garding those people, to any promulgated
from Exeter Hall. Experience also proves the former to be the best. You
hear of the poor negroes, or colored people, as you call them, being
beaten with many stripes by their masters and overseers. But owing to
the fact that they consume less oxygen than white people, and the other
physical differences founded on difference of structure, they beat one
another, when free from the white man's authority, with ten stripes
where they would get one from him. They are as much in slavery in Boston
as in New Orleans. They suffer more from corporeal or other punishments
in the cellars and dark lanes and alleys of Boston, New York and
Philadelphia, by the cruel tyranny practiced by the strong over the weak
and helpless, than an equal number in Southern slavery. In slavery the
stripes fall upon the evil disposed, vicious, buck negro fellows. But
when removed from the white man's authority, the latter make them fall
on helpless women and children, the weak and the infirm. Good conduct,
so far from being a protection, invites aggression.

But what connection have these observations, you may say, with the
subject of Dr. Hall's inquiries, and what light do they throw on
tubercular disease? They show that there exists an intimate connection
between the amount of oxygen consumed in the lungs and the phenomena of
body and mind. They point to a people whose respiratory apparatus is so
defective, that they have not sufficient industry and mental energy to
provide for themselves, or resolution sufficiently strong to prevent
them, when in freedom, from being subjected to the arbitrary, capricious
will of the drunken and vicious of their own color, who may happen to
have greater physical strength and more cunning; they show that Phthisis
is a disease of the master race, and not of the slave race--that it is
the bane of that master race of men, known by an active haematosis; by
the brain receiving a larger quantity of aerated blood than it is
entitled to; by the strong development of the circulating system; by the
energy of intellect; by the strength and activity of the muscular
system; the vivid imagination; the irritable, mobile, ardent and
inflammatory temperament, and the indomitable will and love of freedom.
Whereas the negro constitution, being the opposite of all this, is not
subject to Phthisis, although it partakes of what is called the
scrofulous diathesis. In the negro constitution, as the Fren
