Thomas Jefferson Papers

To Thomas Jefferson from James Madison, 3 July 1804

Williamsburg July 3d. 1804

Dear Sir

I have often regreted, that I parted with the Instrument, which you mention; & which would have been so convenient in the very useful work you have in View. Cap. Hutchins prevailed upon me to let him have it in the year 84. I intended to have procured one more perfect in its Construction; & this Summer have given Directions for that Purpose. I have been anxious to obtain one as a travelling Companion this Fall, in order to ascertain the Latitude of some particular Places in Virginia; & supposed such an Instrument might be procured in N. York, or Philadelphia. In Case of a Disappointment, I had some Thoughts of seperating the common Hadley’s Quadrant into convenient Pieces, which might be united by Slides, or other means, when it was required for Use,—I am satisfied an ingenious mechanic would render one very portable in this way, whilst the accuracy of the Instrument would be but little impaired.

Had the Instrument remained in my Possession, I should certainly have taken great Pleasure in forwarding it, without Delay.

I am Dr Sir with sincere Respect & Esteem Yr. Friend & Servt

J Madison
