                                =sentations of the air channels which exist in 
the long bones of birds - 
Whether these channels in the Pleura transmit 
air only, or whether they transmit Bronchial 
mucus, or whether they are in some way annex=
=ed with the Lymphatic system may <s>possibly<\s> perhaps be 
a matter of doubt, but no doubt exists or can 
by any possibility arise that the function they 
discharge belongs exclusively to the process of 
Respiration, since the fact that they derive their 
blood from the Pulmonary system and not from 
the Bronchial, leaves no possibility of a question 
on that head - 
The costal Pleura in like manner derives its 
supply of blood from the pulmonary vessels; about 
eight or ten arteries of considerable size, deriv=
=ed from the pulmonary artery and about twelve 
or sixteen corresponding veins of some magnitude 
cross behind that fold of the Pleura (which some=
=times goes by the name of the broad ligament) 
to reach the Thoracic pleura and to become dis=
=tributed upon it; imparting therefore to that 
structure also properties auxiliary to the process 
of Respiration -
