14. Head of the Mastodon Giganteum. 

 To Prof. Silliman. — Bear Sir — Enclosed I send you a profile 

 view of the head of the Mastodon Giganteum. The specimen from 

 which the drawing is taken, was brought to light during the year 

 1838, in excavating a mill-race on the land of Mr. Hahn, near Bucyrus, 

 Crawford County, Ohio, and is believed to be the most perfect one 

 which has yet been discovered. We are thus enabled to complete the 

 skeleton of this gigantic quadruped, the remains of which are so 

 abundant throughout the western country. 



Other portions of the skeleton were also exhumed. They were, ac- 

 cording to Mr. Briggs,* as follows : 



Head. — The entire head, with the exception of the tusks. 



^'•VertehrcR. — 6 Cervical ; 6 Dorsal ; 1 Lumbar; 5 Caudal. 



Ribs. — 28; 12 entire. 



Pelvis. — The sacrum and the whole of the left side, and the ossa 

 pubis, and part of the ossa ischium of the right side. 



Extremities. — 1 Os-femoris ; 1 Tibia ; 1 Fibula ; 1 Radius ; 1 Ulna ; 

 2 Patellae ; 11 Bones of the feet." 



I am also indebted to the same source for the measurements of the 

 head and under jaw.
