede a passage in which the fact of the circulation
of the blood appeared to him and myself to be clearly stated. I regret that
I did not, at the time, "make a note of it," and that I cannot now refer to
it, not having access to a copy of Bede: and I now mention it in hopes that
some of your correspondents may think it worth while to make it a subject
of research.
