less than the white man voluntarily imposes on himself. If force be used
to make them do more, they invariably do less and less, until they fall
into a state of impassivity, in which they are more plague than
profit--worthless as laborers, insensible and indifferent to punishment,
or even to life; or, in other words, they fall into the disease which I
have named Dysesthaesia Ethiopica, characterized by hebetude of mind and
insensibility of body, caused by over working and bad treatment. Some
knowledge of the ethnology of the prognathous race is absolutely
necessary for the prevention and cure of this malady in all its various
forms and stages. Dirt eating, or Cachexia Africana, is another disease,
like Dysesthaesia Ethiopica, growing out of ethnical elements peculiar to
the prognathous race. The ethnical elements assimilating the negro to
the mule, although giving rise to the last named disease, are of vast
importance to the prognathous race, because they guarantee to that race
an ample protection against the abuses of arbitrary power. A white man,
like a blooded horse, can be worked to death. Not so the negro, whose
ethnical elements, like the mule, restricts the limits of arbitrary
power over him.

Among the four millions of the prognathous race in the United States, it
will be difficult, if not impossible, to find a single individual negro,
whom the white man, armed with arbitrary power, has ever been able to
make hurt himself at work. It is beyond the power of the white man to
drive the negro into this long continued and excessive muscular
exertions such as the white laborers of Europe often impose upon
themselves to satisfy a greedy boss, under fear of losing their places,
and thereby starving themselves and families. Throughout England,
nothing is more common than decrepitude, premature old age, and a
frightful list of diseases, caused by long continued and excessive
muscular exertion. Whereas, all America can scarcely furnish an example
of the kind among the prognathous race. The white men of America have
performed many prodigies, but they have never yet been able to make a
negro overwork himself.

There are other elements peculiar to the Nigritian, on which the
disease, called negro consumption, or Cachexia Africana, depends. But
these belong to that class which subject the negro to the white man's
spiritual empire over him. When that spiritual empire is not maintained
in all its entirety, or in other words, wh
