146 Dr. J. C. Warren on the Osteology and Dentition of 



leton of another Mastodon giganteus had been discovered in the 

 town of Newburgh, State of New York^ about six miles from the 

 bank of the Hudson river (in the same town^ but not on the same 

 spot, from which the skeleton set up by Mr. Peale was obtained 

 in the beginning of this century), and that it was in every respect 

 more perfect, and perhaps larger than any one yet found. It is 

 worthy of remark, that of five existing specimens of Mastodon, 

 three have been exhumed in the contiguous States of New York 

 and New Jersey ; two of them from the same town. Only two or 

 three Mastodon bones have been discovered in any part of New 

 England. The Baltimore skeleton was excavated in the State of 

 Ohio, and the Missourium of the British Museum from the State 

 of Missouri. 



After the specimen from Newburgh had been articulated, it 

 was exhibited in the city of New York during the past autumn, 

 and was subsequently brought to the vicinity of Boston by the 

 proprietor, Mr. Brewster. Having satisfied myself of the per- 

 fection and the great value of the bones, with a view to the promo- 

 tion of science and from a conviction of the great injuiy which 

 would be done to the skeleton by public exhibition in various 

 places, I made offers for its purchase, which were accepted. This 

 invaluable specimen is now my property, and as a duty to sci- 

 entific men who are interested in the subject, I shall feel myself 

 called on to describe it particularly at a future time in connexion 

 with the New Jersey skeleton. 



As the bones were articulated in a manner different from what 

 seemed to me exact, I have had them separated with a view to a 

 new arrangement, founded on the strictest anatomical observa- 

 tion. The skeleton appears to be about twelve feet high, and 

 some idea of the size of its parts may be formed from the fact, 

 that the head is three feet long without the tusks, which were 

 ten feet in length. These dimensions have, however, diminished 

 since the bones were first exposed to the air ; the pelvis, for ex- 

 ample, which measured six feet two inches at first in its transverse 

 diameter, now measures six feet. The comparative length of the 

 tusks and of the diameters of the pelvic apertures are characters 

 from which I have inferred the New Jersey specimen to have been 

 a female, and my own very probably a male. 



The whole head with its teeth is perfect, as is the whole ver- 

 tebral column, consisting of seven cervical vertebrae, twenty dor- 

 sal, three lumbar, and the os sacrum. A solid sternum exists, 

 the posterior part of it only being deficient. The ribs, twenty in 

 number, are perfect. The bones of the pelvis are co-ossified, — a 

 fact which would lead to the suspicion of the animal having been 

 aged ; but on the other hand, the epiphyses, although co-ossified 

 with their bones, yet generally exhibit traces of separation. The
