Physiological Anatomy of the Lungs

                                it would be requisite that hose nerves should be at 
least as extensive as those of the remainder of the 
body, since it is obvious that the vital changes which 
are wrought in the lungs, <s>it would be requisite that 
those nerves<\s> are precisely equal in extent to the correlative 
operations which take place in the remainder of the 
body considered in the aggregate. 
Moreover if those nerves did in truth manufacture 
that vital force it is clear that some materials would 
have to be supplied to those nerves out of which 
it could make that commodity: 'Ex nihilo nihil 
fit', there are no such materials furnished 
to the pulmonary plexus - 
It is obvious to common sense, that just so much 
contractile power as it is necessary that the various 
parts of the lungs should enjoy, that just so much 
sensation as it is requisite that they should be 
endowed with may be regulated and brought into 
harmony with similar states of other portions of the 
body associated in the mechanical part of the function 
of breathing and that these coordinating effects may be brought about 
through the instrumentality of the nerves of the Pulmo=
=nary Plexus, but it is utterly preposterous and im=
=possible that the plexus or its nerves can manufacture
