SYMPATHETIC NERVES OF THE TERRESTRIAL CARNIVORA. 



71 



Anterior Pulmonary Nerves (text-figs. 4, A.P.P.-ll, A'.P'.P'.) 

 arise from the vagi anterior to the pulmonary roots, or as bifur- 

 cations from cardio-pulnionary branches. 



Posterior Pulmonm'y Nerves (text-figs. 4, g.g.-W^ 9-9' ■), which 

 are two to four in number, arise from the vagi as they run along 

 the dorsal surfaces of the roots of the lungs. They may be very 

 short and minute, or long and thick. 



Plexus Gulce (text-figs. 4-11): — Between the ]'oots of the lungs 

 and the diaphragm there is a more or less intricate anastomosis 

 between the vagi across the cesophagus. There may be only

branches of communication, bvit in most forms there is a mingling 

 of divisions of the vagi. From the plexus two cords emerge ; one 

 runs through the ventral aspect of the oesophageal orifice in the 

 diaphragm and tlie other through its dorsal aspect. The arrange- 

 ments observed by me were : —
