processes each bearing on its upper edge a high rounded immured lobe - between these lobes is a deep, horseshoe shaped opening. The sternum articulates to its distal ends of its first pair of ribs - the ends of their fit cut to the angles formed by the lower sides of the transverse processes and the ventral spin or process. The end of the rib is 50 mil. from the side of the central process - due to the sternum and the upper side of its distal end of the rib is 20 mil. from the lower edge of the transverse processes. (Their measurements were taken shortly after the whole was rib was taken apart of the whole) The rib is tipped with carti- ilage, but articulation to the sternum is by ligaments & not by cartilage as in the Hemipack. sternum greatest breadth = 550 mil. " " height = 490 " The first rib is flat for its entire length & strongly curved having a single pointed head, a long slender neck, & a tubercle - rib is widest at its distal end Rib Length straight (tubercle to end) = 983 mil. Curved (circ.) = 11/4 mil. Breadth at distal end (greatest): 150 " Scapula The acromion & coracoid project almost straight anterad Height (q. fossa to edge) = 650 mil. Length acromion from edge] = 260 mil. Breadth " " glenoid fossa = 1/10 " = 220 " Length coracoid: 160
