 molar teeth. The tubercles of the crowns of the teeth were 

 but little worn, showing, together with the absence of the third

 maturity. The dimensions of the teeth were not extraordinary 

 for proboscideans, being from two inches to four or five inches in 

 antero-posterior diameter along the crowns, while the third mo- 

 lar of an adult Mastodon ranges from 1£ to 8J inches in the 

 same dimension. These interesting relics of a former age and 

 a former population, are retained in the hands of their discov- 

 erer. It is greatly to be hoped that he will not allow them to 

 become scattered or destroyed. 



During the progress of the former survey, a large vertebra 

 was discovered in the western part of the State which was 

 recognized at the time as the caudal vertebra of a whale, by 

 Prof. Sager, then State Zoologist.
