nguished by wanting all appendages to the head, either in the form
of crests or horns. The fifth type is, perhaps, the most extraordinary
of all; it should represent not only the order _Rasores_ among birds,
but also the _Camelopardalis_ among ruminating quadrupeds. Hence we find
that, in accordance with the first of these analogies, it is a peaceful
domesticated race, and that it has horns of an unusually large size,
even in its own group; while, at the same time, those horns have that
peculiar structure which can only be traced in the Camelopardalis; they
are covered with skin, which passes so imperceptibly to the horny state,
that, as Captain Clapperton observes, "there is no exact demarcation
where the one commences and the other ends." The five leading types of
quadrupeds and birds being now represented, and in precisely the same
order, _we demonstrate_ the groups to be natural by the following
table:--

GENUS _BOS_--_the Natural Types._

1. _Bos Scoticus._ Fierce, untameable. FERAE. RAPTORES.

2. ---- _Taurus._ Pre-eminently typical. PRIMATES. INCESSORES.

{Appendages on the head}
3. ---- _Dermaceros._ {greatly developed } UNGULATA. RASORES.

{Stature remarkably }
4. ---- _Pusio._ {small. } GLIRES. GRALLATORES.

{Fore-part of the shoulders}
5. ---- _Thersites._ {elevated } CETACEA. NATATORES.

In regard to the last type, the analogies can only be traced through
the animals or types of other groups; but should the habits of
_Thersites_ lead it to frequent the water (like the Buffaloes) more than
any other species of true oxen--a supposition highly probable--the
analogy to the _Cetacea_ and the _Natatores_ would be direct. When we
find in all the other four types such a surprising representation of the
same peculiarities, we are justified in believing that want of
information alone prevents this analogy from being so complete as the
others. These analogies, in point of fact, may be traced through the
whole of the principal groups in this order, the most important, and the
most numerous of ungulated animals." Our luminous classifier then
triumphantly winds up:--"_Having now demonstrated_, in one of the very
lowest groups of quadrupeds, the validity of those principles of natur
