and five tibiae. Some of these are almost entire ; others are much 

 mutilated. 



It is necessary to observe, that although these large bones, as 

 well as the detached tusks, have all been provisionally referred 

 to the Mastodon, yet it is not improbable that on a further com- 

 parison, a part may be found to belong to the fossil elephant. 

 The mutilated condition of some, renders it extremelv difficult to 

 pronounce with certainty upon a slight examination. 



The remains of the fossil elephant comprised in this collection, 

 are next in interest and number, to those of the mastodon. 



The first that we shall notice, is the head of a young individual, 

 more complete than any known to your committee to have been, 

 as yet, obtained in North America. It consists of the upper and 

 lower maxillary bones, with six molar teeth in good preserva- 

 tion. Isolated grinders of the elephant have been discovered in 

 the United States in numerous instances, but generally without 

 any portion of bone adhering to them. There are also of the 

 elephant in this collection, several other large fragments of jaws, 

 and twenty separate molar teeth. 



Of the horse, there are perfect teeth, and other portions, found 

 under circumstances that favour the belief of their being of equal 

 antiquity with the extinct animals whose remains are associated 

 with them in the collection. The teeth are remarkably large 

 and sound. 



Of ruminating animals, there are skulls and other parts of the 

 Buffalo, Bos Americanus ; of the extinct species named by Dr. 

 Harlan, Bos bombifrons ; and of a large species of Cervus, resem- 

 bling C. alces. 



Finally, we have also discovered among these interesting relics, 

 some considerable portions of the megalonyx, whose osteology is 

 still so imperfectly known. The most important of these is a 

 right lower maxillary bone, with four teeth in the socket, and 

 another detached tooth which appears to have come from the 

 upper jaw. There is also a tibia of the right leg, and perhaps 

 some other bones which may prove to belong to the same animal. 



Mr. Cooper^s Denial. — Mr. G)oper has requested us to state, 

 that he never expressed the opinion attributed to him in the 

 American Journal of Science and Arts, for April, 1831, respect-
