PLATE 3 
EXPLANATION OF FIGURES 
8 Approximately dorsal view of right humerus, showing its broad lateral 
expansion and the surface for articulation with the coracoclavicle, Ch; with the 
seapula, f; with the radius, ¢, and with the ulna, ¢r. 
9 Approximately anteromedian view of right humerus showing its relation- 
ship to the forearm (fig. 13), and the scapula (fig. 11). The dotted line from 
the capitulum humeri, ¢, to the fovea capituli radii and incisura semilunaris of 
figure 13 indicates the point of union at the elbow-joint. The dotted line from 
the facies articularis scapulae, f, to the cavitas glenoidalis, Cg of figure 11, indi- 
cates the union of the humerus with the scapula. Figures 9, 11, and 13 are each 
drawn from practically the same point of view. 
10 An approximately ventral view of the right humerus. The two dotted 
lines from the capitulum humeri, ¢, and the trochlea humeri, tr, to the fovea cap- 
ituli radii, fr, and the incisura semilunaris, 7s, of figure 14 indicate the points of 
junction of these bones at the elbow-joint. The proximal end of the humerus 
would have to be lifted up until the figure made almost right angles with the 
paper and the figure 14 to give the normal relative position of these bones. 
11 Anterodorsal view of the scapula. 
12 Lateral view of the scapula. 
13. Anteromedian view of the ulna, radius, and manus. 
14 Ventral view of the ulna, radius, and manus.
