Description of an entire Head and various other Bones of the Mastodon. By 

 William E. Horner, M. D., and Isaac Hays, M. D. Read October 2, 1840. 



The undersigned, a committee appointed by the Society, January 3d, 1840, 

 to report a description of the collection of Mastodon bones recently presented 

 to the Society by some of its members, have the honour to submit the follow- 

 ing account : 



According to the statement of Mr. D. Wood, from whom these bones were 

 purchased, they were discovered two years since about seven feet below the 

 surface of the ground, in digging a mill-race on the estate of Abraham Halm, 

 three-fourths of a mile east of Bucyrus, Crawford County, Ohio, on the dividing- 

 ridge between the Sandusky and Sciota valleys. This ridge, consisting of 

 table land, is one of the highest elevations in Ohio, is well cultivated, and 

 abounds in never-failing springs, which constitute the sources of the Sandusky 

 and Sciota rivers. The waters of the former flow into Lake Erie by a course 

 almost due North, and those of the latter, into the Ohio, by a course nearly 

 due South. The soil in which the bones were buried is entirely alluvial. 



The collection contains portions of the skeletons of two animals, one 

 larger than the other. The bones of the larger of these animals are lighter, 

 more worn, more decomposed, and larger in their specific measurements than 

 the other, and are of a different colour. All these bones were sold as common to 

 one skeleton, but that they appertained to different individuals is sufficiently 

 substantiated from what is alleged; and, moreover, by some of the carpal bones 

 of the right side being in duplicate. Whether or not all were really exhumed 

 from the same spot cannot now be ascertained by the committee.
