in different parts of the same jaw.” It is interesting to. know that the 
geographical range of this animal has been carriedso far east as the 
Santee. canal in South Carolina, from whence the teeth and portions 
of the jaw, figured by Prof. Gibbes, were taken, being imbeded in ” 
green sand marl. 
With regard to the skeleton exhibited by Mr. Koch as the Slgdeneiens 
Dr. Wyman concludes, Ist, that these remains have never belonged to 
one and the same individual ; 2d, that the anatomical character of the 
teeth indicates that they are not those of a reptile, but of a warm-blood- 
ed mammal. It is worth mentioning, as an instance of the accuracy 
and skill of the joiner of the Hydrarchos, that the extremities of the 
so called paddles of this skeleton, were formed of “ casts of a came- 
rated shell, a species of nautilus”! of which, specimens, brought 
from the state of Alabama, and now in the cabinet of the Academy of 
Natural Sciences, were shown to Prof. ,Wyman, by Dr. Morton of Phil- 
adelphia.* 
2. Mastodon Giganteus. —The publication of Prof. Owen’s “ British 
Fossil Mammalia and Birds,” has supplied us with the means of pre- 
senting our readers witha most perfect and elaborate portrait of the 
fine specimen of this animal, which is now standing in the British 
Museum. Mr. Owen says, (p. 298,) ‘ The almost complete — 
of the Mastodon giganteus, so well known to the public as the 
souri Leviathan,” when exhibited, with a most grotesquely pinea 
and exaggerated collection of the bones in 1842 and 1843 in the Egyp- 
tian Hall, Piccadilly, but now mounted in strict accordance with its 
natural proportions, in the British Museum, has enabled me to present, 
in the subjoined cut, (see next page,) as perfect a representation of the 
mastodon, as that of ~ mammoth given at the head of the prennyrs 
section.” 
mH is recurved more than one application from respectable persons, unac- 
quainted with comparative anatomy, to express an opinion as to the character of 
Koch's Hydrarchos, we will only say, that if the foregoing remarks, the testimony 
of one of the best comparative anatomists in America; the evidence 0 aa Mr. Lyell 
and Mr. Houston, (vol. i, p. 213) and of Dr. Lister; (Proceedings 
Hist, Feb. 26, p. 94) are not sufficient to convince the most credulous cht the ficti- 
tious sherneisa of this skeleton, perhaps their faith in the skill of the joiner may be 
enlightened by a perusal of the following note on the mastodon. It is certainly not 
impossible that a Zeuglodon may be found 114 feet long ; but if aera by 
the same inventor, we might aswell expect to see it 300 feet in len 
t Those who saw the “ grotesquely distorted” monster, thick was Rakew wn by 
Mr. Koch in this country, as s the Missourium or Leviathan, will hardly recognize 
in the beautiful drawing on the next page, the same animal as restored by the 
accurate hand of Owen. The large lithographic print of the animal as mounted 
by Koch, which his ogling ecuted at Dresden, will serve to convey to
