CIRCULATION.
CHAPTER I.
OF THE ANATOMY OF THE MINUTE AND CAPILLARY
VESSELS.
All the descriptions of the minute and capillary
vessels and circulation which I have seen, contain
so many inaccurate statements, that they appear
to have been written from the imagination, rather
than from actual observation. As examples of
these inaccuracies, I may notice what is alleged

minute arteries, and of the immediate termination
of those arteries in veins, as they are observed in
the web of the frog. If such anastomoses and
terminations of the minute arteries do really exist
