218 APPENDIX. 



Figs. 5, 6, 7. — Anterior, posterior, and lateral views of a dentata, — not that of the great 

 skeleton, but of a cast of this vertebra in the Darmstadt Collection, which is so fine a specimen 

 that I thought best to represent it. 



PLATE XXII. 



Figs. 1, 2, 3. ■ — Anterior, posterior, and lateral views of one of the middle dorsal vertebrae. 

 Fig. 4. — The fourth, fifth, sixth, seventh, and eighth dorsal vertebra?, showing the attach- 

 ments of the ribs. 



Fig. 5. — The fifteenth, sixteenth, and seventeenth dorsal vertebras, with ribs attached. 

 Figs. 6, 7, 8. — Three views of two of the upper caudal vertebras. 



PLATE XXm. 



Fig. 1. — The second rib on the right side, showing the union of a fracture. 



Fig. 2. — Interior view of the sternal end of the same. This fracture is perfectly con- 

 solidated, and had existed perhaps three or four years. The newly formed bone is not so 

 exuberant as is sometimes seen in fractures. 



Fig. 3. — A portion of the spinal column with the ribs attached, in connection with the 

 pelvis ; showing a fracture of the nineteenth and twentieth ribs, with exuberant new bone effused 

 between, and cementing them firmly together. This fracture establishes with certainty the 

 existence of a twentieth rib in Mastodon Giganteus ; a fact which cannot be settled in the other 

 Mastodon skeletons on account of their imperfection. 



Fig. 4. — View of these two ribs from above. 



Fig. 5. — Interior view of the right scapula ; the epiphysis wanting, but its situation indi- 

 cated by a dotted line. 



PLATE XXIV. 



Figs. 1, 2, 3. — Anterior, posterior, and lateral views of the pelvis. 



PLATE XXV. 



Fig. 1. — Anterior view of the right fore-leg and scapula. 

 Fig. 2. — Posterior view of the same.
