4036. INVENTIONS, Polygraph.—
A
Mr. Hawkins, of Frankford, near Philadelphia,
has invented a machine which he calls a polygraph,
and which carries two, three, or four
pens. That of two pens, is best; and is so perfect
that I have laid aside the copying press,
for a twelve-month past, and write always with
the polygraph. I have directed one to be made,
of which I ask your acceptance.—
To C. F. Volney. Washington ed. iv, 572.
