at Niagara, in a modern alluvial, in which, however, were 
found fluviatile shells of existing species. 
© From all the facts adduced, it will not be questioned that 
the remains of the mastodon do occur in situations proving 
their existence upon the surface subsequent to the period 
when it has undergone any great change. Or, in other words, 
the surface of our globe had arrived at its present condition, 
essentially, at the period of the existence of the mastodon and 
other animals whose remains are associated with it. Now 
although the specimen in question was not found associated 
with remains of this kind, yet the deposit in which it occurs 
is of the same age, and the shells are of existing species. We 
might be willing to admit its existence without this attempt at 
proof, but it is still desirable to establish, beyond doubt, the fact. 
The only fossil bones of a similar animal before known, are 
the lower jaw, together with the upper incisor and the radius. 
These bones were found with those of the mastodon, in the 
bottom of a peat swamp in Ohio, at the depth of fourteen feet 
from the surface, resting on a bed of pebbles and gravel, a 
they are represented as considerably worn by attrition before 
their deposition. Their position being upon the surface of these 
drifted matters, even were that deposit the older drift, would 
not prove them coéval, since they are preserved in the “ care 
bonaceous mud," which was evidently a quiet deposition 1n 
the shallow basin, made long after the coarser materials at the 
bottom had been deposited. At the same locality, (two miles 
north of Nashport, between the Muskingum and Licking val- 
leys, on Wakitomika creek,) were found also the bones of @ 
ruminant animal, at the depth of eight feet from the surface. 
This was in all probability coéxistent with the animal in ques- 
tion and the mastodon. 
The discovery of this relic has added a very interesting 
species to the ancient Fauna of the state of New York, of 
which we before possessed only the remains of the mastodon, 
the elephant, and possibly a deer, a jawbone and teeth of 
last animal having been found in a swamp, with the bones of 
the mastodon, in Greenville, Greene county, New York.
