supposed that more than _two-thirds_ of the insane in Connecticut
belong to families _unable to support them_. On this supposition, the
whole number would be greater than the estimate of the Medical Society
sixteen years previous, when the population was perhaps thirty
thousand less. But to avoid the possibility of an over estimate, let
us suppose the present number of insane persons in Connecticut to be
only seven hundred.

The population of the state is now probably about three hundred and
twenty thousand; according to this estimate, the proportion of the
insane to the whole population, would be one to about four hundred and
sixty. Making this the basis of our calculation, and estimating the
slaves in the United States at two millions, seven hundred thousand,
their present probable number, and we come to this result, that there
are about six thousand insane persons among the slaves of the United
States. We have no adequate data by which to judge whether the
proportion of lunatics among slaves is greater or less than among the
whites; some considerations favor the supposition that it is less. But
the dreadful physical violence to which the slaves are subjected, and
the constant sunderings of their tenderest ties, might lead us to
suppose that it would be more. The only data in our possession is the
official census of Chatham county, Georgia, for 1838, containing the
number of lunatics among the whites and the slaves.--(See the Savannah
Georgian, July 24, 1838.) According to this census, the number of
lunatics among eight thousand three hundred and seventy three whites
in the country, is only _two,_ whereas, the number among ten thousand
eight hundred and ninety-one slaves, is _fourteen_.

2d. _The Deaf and Dumb._--The proportion of deaf and dumb persons to
the other classes of the community, is about one in two thousand. This
is the testimony of the directors of the 'American Asylum for the Deaf
and Dumb,' located at Hartford, Connecticut. Making this the basis of
our estimate, there would be one thousand six hundred deaf and dumb
persons among the slaves of the United States.

3d. _The Blind._--We have before us the last United States census,
from which it appears, that in 1830, the number of blind persons in
New Hampshire was one hundred and seventeen, out of a population of
two hundred and sixty-nine thousand five hundred and thirty-three.
Adopting this as our basis, the number of blind slaves in the United
State
