ual number of insane persons is therefore much larger than
appears by the documents submitted to the committee." The Medical
Society of Connecticut appointed a committee of their number, composed
of some of the most eminent physicians in the state, to ascertain and
report the whole number of insane persons in that state. The committee
say, in their report, "The number of towns from which returns have
been received is seventy, and the cases of insanity which have been
noticed in them are five hundred and ten." The committee add, "fifty
more towns remain to be heard from, and if insanity should be found
equally prevalent in them, the entire number will scarcely fall short
of _one thousand_ in the state." This investigation was made in 1821,
when the population of the state was less than two hundred and eighty
thousand. If the estimate of the Medical Society be correct, the
proportion of the insane to the whole population would be about one in
two hundred and eighty. This strikes us as a large estimate, and yet a
committee of the legislature of that state in 1837, reported seven
hundred and seven insane persons in the state, who were either wholly
or in part supported as _town paupers, or by charity_. It can hardly
be 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
