THE BALTIMORE TOOTH. 85 



example, seen one or two bones of Mastodon Gigantens deeply buried in 

 Connecticut, and a number of bones of Elephas Primigenius in the hills of 

 Vermont. 



While, however, the Baltimore tooth resembles in many respects the 

 Humboldtian, it differs in size ; some of those of the latter, which I have 

 seen, being very large. But my experience on this point is too limited 

 to allow me to place much stress on it ; and, moreover, difference in magni- 

 tude is not a safe ground for specific distinctions. Whether correct or not, 

 this is the best opinion we are able to give in regard to the character 

 of this tooth. 



There are, therefore, objections to placing it in the species Humboldtius, New 



Species. 



which may be removed by considering it a new species ; and I leave the 

 learned to determine whether it deserves this distinction.
