Physiological Anatomy of the Lungs

                                might have been injected by these vessels in the most 
perfect manner: the process of thickening which 
the tissue has undergone in connection with the 
Bronchial artery will have obliterated nd blocked 
up the capillaries belonging to the Pulmonary vessels 
to such an extent that it will be found impossible 
to inject them fully - 
In the cellular tissue lying immediately beneath 
the Pleura, some veins of considerable size are 
to be seen, whenever the Bronchial artery has been 
fully injected. These veins are never distended 
by injection derived from the pulmonary vessels, 
however perfectly these latter only may have been injected 
throughout the lungs, and they never fail to become 
injected when the Bronchial arteries are so filled 
as to distend their capillaries. They return the 
blood collected from the sub-pleural cellular tissue 
and this blood is the residue of that sent to that 
structure by the Bronchial arteries and by none 
other.   a drawing of these veins (as seen by the 
naked eye and of the natural size) is shewn in 
Series B N<sup>o<\sup>5 and a representation of the same, as seen when magnified to 20 diameters is likewise 
shewn in Series B N<sup>o<\sup>6.
