The orang-outang perfectly resembles man both in the order and number of
his teeth. The orang-outang is the most anthropomorphous of the ape
tribe, all of which are strictly frugivorous. There is no other species
of animals, which live on different food, in which this analogy exists.
(Cuvier, "Lecons d'Anat. Comp". tom. 3, pages 169, 373, 448, 465, 480.
Rees's "Cyclopaedia", article Man. ) In many frugivorous animals, the
canine teeth are more pointed and distinct than those of man. The
resemblance also of the human stomach to that of the orang-outang is
greater than to that of any other animal.

The intestines are also identical with those of herbivorous animals,
which present a larger surface for absorption and have ample and
cellulated colons. The caecum also, though short, is larger than that of
carnivorous animals; and even here the orang-outang retains its
accustomed similarity.

The structure of the human frame, then, is that of one fitted to a pure
vegetable diet, in every essential particular. It is true that the
reluctance to abstain from animal food, in those who have been long
accustomed to its stimulus, is so great in some persons of weak minds as
to be scarcely overcome; but this is far from bringing any argument in
its favour. A lamb, which was fed for some time on flesh by a ship's
crew, refused its natural diet at the end of the voyage.
There are
numerous instances of horses, sheep, oxen, and even wood-pigeons, having
been taught to live upon flesh, until they have loathed their natural
aliment. Young children evidently prefer pastry, oranges, apples, and
other fruit, to the flesh of animals; until, by the gradual depravation
of the digestive organs, the free use of vegetables has for a time
produced serious inconveniences; FOR A TIME, I say, since there never
was an instance wherein a change from spirituous liquors and animal food
to vegetables and pure water has failed ultimately to invigorate the
body, by rendering its juices bland and consentaneous, and to restore to
the mind that cheerfulness and elasticity which not one in fifty
possesses on the present system. A love of strong liquors is also with
difficulty taught to infants. Almost every one remembers the wry faces
which the first glass of port produced. Unsophisticated instinct is
invariably unerring; but to decide on the fitness of animal food from
the perverted appetites which its constrained adoption produces; is to
make the criminal a judge in his own cause: it is even worse, it is
appealing to the infatuated drunkard in a question of the salubrity of
brandy.

What is the cause of morbid action in the animal system? Not the air we
breathe, for our fellow-denizens of nature breathe the same uninjured;
not the water we drink (if remote from the pollutions of man and his
inventions (The necessity of resorting to some means of purifying water,
and the disease which arises from its adulteration in civilized
countries, is sufficiently apparent. See Dr. Lambe's "Reports on
Cancer". I do not assert that the use of water is in itself unnatural,
but that the unperverted palate would swallow no liquid capable of
occasioning disease. )), for the animals drink it too; not the earth we
tread upon; not the unobscured sight of glorious nature, in the wood,
the field, or the expanse of sky and ocean; nothing that we are or do in
common with the undiseased inhabitants of the forest. Something, then,
wherein we differ from them: our habit of altering our food by fire, so
that our appetite is no longer a just criterion for the fitness of its
gratification. Except in children, there remain no traces of that
instinct which determines, in all other animals, what aliment is natural
or otherwise; and so perfectly obliterated are they in the reasoning
adults of our species, that it has become necessary to urge
considerations drawn from comparative anatomy to prove that we are
naturally frugivorous.

Crime is madness. Madness is disease. Whenever the cause of disease
shall be discovered, the root, from which all vice and misery have so
long overshadowed the globe, will lie bare to the axe.
