. ' PLATE V 



Plate V is from a section through the intervertebral 

 disc (Fibrocartilago intervertebralis I) between the first 

 and second thoracic vertebrae posteriorly, through the 

 inner third of the clavicles anteriorly, and through the lovsrer 

 part of the glenoid cavities of the scapulae laterally. The 

 plane of the section is 1.7 cm. anteriorly and 1.1 cm. pos- 

 teriorly below section IV, hence the anterior margin is 3.2 

 cm. lower than the posterior. 



The axillary veins are not cut except where other veins 

 open into them, but each is easily traced at the surface of 

 the section, and is indicated in the plate by dotted lines.
