eo 
yation of the bones, the completeness of the skeleton, and perhaps 
its size, this is the most perfect which has yet been discovered. The 
bones contain a large portion of their gelatine, are firm in texture, light 
in color, and sonorous when struck. The number of bones found is 
sufficient to complete the skeleton with very slight exceptions, and to 
give a true idea of the osseous fabric of the animal. Some of the 
caudal vertebrae and a few bones of the feet only are missing, but 
those wanting in one foot exist in the other, both in the anterior and 
posterior extremity. As to size, its actual height cannot at present be 
stated with precision ; the length of the head however is three feet, 
and the breadth of the pelvis six feet. The tusks when discovered 
were ten feet long; but a portion about four feet in length only of 
each tusk is well preserved : of the remainder, about four feet retains 
its form, the rest is decomposed. Avery interesting fact in this spe- 
cimen is the existence of an incisor tooth, or tusk, in the lower jaw on 
the left side, and the traces of the socket of another on the right. 
This magnificent relic of a lost race is now insured to our country 
and its scientific resources, by having become the property of Dr. John 
C. Warren of Boston, Professor of Anatomy, &c. in Harvard Univer- 
sity. The skeleton has been taken to pieces, and is now in process of 
re-articulation with the aid of all the light of comparative anatomy de- 
rived from scientific men, and from the skeletons of the elephant, tapir, 
and other pachydermatous animals. Every effort will be made, we 
are informed, to place the different parts in a strictly anatomical rela- 
tion, and without any attempt to exaggerate the surprising dimensions 
of the animal. When set up, and protected from decomposition, it 
will be open to the inspection of men of science of this and foreign 
countries. 
It is a little remarkable, that in the summer of 1844 a mastodon 
skeleton was discovered in New Jersey, which was at the period of 
its discovery more perfect than any other. The whole number of 
articulated mastodon skeletons which previously existed, was, we be- 
lieve, only three, viz. Mr. Peale’s in Philadelphia, and that in Balti- 
more, found in Newburg in 1802, and Dr. Koch’s Missourium, in the 
British Museum, found in 1840. That of New Jersey was much 
more complete than those just mentioned ; but it wanted entirely the 
bones of the feet. 
The whole of this skeleton, however, is in excellent preservation ; 
the bones are of a dark color, as the mastodon bones usually are, being 
impregnated with the oxide of iron, which no doubt has aided in their 
ervation. The tusks are perfect and short; a fact, which together 
with the aperture of the pelvis compared with its whole breadth, which 
is four feet ten inchés, supports the opinion of its being a female. It 
had no tusk in the lower jaw, nor any vestige of their previous existence.
