FIG. 12. The Left Pleural Chamber opened up by the removal of its lateral 

 wall. The lung has been taken away and a " window " has been made 

 into the superior mediastinum by the removal of a portion of the medias- 

 tinal pleura. Several of the structures which form the mediastinal 

 partition are seen shining through the mediastinal pleura which is in situ.
