possibility of any honest or sincere dispute that
the pulmonary vessels are engaged exclusively
in the respiratory process, and that the Bronchial
vessels fulfil the purpose of restoring and repairing
the tissue of the lungs and their appendages,
without any assistance or anastomosis from the
Pulmonary vessels.
Longitu=
=dinal
channels
The second point to be observed in connection
with the Pleura, consists in the fact that certain
longitudinal channels of a remarkable character
exist in it. These channels somewhat resemble
the sinuses of the Dura Mater of the brain, but
they differ from them in the circumstance that they
are quite colourless and that if they transmit any
fluid through them, that also is destitute of colour.
Tubular
passages
These channels are in connection by means of
certain tubular passages, running through the
sub-pleura cellular tissue, with a number of fora=

lungs, and upon the interlobular surfaces also: these
Foramina
foramina, however, can only be seen when the
Pleura and subpleural cellular tissue has been
stripped off from the surface of the lungs and
are always situated in the sulcus, which separates
