tomose with the network already described. Just mesial to the termi- 
nation of the incisura interlobaris a very prominent branch can be seen 
in Fig. 5 which comes from the depth of the lung. 
Fig. 6 shows a combination drawing of three consecutive sections taken 
perpendicular to the pleura. A branch of the bronchial artery can be seen 
Fie. 6. Lung of the sheep. Combination of three successive sections taken 
perpendicular to the pleura. B. = bronchus in the wall of which sections cof 
the bronchial artery are seen. B. =a branch of B which here runs a short 
distance beneath the surface. B. A. = bronchial artery. P. = pleura. P. A.

following a bronchus and one of its branches, which here runs a short 
distance beneath the pleura, then, leaving the bronchus, it joins the 
network of vessels derived from the branches of the bronchial artery which 
pass directly to the pleura. 
The vascular network about the lymphatics in the sheep’s pleura is
