Thomas Jefferson Papers

To Thomas Jefferson from Charles Willson Peale, 14 December 1806

Museum Decr. 14th. 1806

Dear Sir

Wishing to find some means of improving the Machinery of your Polygraph, I have since writing the foregoing, examined critically every part, and now pronounce it as perfect as can be made in the present construction of moovement—but must acknowledge that the touch of the Pens at the top is not what it ought to be. This I have found to be the case in some Machines on an larger scale, and where I could do it, have made the fastening of the Paper lower down. However I hope you will find this Machinery better than the other, otherwise my labour is in vain.

Such as the enclosed are framed and hung with my Paintings in the Museum. I mean in role with the shade of Judge Wythe which I shall put into the Post Office this evening. The Box containing the Polygraph is sent to the Mail Stage office. I am with high regard yours affectionately

CW Peale
