EXPLANATION OF PLATES I.-III. 
Fig. 1. Vertebral column of anorchid subject A 9. To show the unusual curva- 
tures of the column. The upper part of the lumbar curve is flattened out. The 
thoracic portion of the column is nearly straight below ; slightly convex forwards 
above. The cervical portion is straight and vertical. 
Fig. 2. Sagittal section of the 11th thoracic vertebra of A 9. To show the 
wedge-shaped body, with its markedly greater depth behind. 
Fig. 3. The clavicles of A 9, to show their great breadth at the acromial end. 
Fig. 4. A. The skeleton of C 5 (after Becker). B. Photograph of subject A 10. 
These are placed side by side to show the difference between the “ early” and 
“ intermediate late ” types of anorchid body form. It is interesting to note that 
though the shoulders of the two subjects are on approximately the same level, the 
centre of the pelvic inlet of C 5 is on the same level as the umbilicus of A 10. 
Fig. 5. Skull of A 10. To show the small size of the bodies of the superior 
maxillaries. 
Fig. 6. Atlas and axis vertebrae of A 10. To show the misfit of their 
articulating surfaces.
