I have not had an opportunity of comparing the teeth of this 
elephant with those of the HE. primogeneus. They resemble 
some of those figured by Parkinson. I will give you a drawing 
of one of the plates of the #. Jacksoni. (I will so call it for the 
sake of brevity.) This drawing is rather 
too wide, in proportion to the length. 
lines running obliquely, seven distinct 
ribands, and five which do not extend across the tooth. The 
other teeth differ from this, having more ribands which extend 
across the tooth, and only two which are broken. From these 
differences, we think that it cannot belong to the Z. primogeneus 
of Cuvier, and yet we are not prepared to say that it is identical 
with the H.. recens. 
I agree with you, that some other designation besides Waverly 
ought to be applied to the fine-grained sandstone. We ought to 
exclude all local names, And yet the term “ upper secondary” 
is objectionable, since this rock underlies all the coal, and is sepa- 
rated from the carboniferous limestone only by a bed of shale, 
three hundred feet thick. The term Waverly is used to designate 
a peculiar member of the secondary rocks, a particular stratum 
Which I have never seen elsewhere. It is composed of commi- 
' Huted sand, and yet it adheres so closely as to form the best build- 
ing material we have in the State. It is a rock sut generis. 
Dr. Hildreth, I suspect, must have arrived at the conclusion 
that the new red sandstone was found in Ohio, merely from the 
lithological characters of some of the rocks. _ The sandstones 
are occasionally tinged red, but this is local. For example, the 
Conglomerate, beneath all the coal, sometimes assumes this ap- 
pearance, and the Doctor was disposed to call it the new red sand-
