[5] Mr. Needles says: "He was visited by William Hartshorn and Samuel
Coates of this city (Philadelphia), and gave correct answers to all
their questions--such as how many seconds there are in a year and a
half. In two minutes he answered 47,304,000. How many seconds in
seventy years, seventeen days, twelve hours. In one minute and a half,
2,110,500,800. He multiplied nine figures by nine," etc., etc.

[6] Accounts of these two black men were prepared by Dr. Rush, for the
information of the London Society.

[8] In a letter to M. de Meusnier, dated January 24, 1786, Mr.
Jefferson says: "I conjecture there are six hundred and fifty thousand
negroes in the five southermost states, and not fifty thousand in the
rest. In most of the latter, effectual measures have been taken for
their future emancipation. In the former nothing is done toward that.
The disposition to emancipate them is strongest in Virginia. Those who
desire it, form, as yet, the minority of the whole state, but it bears
a respectable proportion to the whole, in numbers and weight of
character; and it is constantly recruiting by the addition of nearly
the whole of the young men as fast as they come into public life. I
flatter myself that it will take place there at some period of time
not very distant. In Maryland and North Carolina, a very few are
disposed to emancipate. In South Carolina and Georgia, not the
smallest symptom of it; but, on the contrary, these two states and
North Carolina continue importations of slaves. These have long been
prohibited in all the other states." Works, ix, p. 290.
