by the pulmonary veins to the left auricle of the heart.
A drawing of this plexus is seen in series C No 5 fig a,
and the ramusculi, which collect the blood from it,
and pass it into the trunks of the pulmonary veins -
are delineated in the same drawing in fig. b.
These ramusculi are situated on the external sur=
=face of the Bronchial tubes - The plexus lining
the mucous membrane is obviously a sort of diverti=
=culum from the main current, by which the arte=
=rialized blood is returned to the left auricle
and is quite distinct and independent of any
anastomosis whatever; it forms a much more
vascular layer over the mucous membrane than
can at all be attributed to to the Bronchial vessels,
and it may be fairly a matter of doubt whether,
if the whole of the Bronchial arteries were exclusively
confined to this plexus and had no other distribution,
they would be large enough to supply an equally vas=
=cular distribution to it - But it has been con=
=clusively shewn that the Bronchial arteries are spread
out in a very uniform manner to every part of
the lungs; its principal distribution being to the
fibrous tissue of the leaflets and of the Bronchial tubes
